Q. Who is Mr. Smarty Plants?

A: There are those who suspect Wildflower Center volunteers are the culpable and capable culprits. Yet, others think staff members play some, albeit small, role. You can torture us with your plant questions, but we will never reveal the Green Guru's secret identity.

Title: Removing Persimmon plants from the base of Live oaks
Answered by: Guy Thompson

QUESTION:

I live in Bastrop county and have hundreds of Texas wild persimmons at the base of my huge oak trees. Should I cut some of them? I am worried they are taking up water my oaks need. I like them but don't want them to damage my iaks. thanks

ANSWER:

Diospyros texana (Texas persimmon) is a tough native that can survive drought very well.  The large number that you seem to have growing under your oaks (Quercus fusiformis (Escarpment live oak),I presume), could provide a serious drain on the water that otherwise would be available to the oaks. I would advise you to remove all of these persimmons except for a few that you might like to keep for esthetic reasons.  A further step that would help the oaks would be to cover the area around the base of the trees out as far as the drip-line with mulch about two inches deep.  The mulch reduces loss of soil moisture due to evaporation.  Live oaks are themselves quite drought-resistant. Unless our drought becomes much more prolonged they should survive with little damage.
