Why are my northern hardy pears blooming but not producing any pears?
I have about 10 northern hardy pears - no blossoms and never any pears. What might be going on? Is there a fertilizer that might work?
Pear trees grafted to dwarfing rootstocks require 4 or more years to begin bearing fruit, while standard-sized trees may require 8 to 10 years. Late spring frost may damage developing buds, flowers, or fruit on frost-prone sites. Pear trees growing too vigorously are more susceptible to fire-blight infection than those making moderate growth.
Fertilize young pear trees with up to a pound of a general garden fertilizer such as 10-10-10 or its equivalent. Older pear trees (new growth each year) need no fertilizer.
