  • How do I stop my peach tree leaves from curling?

    Created by aartivarma on May 22, 2018 at 10:14 am

    Hello,

    I have a peach tree that I just planted. The leaves have been turning yellow and have mottled red dots on them. The branches also have these reddish colorations. I would send a picture but I’m not sure where to attach it. Do I need to treat it with a fungicide? Am I watering it too much? Please help!

    Hello –

    It sounds to me like your young trees have peach leaf curl. Symptoms appears in spring as reddish areas on developing leaves. These areas become thick and puckered causing leaves to curl and distort. When severe, leaf curl can substantially reduce fruit production.

    To treat this fungal disease we recommend the following steps.

    1.) Leaf curl can be controlled by applying sulfur or copper-based fungicides that are labeled for use on peaches and nectarines. Spray the entire tree after 90% of the leaves have dropped in the fall and again in the early spring, just before the buds open. For best results, trees should be sprayed to the point of runoff or until they start dripping.

    2.) Containing copper and pyrethrins, Bonide® Garden Dust is a safe, one-step control for many insect attacks and fungal problems. For best results, cover both the tops and undersides of leaves with a thin uniform film or dust. Depending on foliage density, 10 oz will cover 625 sq ft. Repeat applications every 7-10 days, as needed.

    3.) Keep the ground beneath the trees raked up and clean, especially during winter months.

    4.) Prune and destroy infected plant parts as they appear.

    5.) If disease problems are severe, maintain tree health and vigor by cutting back more fruit than normal, watering regularly (avoiding wetting the leaves if possible) and apply an organic fertilizers high in nitrogen.

    Hope it helps!
