Q. I need your advice on tree roses, please. I'm a recent transplant from the Denver area. I have always wanted to grow tree roses but because of Denver's winters I never tried to grow them there. My all-time favorite rose is Double Delight. Do you think it does well as a tree?
A. I went ahead and attached a copy of roses that do well in our desert climate, a publication from Weeks Roses. As you can see, Double Delight is a very good hybrid tea for our climate. It should also do well as a tree rose. Roses will do best if you do not plant them near a hot wall such as South or West facing.
Having said that, the advantage of putting them in this exposure is that you have a greater chance of getting blooms all winter long in these locations provided you provide some protection from winter wind. Winter winds primarily come from the north and northwest here. These directions may change in an urban setting where winds are diverted and channel between buildings.
If you can, try to create a microclimate for them that will stay warm in the winter but provide some late afternoon shade in the summer. The disadvantage of that exposure is the amount of heat generated in midsummer and the stress which accompanies it.
