I have a blaze climber and some type of pink rose bush (not shrub). Usually they both have an abundant amount of roses. The bush will last most of the spring thru to the middle summer. Then lose the blooms and rebloom in early fall until frost. The climber is only three years old and had just really bloomed last year. But the blooms were full and lasted quite a long time. The bloomed again later in the summer.

This year I only had a few blooms in only parts of the bush and the climber bloomed nicely but died only a few weeks. There has not been any reblooms as of yet which should have happend already.

I have two questions that may be the cause and I need your expert confirmation to these.

1. I usually have morning glories that grow on my roses, not alot they actually accent the bush quite nicely and had not until this year caused me any concern. However they grew for the first time on my blaze and they grew at least 6

The morning glories may have been a reason for less blooms on the climber. Roses need 4 things to bloom well: full sun, adequate soil moisture, fertilizer to keep vigor strong, and good foliage health. You could fertilize a little more I think. Also if any pests or diseases damage the foliage this can weaken the bush and reduce blooming.

I suggest you cut them back by about 1/4 and then fertilize them now and again in 2 and 4 weeks. I think you should see a good bloom in the fall.

Thanks for the question. Please stop in again soon!
