Can I successfully transplant phlox?
The best time to transplant most perennials is in the fall or spring. If you can wait until then that would be best. If however you must move your phlox, make sure to dig as large a root ball as possible. You should have a hole already dug in the new location so that the roots don’t get a chance to dry out. Once the plant has been moved, give it a through soaking with water containing 5-15-5 fertilizer (follow directions on package) . It is a good idea to give it a watering every day or so if there is no rain in the forecast until you see some signs of new growth.
