Sometimes it's nice for me to have timeline for cleaning out those 'spare' rooms. Until there's a deadline, there is always something more important!
These particular wild roses, often called dog rose locally, are quite impossible to get rid of. We also have some wild apothecary roses, with pink flowers and wonderful smell, that are a quite a bit more fragile. We started trying to cultivate some of them three years ago, and it's going VERY slowly.
Where I'm at, store bought roses are tough for the first couple years, but once they're well established, they are very resilient. I have some store bought tea roses out front that are starting to grow like the wild ones (we had hundreds of blooms on just two bushes!), but they've been in the ground about 10 years now.
Thanks for the good wishes, I'm heartily hoping this year goes better than last year!
