A few years ago, I had several fruit trees planted on my property. Different varieties of Apple, pear, and plum. Upstate NY, Hardiness Zone 5a.
Among other issues, I seem to be having big problems with my plum trees. There are two Burbank and one Santa Rosa.
The first year after planting, there were a few plums. After that, nothing. Last year, it seemed the Santa Rosa died. No leaves. Both Burbank trees had leaves but no fruit (likely because the other wasn't there to cross-pollinate?)
This year we replaced the dead Santa Rosa with a Methley plum and also added a new Santa Rosa plum.
Existing trees are about 8ft tall. New trees are about 4ft tall. The soil is not the best (quite a bit of red clay in the area) and everything seems to grow rather slowly (Although there are plenty of wild apple trees that fare very well).
While all my other trees are full of leaves and blossoms, the Methley plum and new Santa Rosa have no leaves. Also, only one of the existing Burbank plums has leaves. The other appears to be dead or dying. (We also planted a Northstar Cherry at the same time, which is full of leaves and blossoms).
Am I doing something wrong? Is this just a bad location for plums? Is there anything I can do to correct the situation and help these trees thrive?
Thanks in advance.
