How do I keep my climbing rose bushes blooming?

It sounds as you are giving your roses plenty of attention and care. Great job!

Are you watering them as well?

One thing that comes to mind is during the summer when it is hot and dry, the plant's energy goes to the roots and stem, which are needed for the life of the plant, the blooms become secondary to the plant staying alive.

When temps cool in the fall, they bloom again because they are out of survival mode.

Hope this makes sense. Best to you.

They bloom in the fall because your grounds are too hot.

Please do Keep in mind that the plant does not go inside to relax in the Air Conditioning...You do.

To resolve hot grounds, You need to not only water and fertilize certain plants, [Not solely rose bushes, but also Cucumbers, brocolli, Cauliflower include as well as most melons, pumpkins and squashes], you need to Ice them too [and per PH Necessity, actually get some crushed or powdered bismuth, to add to the soil].

Especially for those plants that bloom only in colder water temperatures, you need Ice.

Very likely it is the wrong Species for your Zone.

To fix this, you need to either:

A. Get rid of the bush by trading it for something suitable for your Zone.

B. Add Ice to your watering pot, or

C. Just make big blocks of ice, [freeze water in those leftover potato salad containers] to place ice out on the extremely hot days.

D. Both C and B.

I know this works.

Ice can be the difference between Zone 8 and Zone 3, and relies the species of the rose, [or any plant].

This especially applies if the previous owner planted it, after moving there from say: Vermont to Arizona.

1. Make sure it's right for your zone. (mine is North Texas--really hot). Also get good quality bushes.
2. Fertilize early spring, early summer, fall
3. Deadhead. Remove the spent blooms. That makes a huge difference.
4. Water appropriately but not too much. I have never used ice. Can't see how that would help.
5. Expect far less blooms in the hottest part of the summer but it will pick up again as the weather cools.
6. Get an organic professional to control pests, scale, etc.

Get a Jerry Baker book on gardening. He offers tips and solutions for hundreds of things. Roses: get overripe (icky) bananas and a shovel. Go out to your rose bushes and push the shovel down in the soil about 4 or 5 inches. You do not have to remove the soil. Just lean the shovel forward to produce a sliver of a hole. Drop in the banana (peel and all), remove the shovel, and stomp on the dirt to repack it down. It help squash the banana in the soil.

I usually do a couple for each rose bush (on each side). It is unbelievable what that little blast of rotten banana can do for one of the most beautiful flowers on earth. Good luck

This banana idea sounds interesting. I will give it a try. Thanks.

They're following the natural course of their bloom - they don't bloom continually. Plants, like people, need to rest. Blooms are their reproduction cycle and they need to rest in between blooms :)
