Our apricot tree had many blossoms and without frost developed many apricots. They are not maturing and very few leaves are on the tree. What is the problem?

Without more detail, its difficult to say, but here are some possibilities for you to consider:

Apricot trees usually take 3 or 4 years to bear fruit to maturity. How old is your tree?

Although most varieties are self-fertile, others need a second variety of apricot for effective cross pollination. Fruit set is better when planted with one or two other varieties nearby.

Pollination may have been ineffective.

Sometimes trees get into an alternate bearing cycle where they produce a large crop one year, take the next year off, then produce a large crop the next year.

The lack of leaves suggests ineffective watering and fertilization may be stressing the tree. Drought stress would also impact fruit?s ability to ?size up.? Did you fertilize in spring? (The midst of summer is not a good time to fertilize as it may burn roots. Wait to late summer if you did not feed in spring.) Apply water around the entire tree?s dripline (canopy edge) where feeder roots are absorbing it. Be sure that water soaks through the root zone, about 3 feet deep for mature trees. A soil probe (any long pointed piece of metal) will help you determine how far water has soaked. It moves easily through wet soil but stops when it hits hard soil. I hope this info helps.
