Great Gourds! Pumpkins & More

As you select and prepare to carve a pumpkin this Halloween, you should pause to reflect on the vast impact this humble gourd has had on our cultural history.

Pumpkins generally trace their origins to Central America, and collections of seed have been found in Mexico dating back several thousand years. Today, pumpkins are grown on every continent except Antarctica, and have found their way into our legends and traditions, kitchens, kitschy competitions, and media.

In literature, we should remember poor Ichabod Crane, knocked for a loss by a pumpkin lobbed by the headless horseman of Washington Irving’s “Legend of Sleepy Hollow,” or even Cinderella’s enchanted carriage. Then, of course, there is the now classic book and television special “It’s the Great Pumpkin, Charlie Brown,” or the more edgy Pumpkin King, in Tim Burton’s “Nightmare Before Christmas,” to say nothing of the early 90’s band, Smashing Pumpkins.

Culinary uses range from traditional pumpkin pie filling and pumpkin butter, to protein-rich seeds, which can be roasted and salted. The meat of the pumpkin can also be boiled or fried, diced or pureed, and has found its way as a filling for sweet Italian ravioli, soups, and numerous vegetarian dishes. Some microbreweries even produce a seasonal pumpkin ale.

Lately, florists have gotten into the act and use pumpkins as containers to fill with autumn-themed flowers as centerpieces or gift baskets.

If these notions have you seeing orange, then keep in mind that pumpkins come in a host of colors, from the red “Rouge D’Etant” to varieties in gold, buff, greenish-blue, and blue. New cultivars named “Casper” or “Baby-Boo” offer white pumpkins, which might be particularly ghoulish when carved.

Another important variety includes the giant pumpkins, perfect for competitions. Gourd gardeners are now approaching the 1,500 pound barrier on individual specimens. The 1,000 pound mark was broken in 1996 with the variety “Atlantic Giant,” and within the past several years a 1,458 pound specimen made its way into the Guinness Book of Records. There are also articles about a man who grew more than 2,700 pounds of pumpkin on a single vine.

Another somewhat less-dignified competition includes the popular “pumpkin flings” held each year, such as the “World Championship Punkin Chunkin” in Delaware. Approximately 30,000 people gather to watch medieval style catapults, 100 foot-long cannons, and four-story tall slingshots shoot ten-pound pumpkins up to 4,000 feet through the air.

However, pumpkins no doubt have their greatest appeal when artfully carved and illuminated as Jack-o’-Lanterns for Halloween. And while this tradition is relatively new, especially in the New World, its origins extend back thousands of years into the misty past.

We begin with Celts celebrating the “Feast of Samhain” on November 1. The feast takes its name from the Gaelic Samhraidhreadh, meaning summer’s end, and is a celebration of the final harvest, which featured bonfires, food, dancing, and costumes. It is also an important mystical time, the start of a new year, when the transition between seasons opens a doorway into the realm of spirits.

Samhain is also identified as a godlike individual, sometimes defined as a “lord of the dead.” This mythic figure is depicted carrying a lantern or spectral fire, with which he guides lost and roaming spirits to the supernatural realm. His appearance is also associated with Will-o’-the-Wisp, or Welsh “Corpse Candles,” ghostly flames which move over bogs and through cemeteries.

The Feast of Samhain began its “conversion” to Halloween in 844, when Pope Gregory transferred the Christian feast for “All Saints” or “All Hallows” (meaning “holy”) from May 13 to November 1, to coincide with the Celtic “pagan” festival.

As centuries passed and traditions fused, the figure of Samhain guiding spirits with a spectral light was seemingly recast by Irish storytellers as a Christianized Jack-o’-Lantern. Incidentally, “jack” is no more than a term for any common man, and therefore Jack-o’-Lantern simply means “man with a lantern.”

