…literally! If you have a garden in the ground or in raised beds you should consider sowing a restorative ground cover or layering the surface with thick mulch for the seasons in which your garden is dormant. For example, this year I grew acorn squash, which choked out the turf over which the vines grew. This was actually a desired effect so that I had less grass to mow. Now that the harvest is complete and the vines removed to the compost pile, there are bare patches of earth in my yard.
Bare patches of earth are bad for the microbiome in the soil and are dead zones for the precipitation cycle. They can also allow for a greater chance of disease or pests when it comes time to sow next year’s garden. Plus they’re ugly! In order to restore the depleted soil and maintain a healthy microbiome, you can apply a thick layer of mulch or, my preference, plant a beneficial cover crop.
I did the latter, and the cover crop I chose is Dutch mini white clover. Clover fixes nitrogen in the soil, which is a nutrient that squash (and all plants) consume a ton of while they’re growing. I chose the engineered “mini” clover because it will never grow tall enough to want mowing, and if you’ve noticed there’s a trend in my gardening style which is to eventually never need to mow my yard ever again.
My clover has started to germinate and it is developing very well!
I made a mistake when sowing and watered before I had pressed the seeds into the soil. This caused some of them to wash off the big bare patch of hard, dry earth and collect at the edge of the turf. But that’s okay! That just means I get to sow more clover seed!
You can leave your cover crop for just the winter if you want and then dig or till it into the soil when you plant. Gardens love clover though! It helps to prevent the soil from drying out between your other plants, and like I mentioned it fixes nitrogen. This means it draws nitrogen from the air and the minerals of the earth and makes it available for consumption in the soil. All plants need nitrogen but few fix it, which makes clover extra special. Next time you see some clover in your yard, thank it!
