My Daphne seems to be struggling. This year I haven't had many flowers and the leaves are discoloured and have brown spots underneath. The leaves have been looking like this for a few years and I've tried spraying with a pest oil but only semi-regularly. This morning I decided to remove all the affected leaves, there is quite a lot of new, unaffected growth. Was this the right thing to do? Does anyone have a diagnosis or help about how to manage this?
Photos of the plant is after I removed all the affected leaves.