The tragic legend of Jack holds that he was an inveterate prankster whose cunning ran afoul of the devil himself. Upon his death Jack finds that he is barred from heaven for never having performed an unselfish act, and similarly banned from hell. Doomed to a twilight existence between worlds, Jack carves a turnip and creates a lantern to guide his way, lighting it with an infernal ember coaxed from the devil.

The tradition of carving lanterns out of turnips and lighting them with embers or oil continued for centuries among Irish households. Moreover, like the medieval practice of carving gargoyles on cathedrals to scare off malevolent forces, the Irish carved ghastly visages into their turnips to ward off those evil spirits who roamed the countryside.

In time, of course, Irish immigrants brought their turnip carving to the new world, where they happily discovered a much larger gourd suitable for carving. And yet, one has to wonder what the ancient Celts and their Druid priests might have made of “punkin chunkin.” We will have to ask them when they show up again on the next Samhain.

Fall -- for the New Garden Year

The days are growing shorter and colder, and your mailbox is already full of winter catalogs. You might think your garden chores are finished for the season. Think again. The garden year actually begins with the misty, mellow days of autumn.

Spring only seems like the perfect time to resume work on your landscape. After all, garden centers are overflowing seductively with flowering plants, community groups plan Arbor Day celebrations and all around, you can hear lawnmowers chomping on fast-growing grass.

However, planting trees and shrubs in the spring gives the plants very little time to overcome transplant shock and develop essential root systems before summer's scorching heat and dry conditions.

Fall is the ideal and appropriate time to plant and transplant trees, shrubs and many perennials. In fact, it is important to get both broad-leaved and needle-leaved evergreens in the ground no later than mid-autumn. Species like holly, spruce, juniper, pine, fir and hemlock do not enter a dormant phase. Instead, they continue to transpire actively through their leaves during winter, which requires fully functioning root systems capable of taking water from the soil.

Planting as soon as possible allows roots to reestablish vital root hairs or fibers, which will begin supplying water. This is especially important for any plant with a root system that may have been damaged while being dug up for transplanting. Moreover, fall planting gives transplants two full growing seasons to become settled in before the dog days of summer. Water thoroughly after planting – and keep watering every week, if dry conditions ensue.

Planting and transplanting deciduous trees and shrubs — like maples, dogwoods, lilacs, hydrangea and viburnum — is best done after their leaves have fallen, signaling dormancy. Without the burden of supplying water and nutrients to leaves and branches, the tree can focus on growing new roots and preparing for blooming and leafing out in spring.

Fall is also the season for planting almost all hardy spring-flowering bulbs, such as tulips, scilla, crocuses, hyacinths and narcissus, which includes daffodils and jonquils. Some gardeners prefer digging individual holes for each bulb, especially with more formal species like tulips. Prepare a hole two-and-one-half times deeper than the bulb’s diameter. Before setting the bulb in place, toss in a handful of bonemeal or a dose of a “complete fertilizer,” then fill in the hole.

A better approach for other bulbs might be to treat them like perennials. Prepare a well-drained planting area or bed by removing any weeds and debris and topping the area with four to six inches of compost. Incorporate the compost into the existing soil with a shovel, spade or rototiller, working the amendment down into the top 10 or 12 inches of existing earth. Then insert the bulbs into the fluffy, organically-rich planting medium, preferably in groups or clumps — far more attractive than formal rows Many gardeners use this type of preparation to “naturalize” bulbs like crocus and daffodils, thereby creating a flow of bright, nodding blooms between trees on a lawn, or down a hillside. Such plantings, also called “drifts,” are often seen along parkways and in natural garden areas.

Rescue, renovate or rethink your lawn during the fall as well. If you have not worked on it in autumn, anything you do in spring will be too little and too late. Start by investing in a simple $5-10 soil test through your local cooperative extension service office. The test will provide complete and sound directions for applying lime and fertilizer. Remember that autumn is the best and sometimes the only time to feed most turfgrasses.

Like trees and shrubs, grass plants continue to develop roots throughout winter. Feeding the roots and aiding their development now will ensure a healthier, more drought-tolerant lawn come spring and summer.

