Honeysuckle plants have failed to flower

Need more information; what type of Lonicera are they, climbing ones? In pots or in the ground? How long have you had the plants? Have you pruned them at all, and if so how much and when?

They are climbers and have always been in pots. I have had them for about 5 years and have never seen the best of them so for this year I put them in taller pots with fresh compost and pruned them right back in the spring.

Minimum size of containers should be 18 inches deep by the same wide. If you cut them right down in the spring, that might explain why you got no flowers at all - always best to remove any dead wood and reduce the rest by a third to two thirds if you want flowers the same year. It has to be said they do better in the ground, but what have you been feeding with since repotting? Anything? Nothing?

That's helpful, thanks. I fed them with Phostrogen which is a general purpose feed, once a month. Perhaps I need to feed them weekly?

Weekly or fortnightly during summer would help.

Ok thanks a lot.
