What sort of site do you have it in joanna? They prefer a bit of shade and some moisture to do their best, and don't care for alkaline soil, but if it's only recently that it's looking poorly it may be pests of some kind or a different reason. I assume you fed and watered it well initially when you transplanted it, but it may have needed a bit of pruning if it was big - that can cause stress when the plant is getting settled in.
Can you post a pic? That will help with more advice from people.