Lawns could also do with a breath of fresh air about now. Consider contracting with a landscaper to core aerate the lawn, or rent an aerator and do it yourself. The process, which normally costs less than $100 regardless of who does the work, will remove plugs from the soil and allow air to infiltrate deeper into the ground and stimulate grass roots. The small holes will improve drainage and help nutrients and organic matter — such as grass clippings and leaves — work their way into the soil horizon.

You also can add valuable organic matter to your lawn by mulching or grinding up leaves with a mower. Otherwise, rake up fallen leaves and other debris and add them to the compost pile to prevent the spread of fungal diseases during the wet winter months.

If your lawn has been a disappointment, cut it down to size. Autumn is the perfect time to create new planting beds. Either remove sod with a shovel or leave it in place and smother it with cardboard and newspaper. Apply six, eight or more inches of mulch over the top of the bed and walk away. Worms and microorganisms will gobble up grass, roots and mulch while you sip hot cocoa indoors, leaving you with a brand-new planting area to play with in spring. Instead of complaining about your lawn, spend winter thumbing through colorful garden and seed catalogs.

Turning Over a New Leaf!

Glorious Autumn! Keat's season of mists and mellow fruitfulness. It is also (alas) the season of the rake. It seems that you spend the better part of your precious weekends just raking up leaves. And just when you have gotten them under control, along comes a brisk gust of wind, a sprinkling of rain, and your lawn is covered all over again. Groan! Time to drag out the rake once more.

Here is a solution to simplify your fall and improve the long-term health and vigor of your lawn, trees, and garden beds:

Mulch ado about leaves.
There are a large number of expensive, awkward, and sometimes useful products being hawked to suck up your leaves and turn them into mulch. There are blower-vacs which blow leaves into a pile which you can then suck up and shred. There are chipper-shredders with elephant trunks that also allow you to suck up and shred leaves, although you have to rake them into piles first. And lawn jockeys with disposable incomes can check out the over $1,200 self-propelled machines which act like gas-powered vacuum cleaners on your lawn (watch out for small pets).

Mower for less.
These contraptions may not be the solution for you. However, if you are like most homeowners, you may not have realized that your lawn mower is already a deluxe leaf mulcher in its own right. And perhaps the easiest way to deal with leaves is to mow them right back into the lawn itself. Forget back-breaking raking and bagging!

Please note that mower-mulching works best when leaves are relatively dry and are no more than one inch deep. Deeper "drifts" might need to be partially raked first -- or plan to run back and forth over the leaves several times. And do not worry if your model is not a dedicated mulching mower, any type of mower will do.

Start your do-it-yourself "mulchinator" by setting the mower to a normal three-inch height. Remove bagging attachments and block off the discharge chute on a rear-discharge machine. Then run your mower over the lawn while walking slowly, giving the mower blades plenty of time to shred up the leaves.

If your mower has a side discharge chute, you will probably want to start on the outside perimeter of your lawn and start mowing inward. This will keep the leaf-bits on the lawn, and even allow you to mow over them a few more times. Of course, some folks like to "blow" shredded leaves into ground cover areas, under foundation plantings, or into wooded areas, adding to the organic content of soils there, which is another option.

If your first pass over the lawn has left a significant quantity of whole leaves, go back over the leaves while mowing at a right angle to the first cut, perhaps walking even more slowly. Leaves take more work than grass, especially if they are somewhat damp.

Stay out of the gutter!
It is important not to blow whole or shredded leaves into streets, storm drains, or nearby streams. Those innocent-looking particles can create problems for sensitive aquatic life by suffocating plants, fish eggs, and insect larvae, clouding the water, tying up oxygen, and altering the stream's pH (increasing toxic acidity). And that is also why you should never rake leaves into the street or gutter: leaf leachate always ends up in your neighborhood stream.

