yellow stem on young apples, then fruit falls off tree
Young apples (red delicious and Gala) are developing a yellow stem and fall from tree. Young fruit is 3/8 inch in diameter. I have a drip watering system and water M-W-F for 30 mins. Rockrimmon Subdivision in Colorado Springs (6650 feet altitude). Is this a mineral defficiency?
El Paso County Colorado trees and shrubs
Young apple stems turn yellow and fall from the tree.
I called Michigan State Univ. Extension and found 2 reasons: 1. inadequate pollinator tree in which case the young apples will not have seeds. and 2. Seven insecticide causes young apples to drop --- I am GUILTY; THE YOUNG FRUIT WILL HAVE SEEDS IN THIS CASE.
Thank you for the follow-up. It is obvious to me that you are very knowledgeable about fruit trees. I applaud your efforts. I think successfully growing trees (other than natives) in our area is difficult.
