Apple trees

Scab, perhaps? Our Red Falstaff gets it every year, though not as bad as that. Not much you can do about it if there are other susceptible apple trees in gardens near you. The most you can do is get rid of all the leaves and fruit which drop, and hope for a dry summer. I think late varieties are more likely to get it badly since the fungus has longer to take effect. Our apples have had barely any codling moth damage for the past few years, I think the increased number of predatory insects in the garden has really helped.
