The Q&A Archives: Pruning Perennials

Question: We have a number of Indigo Spires that we planted in our flower beds last year. They have become amazons! They are 4-5' high and crowding out other plants. We want to transplant them to another area, but it isn't ready yet. Will they survive a pruning to control their size now? If so, when is the best time to transplant them? Currently they are in a sunny location (until late afternoon), and we want to move them to a partially shady location. Will that work?


Answer: Melinda,

You can shear them a back and as long as you leave some foliage on the plants they will be fine. The best time to transplant them is in Oct or Nov when the brunt of the hot weather has passed and fall is well underway. Partial shade will work if it is part sun with very bright shade. In a lot of shade they won't bloom very well. You may also want to look for the variety Mystic Spires with is just like Indigo Spires but only reaches about 2 1/2 feet.

Thanks for the question. Please stop in again soon!
