I planted a couple of comice pear trees 3 years ago when we move into this house and each year the leaves have had the same black mould and gradually the trees have died back and now are about 2/3 the origional size. Also have the same blackening of leaves on a crab apple that was OK for a couple of years ( they are usually pretty robust so was v surprised) and my plum? My garden is on very heavy clay and is very wet so assuming this is not helping so had replanted in slightly raised beds to try to get them off to a better start; and of course sprayed last year.
I wonder if anyone can tel me if there is any point in spraying this late in the season. for the first time ever my crab apple seems to have set no fruit. All the fruit trees I have in pots are fine so am assuming it must be something to do with the ground conditions? What kind of soil do you have?
