The compact nature of clay soil makes it difficult for plant roots to spread through. Thus, you need to tread carefully while working with clay soil. That’s why I always recommend natural options. One type of organic option useful for this process is a mushroom compost. This is the leftover of mushrooms that were grown in. Moreover, this article presents itself as a complete guide with vital steps you should take to improve the clay soil.
Amend the soil in the spring or fall when the ground is not too wet. If you grab a handful of soil and ball it up, it should be slightly crumbly, not soggy.
Remove an 8-inch layer of dirt from the area you plan to amend. Break up the soil with a tiller and remove the dirt with a shovel. Set it aside for later.
Spread an even layer of mushroom compost over the area you exposed when you removed the soil. Start with a 2-inch layer of compost and till or dig it about 8 inches into the soil.
Add a new layer of compost and repeat if you wish to further condition the soil. You can add as much or as little mushroom compost to the soil as you wish until the soil is the consistency you want. From one part compost to three parts soil to one part compost to one part soil is a good mix for plant growth.
Mix the soil you removed in the first step with the desired percentage of mushroom compost and fill in over the composted area. Heavy clay soils need more conditioning than clay mixed with loam.
