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.

Please forgive us, but Mr. Smarty Plants has been overwhelmed by a flood of mail and must take a break for awhile to catch up. We hope to be accepting new questions again soon. Thank you!

Title: Oak sap dripping on driveway in Austin
Answered by: Barbara Medford

QUESTION:

Why would oak sap be dripping on driveway at this time when other oaks the neighbors have are not.

ANSWER:

This is not a happy question; there are several things that could be causing this and none of them are good. Please read this previous Mr. Smarty Plants question. This question was referring to a different county. We recommend you contact:

Eric Beckers
Texas Forest Service Project Forester
8317 Cross Park Drive, Suite 425
Austin, TX 78754
512-339-3772

It is important that you get an expert to diagnose the problem as quickly as possible, before what it is has spread to other trees.
