One of the most important things to know before starting or buying new plants for your outdoor space is what type of soil you are working with. Failure to do so can lead to poor growing conditions, resulting in costly and unsightly mistake. Severity can range from yellowing leaves to full blown plant death from root rot.
The mountainous southeastern to mid-Atlantic region of the United States, a/k/a Appalachia, is heavily composed of red clay soil, officially known as Ultisol. This type of soil can also be found in regions of Africa, Asia, and South America. While full of nutrients, it also holds water a little too well. This can be a problem for plants that need adequate drainage. The overflow can result in fungi and disease.
To prevent a build-up of excess moisture, it is recommended to put some sort of chunky material in the soil to provide proper drainage. We like to use pine bark soil conditioner 50/50. This allows space for oxygen and nutrients to reach the roots of your plant.
Technically, Peat Moss would also work if done correctly, but has come under increased scrutiny as of late for not being an environmentally friendly option.
With conditioner of choice in hand, dig a new hole for your plant about twice as deep and wide as the root ball and set the red clay to the side.
Once your new plant is in place, take the freshly dug clay material and create a 50/50 mixture with your conditioner and re-add it to the hole.
Follow this simple step and you will have increased your chances of being a successful red clay gardener by eliminating one of the most common problems associated with this soil – drainage.
