We started out buying 25 or so already grown from another nursery. Now, we plant about 250 bare root from JP every year and sell all or nearly all. Our JP rep told us our roses are in the top 10% of all his dealers and he has 6-8 southern states along the eastern seaboard.
This is a tough area for roses. Hot and humid. Not a good combo.
Before I moved from our last home, I had so many roses I couldn't keep count. I miss my old garden so much. I've planted quite a few since we moved here. Love all roses but particularly fond of HTs.
We have humid summers too. I faithfully spray. The deer are a bit of a problem. They like them as much as I do. ;)
