Pieris Katsura compact shrub
I bought a Pieris Katsura shrub about 2 weeks ago from a garden centre. We paid £44.99 for it so it was well established with lots of flowers. But the past few day's I have notices that the flower's look as if they are dying. There are a few new red leaf shoots, but some other leaves look brown as if they are dying too. Is this normal?
I have tried to look on the internet but all it say's is where to plant, and how big they grow etc.
Any ideas why this is happening?
Thanks in advance for your responcses.
