Best Ways to Protect Your Soil
by Sandy Swegel
Winter winds will come and steal your soil away if you’re not careful. If you value your earthworms and the compost that naturally forms on top of your soil under plants, figure out a way to cover your soil this winter. Here, in Colorado, we can have 100 mile-an-hour winds in January, so we take this seriously. We also have to take seriously the fact that anything we use to cover the soil needs to be securely attached to the ground.
Here are some of the ways I’ve covered garden soil:
These require the most planning and the most work in Spring of tilling the crops in….but
they also provide the most benefit to the soil by adding organic matter and nutrients. NOW is the time to get your winter rye or clover planted so it has time to grow before the soil gets too cold.
Leaves are my favorites because they become leaf mold and can be dug into the soil in Spring. In Fall, I spread as many leaves as I can all over perennial beds and over the open vegetable bed. In the perennial beds, the other plants tend to help keep the wind from whisking all the leaves away. Out in the open vegetable bed, I spread 6 – 12 inches (if you have that many) of leaves on top of the soil Then I put dozens of heavy plastic bags filled with leaves the neighbors have tidily vacuumed and mulched up on top to hold the loose leaves down. If the bags aren’t heavy, I put rocks on top of them. Not a pretty winter garden….but the earthworms thrive in the moisture and warmth under the plastic bags. In Spring, I can spread the leaves in the bag as a mulch on the garden.
Newspaper by itself blows away too easily, but cardboard, if secured by rocks and bricks, does a good job of holding in soil and moisture. Make sure the soil is watered before you put the cardboard down. A layer of leaves and or newspaper under the cardboard will give the worms and microbes something to eat.
Plant a wildflower meadow.
Do you have an area of your yard that you don’t really need for vegetables or perennials? Keep the soil healthy and the garden beautiful by seeding a wildflower meadow. Fall is an excellent time to plant a mix of wildflowers or even a mix with grasses and wildflowers that will be beautiful for years.
However you decide to protect your garden….you’ve worked hard to enrich the soil and keep the worms and microbes happy. Help them to stay home and not blow off in the wind or desiccate in the winter sun.
