Title: When should salvia greggii be pruned from Austin
Answered by: Barbara Medford

QUESTION:

Should salvia greggii be pruned in fall/winter? I thought I read onsite that all woody perennials should be left untouched or pruned to 6 inches. Does this apply to salvia greggii?

ANSWER:

If you follow this plant link, Salvia greggii (Autumn sage), to our webpage on that plant, you will find this paragraph:

"Maintenance: Trim or pinch tips continuously for nonstop blooming. In early spring, you may wish to prune it a third to halfway back to produce thicker, more compact foliage and a shorter flowering plant. Pruning may delay flowering for several weeks, but it is important if you want to prevent leggy plants. On the other hand, if you want to encourage the plant to assume its maximum natural shape, however tall, only pick-prune."

This member of the Mr. Smarty Plants Team has always recommended pruning perennials back in late Fall. We usually pruned back to about 6 inches tall, so you knew where the plant was and would not pull out the new growth down at the base when it appeared in Spring, thinking it was a weed. Any time we link you to a page in our Native Plant Database, we suggest you read the whole page to find out other useful facts about the culture of that plant.
