From: Austin, TX
Region: Southwest
Topic: Pruning, Seasonal Tasks, Herbs/Forbs
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.
