Planted a cherry pit from cherry's in store of 7 only one is growing

I would consider that a success! Nurture it till large enough to be in a pot outside, then keep repotting until large enough to be planted in ground. See if this link helps. Congratulations! 🍒

Hello Anette, I read recently about growing a tree from a cherry pit. There is a lot to consider and a lot of prep work to actually have success. Consider yourself lucky. You are the very first person that I have heard of with a successful outcome. So, congratulations. All the best to you.

I agree with Naomie. 1 in 7 from store bought cherries is amazing.

if you have one growing, they must have been organic.

Grocery stores nuke all produce and therefore; the seeds can not germinate. Now if you could get some fruit off the trees, those would probably work. Good luck!
