The apple tree is a traditional home fruit tree. It is so popular that songs and poems are written about apple blossoms. When an apple tree does not bloom, it may be due to tree age, variety, weather and other factors.
According to Richard Jauron, Iowa State University horticulturist, a backyard apple tree may not bloom until 4 to 6 years of age.
The kind of apple tree affects its blooming. Jauron reports as an example that the Jonathan variety will bloom and bear fruit sooner than Red Delicious.
Cold weather may freeze and kill flower buds and prevent blooming.
Heavy pruning promotes leaf growth and may cut off fruiting wood that produces blooms.
A healthy apple tree does not need much fertilizer. Excess nitrogen fertilizer promotes lush green growth and inhibits blooms.
The apple tree requires a sunny location. The tree needs six to eight hours of sunlight for healthy blooming.
