I just picked these last week from my tree. Yummy!
This picture is from the web, also known as Rainier Cherries. These are not pie cherries, just good eatin' cherries. I think you can also make wine from them too.
I don't use any sort of pest control or fertilizer on my tree and I don't want to start, so hopefully there is no reason to be worried. I did send an inquiry to the Washington State Extension office just to be sure.
This concludes today's lesson... 
The next post will be all about Fred, I promise!
