Salvia Greggii - how long before time for replacement?
I have my first set of Salvia Greggii. I know that there has been discussion about pruning to where the first new leaf growth appears...but I need more info please.
In So. Calif...which month(s) should I trim?
If it is only to the new growth...does that mean I trim more often to keep it in a certain shape or size?
How many years before I should pull it out and replace?
What is the average size?
