Clematis plant being eaten!
I have a Clematis Arabella planted in the ground and growing up towards a trellis fixed to a fence. The new growth looked very healthy until I noticed several leaves were being nibbled. Today I noticed that the growing tips on each part of the plant had been munched off completely. Each part of the plant is about 12" high (attached to canes) so is it likely to be slugs or snails? Sadly the same happened last year when the plant was stripped of all leaves. I have 2 other clematis plants in pots not far away from Arabella that are doing fine. Any ideas or suggestions to halt another flowerless summer?
