I've not grown a clematis before and have been given one by my son and taken cuttings from others I liked the look of last summer.
They are growing like mad but I cannot see any flower buds yet.
My son says to put some potash on them????
I don't know the varieties of either of the plants, anyone any ideas, thanks
Clematis often take a good long time to get mature enough for flowering. If you know the type and/or name of the clematis that might give an idea as to which time of year it might flower when it does get big enough. There are clematis flowering here from early spring to well into the autumn, following one another according to their types. They are hungry plants and are one of the few things for which I buy specialist feed. This is available at most garden suppliers. They need their feet in shade, and their heads in the sunshine (when we have some). Give it time to grow a nice strong set of roots, then a good framework of leaves, and then it will start flowering in due course will hopefully do so for many years to come.
Four of my six clematis are not flowering this year. Previously they have all done well what can I do to resolve this?
Feed with specialist clematis food which is granular and slow release. Give an instant tonic of liquid tomato food and check you are using the correct pruning regime for each clematis variety.
