Fruit Tree Dormant Care

Tip description

In winter, as your deciduous fruit tree goes dormant, you can do a few things to ensure a healthy and productive growing season next year. Thin or cut back branches to improve airflow and sunlight penetration. For pest and disease control, remove dead or damaged branches and mummified fruits from the tree. Dispose of diseased wood, fruit, and leaves from the ground.

If you've had major pest infestations on your fruit trees this year, now is a good time to use dormant oil sprays. These are used to reduce overwintering populations of insects. They work by smothering soft-bodied insects and eggs when applied at the proper times in the life cycles of the pests. Identify the issue you had this year, and choose the appropriate spray. Make sure to follow the instructions carefully as you apply it. See Winter Pest Management and Fruit Tree and Vine Care Calendar for more information.
