Organic spray for Apple trees
Can anybody recommend an organic spray for apple trees with a schedule? I maintain orchard bees so that is a concern also. The neighbors on both side of me each have a huge standard apple tree witch is not pruned or maintained in any way. They are havens for insects so I must spray often. I try to adhere to organic principals in my garden but if I want any useable apples I must spray. Any help would be appreciated.
