Trees and Shrubs For Midwestern Clay Soils

Most of the Midwestern area is comprised of clay soils. Never fear! This is a much better situation to have than sandy soils. Clay soils maintain more minerals and moisture than other soils.

Sometimes clay soils can be bad, such as in conditions where there are more problems than just the soil. If while digging in the soil, it looks blueish-black and smells kinda off, this is because of poor drainage and the smell is from rotting organisms. The area should be assessed for drainage problems before anything else is done.

If the clay is a redish-orange, this is perfect as the soil is holding all the minerals plants crave.

With regards to planting woody plants, be sure to plant these correctly and never lower than the top of the roots of the rootball. If you’re at all concerned about the clay content of your soil, plant you woody plant a bit higher. Trust me, they will love you for it!!

Perennials for Midwestern Clay Soils

Most of the Midwestern area is comprised of clay soils. Never fear! This is a much better situation to have than sandy soils. Clay soils maintain more minerals and moisture than other soils.

Sometimes clay soils can be bad, such as in conditions where there are more problems than just the soil. If while digging in the soil, it looks blueish-black and smells kinda off, this is because of poor drainage and the smell is from rotting organisms. The area should be assessed for drainage problems before anything else is done.

If the clay is a redish-orange, this is perfect as the soil is holding all the minerals plants crave.

The soil should be mixed with a fair amount of compost to help perennials get a good start. If the soil is very compacted, some sand can be mixed it also. Be sure to surround the perennial bed with leaf compost to aid in nutrients getting to the roots and all the other benefits mulch does for plants.
