Non-bearing trees should make at least 18 inches of terminal growth and have good leaf color. Bearing trees should make 10 to 15 inches of terminal growth Do not increase N rates for trees 10 years or older.
  2. To plums, apply one-third (0.3) pound of actual N per tree for non-bearing trees and one (1.0) pound N for bearing trees.
