Inconsistent watering practices may cause apple leaves to shrivel up, or your tree could have a fungal disease. The most common in your area is apple scab. The fungus overwinters on dead leaves and fallen fruit, so first order of business is to keep debris cleaned up in the garden. The key to successfully controlling scab is to apply fungicides early in the season. Spray early and thoroughly and you'll protect new growth. Use a wettable sulfur solution or a Bordeaux (lime-sulfur) spray as soon as the cluster buds develop, again at pre-pink, pink, and after petals fall. Avoid spraying when trees are in full bloom.
