Heavy disease pressure leads to premature leaf drop. Damaged leaves become curled and yellowish with lesions, eventually turning brown. This primary infection produces olive colored spots on leaves.Īs the fungus grows on the leaves, new spores are produced starting a secondary infection of leaves and fruit. ![]() Spores from these old leaves are carried on air currents to new developing leaves. Scab-infected leaves from the previous season, left on the ground around the tree are the source of fungal spores that can infect the crabapple the next spring.

Once the tree is straight and located as desired, cut and remove twine.Backfill ½ of the hole with soil and completely saturate the soil with water.Place fertilizer packets into the bottom of the hole (if purchased).If necessary, add soil under the ball so the root flair is exposed. This root flair should show when the tree is planted.
