Garden Obstacles: Clayey Soil

Updated: Jan 25, 2022

It doesn't happen often on Long Island but there are some areas with pockets of soil with clay in them. It's usually still well draining because our natural soil is a sandy loam. Improve the texture of your clay soil and you’ll be able to plant even more species. Amend it by mixing in organic matter, such as mulched leaves and compost. Position plants so the top of the crown or root ball is slightly above the top of the soil (about 1"). This will help prevent their suffocating in the event the clay stays too soggy even after you’ve improved its texture. Most of these plants take full sun to partial shade but there are a few that will take shade.
