I tried searching on here and couldn’t find anything, but we have a Utah giant cherry tree that has some larger cherries that are still green and a whole lot of little tiny cherries that are turning red. Does anyone know what is going on here?
The tiny red ones were likely unpollinated and will fall off. Did you have good pollinators and bee activity?
Thank you for your reply.
I have been very busy, but did not notice a lot of pollinator activity, might have been bad timing with weather and rain.
Meanwhile, our little English Morello is covered in cherries and Montorency has a lot too!
Bing only has a few.
I don’t know why the smaller pie cherries have so many more cherries than the sweet cherries.
They always set well. I think they may be self fertile. Utah Giant and Bing definitely need pollination. It should improve as the trees get bigger.
I’ve got Utah Giant and no pollinator variety. I’ll need to get something going this winter. I do have a self fertile low chill sweet cherry but that won’t help.
English Morello and Montmorency are sour cherries and self fertile.
Most sweet cherries like Bing and Utah Giant need cross pollination partners. Sweet and sour cherries are two different cultivars. They don’t cross pollinate each other.
There are several cross pollination tables of sweet cherries on the Internet like this one.
Those little sour cherries are rock stars, not very big at all and covered in cherries.
We’ve tried unsweetened Montmorency cherry juice and dried cherries and both are delicious. Never had a fresh one. I hope we get to try a fresh one this year. I know there are green cherries on the tree now, but I’ve learned not to count them until they’re in my mouth. 
Why won’t the self fertile sweet cherry help the Utah giant? Do they bloom at different times?
I just saw that Black Tartarian also has a cherry on it.
All of our trees are relatively young so I imagine things will improve in time.
Black Pearl and Rainier have not blossomed yet for us.
Craig Crimson died from the graft up and will be replaced by the local nursery, but with a different tree because they don’t have that one in stock. That’s why I was trying to pick between Indian free peach, candy heart, pluerry and Hollywood plum And all are on citation. I don’t know how I feel about citation.
I had read that early fruit ripened fruit could be from bug damage so I was worried that all those little tiny red cherries were caused by bugs.
I am glad to know it just might be not enough pollination.
The self-fertile, low chill cherry will bloom before Utah Giant.
Thanks, yes I understand, but I think the sour cherries being covered with cherries shows that maybe we had enough pollinators? They are self fertile but not parthenocarpic right? That’s a question, not sarcasm.
In sweet cherries, we have Utah Giant, black Tartarian, Bing, Rainier & Black Pearl.
I think they are a good group for cross pollination but not all of them are flowering yet.
I do feel like I haven’t seen as many bees as last year… I hope the population isn’t declining.
I intend to have honeybees some day but not till I get everything else in order so it might be a while.
