Title: What is considered mid-winter in Austin, TX
Answered by: Nan Hampton
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.
The original question came from someone living in Austin, Texas and Mr. Smarty Plants considers that mid-winter in Austin would be January and February. This would be after the fall growing season and before the new spring growing season begins. The answer (which is dated January 21, 2007) does say "now (mid-winter)". The date (January 21, 2007) is the date the question was answered and posted.
