Mold on cherry fruit
 

We have a mature sweet cherry tree (Stella, sold as self-pollinating)
that has produced very well for quite a few years. This year we had a
warm and very wet spring. We're in zone 5/6, very near lake Erie
which moderates the weather. The tree set its usual abundant crop
but just as they started to turn, a mold started developing on the
fruits, and the whole crop shriveled up. My concern is what I should
to to protect the tree now that this has happened. The leaves seem
healthy, and I don't find an abnormal amount of insects. Since it is
a full sized tree, and my climbing days are over, I have not kept it
as pruned as I do my dwarf tree, so I think my fall project will be to
do a drastic pruning and try to get more breeze into the tree for next
year. Is there anything else I can do for it?

Sounds like brown rot. Do a web search, and you'll find sites telling you
how to deal with it (what and when to spray.) Good luck.

As far as the climbing thing, get yourself an extension pruner. You can cut
branches as high as 12-15 foot reach with one of those, and if it has a saw on
the end, you can do some pretty big branches.

Thanks for the information. The pictures at the web sites confirm
that it is brown rot.

As for climbing, this is a very large fruit tree, easily 25 or 30 feet
tall, so I'm going to try and remove all the residue of the infection
using a ladder.
