I bought a Potenilla Katherine Dykes from Home Depot about a month ago. Now the leaves and branches seem to be turning brown, especially at the bottom. At the time of purchase, it had yellow flowers
and green leaves, now there are 2 dead yellow flowers
and it is looking very brown. Is it going to die? If so, I will return it to Home Depot and get my money back. They have a year guarantee for all their plants
. It has lots of sun and I water it all the time. I also noticed that it originally was much larger and as I rub off the dead leaves it seems to be shrinking. Any ideas??