Too many leaves?
The swirling mass of leaves may seem daunting at first, but the final particle size will be one-tenth of the original leaf. This will make it easily digestible by worms and bacteria. Skeptics often voice a concern that shredding leaves into turf areas will overwhelm and kill their lawn. Not at all! In fact, research at the Rodale Institute in Pennsylvania found that earthworms will actually drag a one-inch deep layer of organic matter into their burrows in just a few months, loosening and enriching your soil, and feeding the roots of your lawn for free.

Numerically, while you may imagine that all of those leaves will add up to far too much organic matter for your lawn, the fact is that 30 tall paper bags full of leaves, once shredded, will break down within a season to about one cubic yard of leaf mold or compost. Applied to your lawn as a topdressing, you would only be able to cover about 48 square feet (a six foot by eight foot patch). In fact, to topdress a lawn properly, most savvy gardeners have to import tons of commercial compost above and beyond the compost they make at home! Fear not: you will never have too many leaves or too much organic matter!

Your lawn needs leaves.
For decades, homeowners have bagged their grass clippings and leaves and sent them off to a landfill. And lawn chemical salespeople successfully and profitably sold the idea that healthy lawns needed bimonthly fertilizer and pesticide applications. Times have fortunately changed. The fact is that lawns and gardens can be maintained organically, for the most part, and without toxic inputs, just by recycling the natural materials already in place. When you bag up your clippings and leaves, you are short-circuiting the natural recycling process.

Think of the cycle this way: tree roots absorb water, minerals, and a host of nutrients from the soil. These materials are used to add girth to the tree trunk and boughs, set forth new branches, grow more roots, and grow leaves, flowers, and fruits or seeds. In a natural setting, such as a forest or woodlot, leaves, small twigs, blossoms, and fruits drop to the ground and slowly decompose, returning all of the original organic building blocks to the soil for future use.

What happens when you bag up leaves? How is that organic matter going to get back to the soil for the tree to use in coming years? You may think that by fertilizing your lawn you are returning everything the tree needs. Wrong! Of the more than one dozen major and minor nutrients that plants need to grow, how many are in your bag of fertilizer? And what about the organic matter that creates humus, the very soul of soil itself?

Bagging leaves and grass is equivalent to strip mining. The minerals, nutrients, and organic matter are continually stripped away year after year. Eventually, without those vital materials, your trees, your garden, and your lawn will start to suffer. It is time to undo this damage by getting that organic matter back into the soil. And you can easily start just by mowing your leaves into your lawn.

It's in the bagger!
There are other options and uses for some of your shredded leaves. For example, if your mower does have a bagging attachment, you might want to take the shredded material and start using it to mulch some of your trees and shrubs. This is also true for gardeners with some of the fancier shredding equipment. Apply up to four inches deep, and your mulch layer will also act as a blanket to prevent frost upheaval in planting beds, which is especially damaging to bulbs, tuberous flowers, and some half-hardy perennials. You will also be feeding and protecting your plants and preventing weed growth for almost a full year.

A compost pile or bin is another excellent half-way point for shredded leaves. Those smaller leaf particles break down in less than half the time of whole leaves, and you can fit a prodigious quantity of shredded leaves into your bin. Also, if you find that you are cutting some grass while shredding leaves, you are probably creating the perfect blend of carbon and nitrogen-rich materials to ensure a hot, fast-working compost pile.

Recommended chores.
Mulching leaves into lawns is just the first step toward a naturally healthy lawn and environment. You should also consider aerating your lawn by either renting a core-aerating machine (about $70) or hiring a lawn care firm ($75 and up depending on overall lawn size). Aerating breathes life into compacted soils and helps organic matter filter deeper into subsoils and root zones. You should also test your soil with a kit from your county or municipality's local Cooperative Extension Service (costs are about ten dollars) to determine proper nutrient application rates. Your soil test will also indicate the type and quantity of lime your lawn needs; local soils are naturally acidic. And don't forget: fall is the only beneficial time to consider feeding your lawn -- only use a slow-release or organic nutrient source to feed the soil and your lawn's roots all winter long.

