Q.Sour cherry
I would like to ask something about a 4 year old sour cherry that is about to flower. Every year it fruits after a certain period while still small like peas, even smaller, become yellow and fall down from the tree. In this situation, we lose 90% of yield. The neighboring sour cherry fruits with no issues! Thank You in advance for your answer.
Sour cherry trees mature between 3-5 years old so your tree just might not be old enough to fruit viably. Young fruit trees are more prone to overbear and can succumb to early fruit drop.
How healthy is the rest of the tree (leaves and branches)? Tell me about your watering and fertilizing practices. Are there any signs of insect pests? Did your tree suffer a frost or extreme cold at any point during the blossoming/fruiting processs?
