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: Pruning for Spring
Answered by: Joe Marcus

QUESTION:

When should I cut back (and how far should I cut back) the following plants in order to promote growth in the spring: Salvia gregii, Salvia leucantha, Ruellia (Mexican petunia), Plumbago, Skullcap, Fatsia, and Mexican Heather?

ANSWER:

All of the plants listed may be pruned back now (mid-winter) by 1/3 to 1/2 to promote healthier new growth and more compact habit. Try not to cut them back to single stems.
