Don't plant the roses too close to the foot of the wall. Plant them a good eighteen inches to two feet away and train them back to the wall. Prepare the soil well, digging in plenty of organic matter.
Also, please don't think that because the roses are in the ground they won't need watering.
Walls create what is known as a 'rain shadow' which is drier than the area around it, and also walls act as sponges and soak up moisture from the soil. Your roses will need looking after, but you will be well rewarded. Enjoy