Autumn Leaves Feed Healthy Lawns

Autumn is perhaps the most mellow and reflective season of the year. Shorter days encourage reading in the evening while crisp air and colorful vistas invite weekend hikes and trips to the countryside. Regrettably, too many people waste their precious weekends raking leaves into piles or shatter the quiet peace of sunny afternoons with leaf blowers. There is a better solution.

Rather than trying to rid your lawn of fallen leaves, you should actually consider leaving them where they are. It is nature’s way to recycle, after all. Certainly no one is raking up and bagging the leaves which fall in wooded parks and forests. Given a bit of time, all of the leaves are transformed by worms, bacteria and other organisms into rich humus, which will continue to feed trees, shrubs, and other plants year after year for millennia.

Your yard is simply an extension of the same natural process. Trees around your property draw nutrients and minerals from the soil, converting those elements into new leaves and branches. By raking up those leaves, you essentially short-circuit the natural cycle by which nutrients are returned to the soil. After a number of years, the soil will lose its fertility. In fact, carting off leaves and grass clippings is akin to strip mining, ultimately affecting the health of everything you are trying to grow.

Spreading costly fertilizers on your lawn may restore some nutrients, but not all of the vital minerals and organic matter needed for healthy, vigorous plants. Leaves, on the other hand, contain all of the nutrients and micronutrients your lawn needs. The trick is getting those leaves back into the soil without smothering your lawn in the process.

Enter the lawnmower. For the past ten years, almost all new lawnmowers sold have been mulching mowers. After decades of bagging clippings, a majority of homeowners have learned that it is best to “grasscycle” their lawn clippings when they mow. Clippings left in place quickly decompose and provide nutrients to keep the lawn healthy.

Your lawnmower can now do double-duty as a leaf-mulcher. Mower blades can easily shred whole leaves into small pieces, approximately one-tenth their original size. Your once-daunting bounty of leaves will disappear into a thin layer of tiny particles easily digested by worms and bacteria. In fact, a healthy earthworm population is capable of dragging a one-inch layer of organic matter down into their underground burrows in just a few months. Unseen by human eyes, they are diligently loosening and enriching your soil, and feeding the roots of your lawn for free. Perhaps you should think of your mower as a food processor for worms!

Begin your regimen of leaf-mulching by setting the mower to a normal three-inch height. Remove bagging attachments and block off the chute on a rear-discharge machine. Run your mower over the lawn while walking slowly, giving the mower blades plenty of time to shred up the leaves. Please note that mower-mulching works best when leaves are relatively dry and are no more than one inch deep. Do not wait until every last leaf has fallen before getting started.

If your mower has a side discharge chute, you will probably want to begin on the outside perimeter of your lawn, blowing your chopped leaves onto unmowed areas, and continue mowing inward. This will keep the leaf particles on the lawn, and even allow you to mow over them a few more times. Some savvy gardeners like to direct the discharge of shredded leaves into ground cover areas or under foundation plantings where organic matter is also welcome.

If your first pass over the lawn has left a significant quantity of whole leaves, go back over the leaves while mowing at a right angle to the first cut, perhaps walking even more slowly. Leaves take more work than grass, especially if they are somewhat damp.

There are other options and uses for some of your shredded leaves. For example, if your mower does have a bagging attachment, you might want to apply the shredded material as a mulch two to four inches thick under your trees and shrubs. Do not pile the mulch directly against tree trunks.

Shredded leaves can also be applied to other planting beds, such as perennial borders and herb gardens. Avoid applying mulch until after the first hard freeze. A two to three inch mulch layer will help maintain a uniform soil temperature all winter and protect tender root systems. The mulch blanket will also prevent frost upheaval caused by frequent thawing and refreezing, which is especially damaging to bulbs, tuberous flowers, and some half-hardy perennials.

