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: Sticky material dripping from tree in Austin
Answered by: Barbara Medford


The tree in my backyard is dripping what I surmise is sap - a thick,fdrake1@ sticky substance in July. What kind of tree is it and is there anything one can do prevent this from happening? Thank you for your help!


Please read this previous answer on aphids. We have no idea what your tree is, aphids attack everything and they seem to be unusually bad this year in Austin.
