Fruit Trees And Spraying
Monday, February 11th, 2008In Winter, once leaves have dropped, fruit trees should be sprayed three times with dormant oil and fungicide (lime sulfur or copper sulfate) to control fungal diseases and insect infestation.This week marks with Valentine’s Day when the third and last spray should ideally happen (first is around Thanksgiving, second around Christmas).
This is really important for peaches and nectarines which are very susceptible to Peach Leaf Curl, especially in a wet winter.
Remember that apricots can’t be sprayed with lime sulfur (use copper sulfate instead).
Also, sprays should be allowed to dry on the bark, so don’t spray if rain is expected shortly thereafter.
Soon, it will be too late as you shouldn’t spray your trees once their swollen buds have bloomed.
I just sprayed my 50 trees and I will be glad I did this coming Spring!