Naturally, the leaf mulch will also feed your plants by recycling nutrients, conserve soil moisture during dry spells, and prevent the emergence of weeds.

You can also add your shredded leaves to a compost pile or bin. The smaller leaf particles decompose in about 75 percent of the time required by whole leaves, and you can further add a astonishing volume of shredded leaves into the bin, which is useful for properties with numerous mature trees. In addition, if you find that you are cutting some grass while running over the leaves, you are probably creating the perfect blend of materials to ensure an effective, fast-working compost pile. Your shredding efforts may even reward you with nutrient-rich compost ready for use in the Spring.

Composting With Pallets

Wooden shipping pallets are easily recycled into large, heavy-duty compost bins. Pallets are available for free from many area businesses, assemble in minutes, and with them you can produce rich humus, mulch and compost year after year. Here's how:

A Simple Pallet Bin

Obtain five pallets with narrow spaces between slats (1/2" - 1") and of uniform size. Many pallets measure 40" by 48" and will form a 48 cubic foot capacity bin. Pick up pallets from loading docks, freight companies, hardware stores, product wholesalers, nurseries and garden centers. Each year, American businesses send more than 300 million pallets to landfills and incinerators -- there are always plenty around for free.  Good places to check are print shops, tire wholesalers, even central post office facilities which handle bulk mail.

To begin, place one pallet (slat-side up) on level ground. This pallet is the bottom of your bin and will allow for good drainage and aeration by keeping yard trimmings above the ground. Properly drained and aerated compost decomposes quickly and without odors.  Some people like to staple or nail hardware cloth to the slats to provide a smooth surface for shoveling and to prevent materials falling between the slats, although if the space between the slats is less than one inch, this step is generally unnecessary.

Arrange the remaining pallets upright around each side of the base to form a box, short (40") sides up. Use spare wire, coathangers, or nylon rope to fasten the pallets together. Join pallets at each corner, lashing both the top and bottom. You can gain access to your compost pile by unfastening one side of a pallet and swinging it out like a hinged door.

Multi-Bin Units

Large properties and institutions like schools and churches may require a larger compost bin system to accommodate their materials. And gardeners looking for quick compost may prefer a multi-bin system to make turning materials easier.

First, construct a single bin as described above. Then expand your compost system by setting another pallet to the right of the base of your existing bin, and adjoining it. Form another box with three additional pallets to form the door and sides of the new bin. The two bins will share one side. Additional "bins" can be added-on using just four pallets at a time.

Two-bin systems allow easy turning of materials by transferring decomposing trimmings from one side to the other. Three-bin systems are favored by aggressive composters, with one bin used for newer materials, which are "turned" or transferred into the second bin after several weeks (or months), and later into the final "curing" bin for several weeks or months, prior to use. Churches and schools frequently construct three, four, or more bin systems to handle materials.


Lifespan and Maintenance

Pallet bin sides generally last from four to six years, depending on the level of active use. Bases last one to two years and need to be replaced. Just drop another fresh pallet over the old base after removing any compost still in the bin -- keep the new base as level as possible. The decomposing pallet will eventually turn to compost. Check corner lashing periodically and replace every several years, or as needed.

Piles and Pallets and Bins

Some composters prefer to use a free standing pile or "heap." Even this simple method of composting can be enhanced by using pallets to improve drainage and aeration. Use a pallet as the base of your compost "heap," rather than the layer of twigs or brush that are traditionally recommended. This smooth, even base will permit materials to be turned much more easily.

To create a pallet base, use a pallet with narrow 1/2" spaces between slats. If a pallet with narrow spaces is not available, try stapling or tacking a layer of hardware cloth to the top of the pallet to keep material from falling through the spaces. Two adjacent pallets on the ground create a handy work area for easy turning.

Homeowners who already have one of many commercially available compost bins can also improve good drainage and aeration. Simply set your open-base bin atop a wooden pallet. A layer of brush is now no longer required, thereby expanding you prefabricated unit's capacity.

