roses....
They are correct, it is best to transplant during dormancy. And to my knowledge,
roses aren't the best of container
plants...mainly due to water issues.
roses can't tolerate water that retains a lot of water, so my advice would be this...
1. Get a potting soil
2. Add sand to your potting soil to help it drain better.
3. Mix some
plant food for
roses into your soil and
plant the
roses when they aren't blooming.
Genrerally, if you nurture them well, and make sure they don't get over watered they should fair fairly well as long as they are getting plenty of the sun that they love so much.
Oh, and you can feed them some diluted beer every couple of weeks to help promote prolifient blooms. I don't know why...but all of my
roses LOVED beer!
