After the leaves fall, it's time to rake them up or collect them with a lawnmower attachment then dispose of them, right? No! Instead of removing them entirely from your lawn, use these tips on how they can actually benefit your lawn and your flower beds too. The money homeowners will spend next Spring on lawn and garden fertilizers, mulch and bagged compost... they might have saved if they’d simply used those leaves now.
Why Are Leaves Valuable to the Gardener?
It’s simple. When incorporated into soil, fall leaves:
Add nutrients, including phosphorous and potassium
Increase the soil’s microbial life
Boost its water-holding capacity
Improve its structure, known as tilth
Not to mention that leaves are free! It takes little effort on your part to get them working for you. Here are five ways to use them:
1. Mow Them Into the Lawn
Together, shredded leaves and grass clippings add carbon (leaves) and nitrogen (grass) to the soil, reducing your need to add store-bought fertilizers later.
Here’s how: Use a mulching mower. If there’s a bag, take it off and mow with the discharge chute facing toward the lawn, so the clippings blow on the grass instead of on the street or driveway. Set the mower height at about 3 inches. Make another pass if the leaves are still in big pieces. The shredded leaves should sit no more than ¾ inch deep on the grass. Over the winter they will break down into the soil and be gone by spring.
2. Add Them to Vegetable Beds
You can incorporate whole or chopped leaves into any cleared-out vegetable beds. They will mostly decompose over the winter, then in spring you can mix in whatever is left. If you don’t want to see leftover leaves in your beds, shred them first.
Don’t have a shredder? A garbage can and a string trimmer will work. Use a 55-gallon garbage can. Fill it three-quarters of the way with leaves. Put the string trimmer in, turn it on and move it through the layers of leaves. Be sure to wear eye and ear protection.
3. Make Leaf Mold
Leaf mold is simply wet leaves that have decomposed into a rich, black, soil-like substance that makes a perfect mulch for plants. Pile the leaves in a spot where they’re out of the way and won’t blow away. Or make large (3- or 4-foot) circles of chicken wire, 3 feet high, and pile the leaves in them. Wet the leaves as you go so they’ll rot. Turning the pile a few times during the winter will accelerate the process.
4. Mix Leaves — Shredded or Not — Into a Compost Pile Now, Where They’ll Break Down Over Winter
Even better: Stockpile dried leaves, in garbage bags or piled in that out-of-the-way place, for summer. In warm weather there’s an abundance of succulent green material (nitrogen) for your compost pile. But to keep the composting process aerobically working, and not rotting, it needs lots of “browns” (carbon), in the form of dried material.
5. Protect Outdoor Potted Plants
When the weather turns cold and potted plants (the hardy ones, not houseplants or tropicals, which must be brought indoors) go dormant, pick a sheltered place on the north, west or east side of your house. Cluster the pots together against the house, ideally beneath an overhang. Pile dried leaves over, under and between the entire grouping of pots.
If the area is windy, corral the pots with chicken wire so the leaves won’t blow away. Pile the leaves inches deep, covering the pot and as much of the plant as possible. Under this insulating blanket, both plants and pots should come through the winter just fine. With this method, even terra-cotta pots can stay outdoors, as long as water can’t get into them and freeze.