Autumn Lawn Care

Homeowners often make the mistake of thinking that the secret to a good lawn is lots of work in the spring. However, perhaps the most vital period of time for healthy turf is the fall, where proper feeding and care will result in a naturally lush and beautiful lawn in the spring, which will keep its green all year long.

Grasscycling for All Season Lawn Care

Healthy lawn care year-round starts and ends with grasscycling -- leaving those nutrient-rich clippings on the lawn when you mow. Do not be fooled by the old myth of bagging clippings when the weather turns nippy. Clippings can be left behind right up to the last mowing of the year. Worms will continue to pop out of their burrows and drag clippings deeper into the soil as long as soil is not frozen, and bacteria will continue to help break down the organic clippings even under a mantle of snow!

Grasscycling Means Leaf-cycling

As leaves fall onto lawn areas, your lawnmower can be used as a mobile chipper-shredder to run over the leaves and shred them into smaller particles. No raking or bagging required! You can continue to mulch leaves right into your soil all autumn long provided that the layer of fallen leaves does not exceed more than half and inch. It also helps if the leaves are primarily dry. Those colorful leaf “bits” provide much-needed organic matter for your soil. Soils that are organically well-fed are healthy soils which will easily grow healthy lawns.

Fall is Feeding Time

One of the major causes for turf disease and unhealthy lawns is overfeeding and fertilizing at the wrong time of year. Bad feeding practices and relying on synthetic “quick fix” fertilizers and lawn chemicals can have long term harmful impacts on your lawn and on the environment, especially groundwater and streams. To ensure a healthy lawn and environment, feed your lawn now and do it right.
  • Use your soil test results to determine proper application rates. If you haven’t tested your soil -- do it now! Call your local Cooperative Extension Service office for a reliable five-ten dollar test kit.
  • Underfeed rather than overfeed; too much fertilizer leads to disease and thatch. Also, grasscyclers are already recycling a substantial amount of nutrients every time they mow.
  • Lawns should “eat” slowly. Avoid quick-release or water-soluble fertilizers. Generally, using a organic mix or low-analysis natural fertilizer (contents usually include bloodmeal, bonemeal, rock phosphate, and various manures), will provide plant roots will most of the nutrients they’ll require all year long. If synthetics are more readily available, make sure that the fertilizer is water-insoluble, or you’ll lose most of the nutrient benefit after the first rain.
  • Compost is a near complete meal -- and hefty dose of valuable organic matter -- for most lawns. You can use your own home-grown compost or purchase a commercial product, the most common being Milorganite, although many communities (and zoos!) often sell composted leaves and biosolids locally, in addition to various composted manure products. Compost can be spread over a lawn area as a topdressing about one-quarter inch thick.
  • Apply lime and other rock minerals, as indicated by your soil test. Normally, ground calcitic limestone is preferred over dolomitic lime, unless your soil suffers from a magnesium deficiency. Using ground rather than powdered lime will also ensure that the lime breaks down slowly during the winter and spring without washing off.

A Breath of Fresh Air

Aerating lawns is perhaps one of the most beneficial measures to ensure healthy soil and vigorous roots. Core aeration, which pulls plugs out of the soil, is the most effective method, and can be done by a lawncare contractor -- or by renting the equipment. The cost is usually the same either way. Aeration helps air reach organisms in the soil which break down organic matter and produce nutrients for the grass roots. It also allows organic matter, like leaf and grass particles or compost, to enter deeper into the plants’ root zones, improving soil and lawns all at once. The soil “plugs” also provide minerals for the soil surface.

Going to Seed

This is your last chance to get cool weather grass growing in bare patches. For trouble areas, it is best to roughen up the area with a rake, topdress with a thin layer of compost, and then apply the appropriate variety of grass seed and water evenly.

Remember that fall is the real beginning of the lawn care season. A little extra work now will allow you to enjoy those longer, warmer days of spring and summer a lot more next year.
