I keep seeing sand cherry bushes advertised in several different catalogs. I like the idea that they are sweet and cheap and most importantly short (I can't climb ladders). Does anybody have any experience with them? How much will they produce? Do you need another type of cherry to cross pollinate? Is that a good pie cherry? Hubby likes cherry pie and I would love to make some pie filling. We also like banana splits and fruit cake, LOL! I'm also thinking that cherries would be good to dehydrate?
