If your soil is even average fertility and you added compost when you transplanted, you likely don't need to fertilize. A mulch of something organic to cool roots and conserve moisture this year would probably be of more benefit.

My own shrubs are never fertilized (they've never indicated a need) - but are top dressed with compost each Spring. It would help us in answering questions too if you added your garden zone to your sign in page (i.e. Z8 WA)...your climate may make a difference in suggestions you could be given.

Thanks for the info, it is very helpful. I will go to my page and add my zone. Thanks!
