Black marks on Buddleja leaves
Bright star Posts: 1,152
I bought and planted a buddleja buzz indigo about 2 weeks ago. Today I noticed that some of the leaves have black marks on them. I can't see any pests on the plant so I'm wondering if it could be a fungal problem and if it is will I be able to use a regular fungicide spray to treat it, many thanks.
Life's tragedy is that we get old too soon and wise too late.
I'd pull the affected leaves off and throw them in the bin (not on the compost). Sorry I can't help with what it is but this is what I do with anything that makes me uncomfortable.
It might be scorch, if the plant was watered when the sun was shining on it. But Cloggie's method will work whatever the problem is! I wouldn't use a fungicide spray, personally - they seem to be having a bad effect on bees.
If you feed the soil (with organic matter) and keep the plant healthy, it'll probably grow out of it if it is "a thing".
