ScarletRose:
What kind of roses did you buy?
Scarlet you can probably plant roses if the ground is pliable and warm. Make sure they are sheltered by a wall or an arbor if you wish them to live. Roses grow very slowly, especially tea roses, and are extremely delicate. The PH and water has to be perfect. They are victims of fungus and bugs.
May I recommend: a CLEMATIS! In place of roses you'll get so much more beauty with way less effort.
