Title: Plants beneath native bald cypress trees in Thibodaux LA
Answered by: Barbara Medford

QUESTION:

I have a bed that needs to be revamped and it has two beautiful 18 year old Bald cypress trees. I would like to work the soil and plant some appropriate shade tolerant plants. How do I work the soil with the roots and knees, without hurting the trees?

ANSWER:

To be perfectly honest with you, we wouldn't. The "knees" develop mostly in poorly drained situations, since the tree is adapted to being an aquatic plant. The knees are useful in an exchange of gases and take in oxygen in a low-oxygen environment. This tree can live to be BIG and OLD, and like the gorilla in the house, needs to be able to put its roots anywhere it wants to. In an area like Lafourche Parish, where you are in Louisiana, two very important functions of the roots on a Taxodium distichum (bald cypress) are that the tree is not susceptible to suffocation, so it can withstand flooding, and also for support. This tree is rarely blown over, even in hurricanes. We would recommend mulching the bed where the bald cypresses are, and going farther out to plant grasses or garden plants. Besides being very utilitarian, we think the knees on the trees are an interesting feature of a wonderful tree.
