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: Christmas decorations on a live oak in Montrose CA
Answered by: Barbara Medford


Is it OK to put Christmas lights and decorations on a live oak?


Sure. You do want to avoid putting any kind of damaged light string up, lest a spark cause a fire hazard. And you want to make sure the lights are certified for outdoor use, and are as cool-burning as possible.
