why have my climing roses stopped flowering this year they are fed and watered regularly?

Answer 1

Some years they do better than others. They probably got too much rain in July. Try not to take it personally.

Answer 2

Many of the older climbing varieties bloom on second-year canes. If those canes were acidentally pruned back ... then bloom production will be minimal. Climbing roses don't like pruning, so any heavy pruning is usually done only every three or four years.

Use a fertilizer that is higher in phosphorus than nitrogen, because "phosphorus promotes the root system and the blooms".

One trick to make climbing roses produce more bloom is to train them more laterally than vertically. When trained more horizontally, climbers will produce short spurs along their main stems or canes and these will produce blooms (very similar to practices used on apple or fruit trees to increase bloom and fruit-set).

If your rose bush was a repeat bloomer in the past, maybe this year something could be growing nearby that is now shading your rosebush. "They will bloom more and grow more dense and full when they receive at least 4-6 hours direct sun each day."

Here's a site that answers rose questions:
http://www.ext.nodak.edu/extnews/hortiscope/flowers/rose.htm
Q: "A producer planted a rose bush some years ago. The first two years it blossomed profusely. In the last two years, the buds have only opened partway. (Beach, N.D.)
A: It could be thrip activity. Look closely at the buds and peel the outer petals back to see if there is any evidence of feeding activity or the dirty bounders themselves. If not, then cut the stem off and check for borer activity. The stem should be hollow and empty, or if you are lucky, hollow with the culprit caught in the act! You know what to do then."

Q: I have a rose plant that for the past few years has not bloomed. I don't know its past history because I have only lived here the past two summers. The growth is very prolific but I have yet to have a single blossom. I have several other rose plants that are doing fine. Would you happen to know what the problem might be and how I can correct it? (E-mail reference)

A: From your description, it is probably growing from the rootstock only, so it will not produce a flower. I suggest digging it up and replacing it with a fresh plant.

Maybe your answer is in one of the answers from Ron Smith, Horticulturist, NDSU Extension Service
...in the last website mentioned above.

Good luck! Hope this is helpful.

Answer 3

Regularly dead head if possible to encourage new flowers, feed with high potash fertiliser for better blooms.
Climbing roses require minimum pruning, remove soft tip growth on leading shoots and shorten laterals to 2 buds; tie in replacement shoots, prune this way about March to end of Aprill, feed with liquid fertiliser in may, use high potash fertiliser early summer.

Answer 4

The simple truth is that Most climbers and ramblers only bloom once during the season. Some repeat bloom, but the repeat blooms tend to smaller and shorter lived. Next season your climber will put on another beautiful show for you, but may only bloom a bit more after that. Just remember not to prune your climber unless you need to.

Here is an article from David Austin Roses on how to prune climbing or rambling roses.

Answer 5

Next year try feeding them Banana peels, just bury the peels under the soil around the bush and you should get beautiful roses all summer.

Answer 6

Roses need high potash to keep them flowering

Answer 7

Do you have trouble with slugs and snails because they could have eaten all the buds.
