Yellowing clematis leaves
Good Morning All I’ve got 2 clematis in pots which usually do very well. They’re Princess Diana and Pink Fantasy. Now the leaves look a bit yellow at the edges. I put fertiliser (blood fish and bone) on in early Spring might this have caused the problem. Any ideas welcome please

Could be a magnesium deficiency, try a tablespoon of Epsom salts dissolved in a gallon of water & make sure the leaves get wet when you water

Whether it's a deficiency or not; I would suggest that you would be better off by planting a little deeper in the ground. They like their heads in the sun and their roots in the shade. As you water regularly in the hot summer months, you will quickly wash away the nutrients. Otherwise the alternative is to feed with slow-release granules.

How long have they been in the same pots? If it's longer than 2 or 3 years, they probably need larger containers, or at least deeper ones.

Thank you all very much. I’ll try all the suggestions - do you think it would help to put more fresh compost in the top of the pots and try to make sure the pots themselves are in the shade?

The pots they're currently in don't look as if there's room to add an extra couple of inches of fresh potting compost - they will do better in pots 18 inches to 2 feet deep.
