Sickly Bay Tree
I have sucessfully had a bay tree in a large pot for a few years. I ensure that I top dress each spring and give it the occasional feed when required. Its in a sunny, but sheltered position.
In previous years its had the odd bit of sooty mould and the occasional brown leaf but overall has been really helathy, until now....
I noticed that there are black spots on the leaves of one side of the plant (but its not sooty mould) with a couple of the branches where the leaves have gone brown and curled up completely. The brown spots seem to be spreading across the plant.
Any ideas? In this hot weather I have been watering it, but only every couple of days and am carefuly not to overwater as I know that bays dont like that. I am planning to prune the worst affected branches off but reluctant to give it a hatchet job as its just got to a really nice shape
