I've been reading conflicting information. Some expertthat's that clematis are greedy plants and thrive on feeding. Others say don't feed once in flower. What do people think? I have number of plants: Arabella, Rebecca, Abilene, Guernsey Cream. The latter is just coming to the end of a fantastic flowering period. It may flower again.....what do people do to encourage this to happen?
Meant to write: some experts say that.......
Mine are in 3 huge pots, climbing up a trellis. I top dress and add Growmore in the spring. When they start to actively grow I give a couple of liquid feeds over a month. Once in bud they get a tomato feed and then that's it, other than plenty of water. They are thirsty but terracotta pots do dry out quickly.
I mulch with FYM in the autumn, Fish, Blood & Bone in the spring, and then some more feed when they're flowering, to encourage a second flush.
I have a few Group 3 types in pots (Abilene is one) - because they are in pots I use those slow release pellets every year about April and that keeps them fed all season.
For the ones in the ground I use a Vitax Clematis feed in about April time too.
Thanks for the advice, everyone. Any ideas about my Guernsey Cream? I don't know whether to prune it now, to encourage a later pruning.
