While winter is around the corner, warmer spring weather is just a few months away. If you’ve been thinking of starting a backyard garden, now is the time to get the soil prepared. Rake mounds of dead leaves over the area of lawn you plan to garden. Thick layers of fall leaves left in place over the cold winter months will kill the grass that’s under the leaves and degrade into beneficial mulch. In the spring, flip the soil with the decomposed leaves, and it’ll add organic matter and nutrients to the soil.
