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: Cutting back perennials from Austin
Answered by: Barbara Medford

QUESTION:

When is it time to cut back native plants; salvia;copper canyon daisy; verbena, etc?

ANSWER:

Most Texas perennial flowering plants need some cutting back when they have dropped their leaves. Many can actually be cut to the ground, as they are going to come back from the roots, but we like to leave a few 6-inch stalks standing up so we know that's a plant we planted, and not a weed that needs to be yanked. Always clean up around your plants, taking away dropped leaves and stems, to help prevent mildew, disease and insect damage.
