Thanksgiving, Christmas and Valentines Day are the three dates to remember for dormant spray applications on your fruit trees, The first application should be done this week or very soon after. As soon as the rain stops and the trees have lost their leaves. Use Liquicop mixed with Horticultural Oil or Neem Oil. Spray the entire tree. Spray all your deciduous fruit trees in your orchard to prevent leaf curl, reduce the chance of fireblight and kill overwintering insects. Healthier trees will be the result next spring.
