Like I said, clematis are greedy. Bonemeal given in autumn and worked in round the base of the plant will help roots over winter and thus betetr above ground shoots next srping and summer.. Blood fish and bone is a balanced general fertiliser that will help growth of the whole plant. Clematis food is sepcifically balanced to help flower production and tomato food is specifically balanced to help with flower and fruit production so I will use all four feeds at different stages of growth because I want good growth, good flowers and good fluffy seedheads on the early group 1 flowerers such as Red Robin and then a repeat season of flowering in May/june and then late summer from the early hybrids (group 2s) and a long season of flowers followed by seedheads from the summer flowering group 3s as well as perfume from the ones that have that too.
The same feeding regime will be good for roses and any other climber or shrub from which you expect a high performance level.
