Peach Tree over 7-8 years old and no flowers so far.

Question

In Ottawa we purchased a 2-3 year old peach plant & planted in our yard. Initially it grew very well. But during 2nd year’s severe winter & snow it died completely. However from the roots few branches (about 10) appeared. In the last 2/3 years 3 branches which grew over 6 feet have dried & the balance have grown to over 12 feet high in last 4-5 years, and the diameter at ground level for each branch is almost approaching to 3″. The plant is full with leaves & is spread over about 15 feet & most of the day it gets sun. It is now 5 years that we planted it. Why there are no flowers so far? What should we do? Earlier the same information I passed to Montreal Botanical as well a research US organisation dealing with peaches but did not get any response.

Answer 1

The bad news is that if your peach tree was grafted, your tree that grew from the roots probably was the rootstock your peach tree was grafted onto and not a suitable cultivar itself.

Here's an article that explains these terms and concept of grafting:

You can start over with a new tree, or consider using grafting technique to acquire and graft a selected desirable "scion" on to your existing tree.
