Hi- Yes I know that sour cherries are grown in other states and other countries. We grow a few trees of a white fleshed variety of sour cherries, that are very popular in Lithuania. Michigan is by far the largest grower of sour cherries, and the whole midwest is severely affected this year, including door county. I know Pennsylvania has a much smaller crop of tree fruit too, and I assume New York state does too. New York state grows a lot of apples and grapes.
Out West in California and Washington they grow a lot of sweet cherries, and I believe California is the largest grower of sweet cherries, but they don't grow nearly as many sour cherries.
M6y sister normally sells bags of frozen and pitted sour cherries at her fruit stand, but she can's find them this year.
For the person that said that she found sweet cherries for sale for $1.99 a pound, and peaches on sale for under $1, yes, you can find them cheap, but they are shipped in. The cherries are either from California or Washington or Oregon, and the peaches are either from California or Georgia or South Carolina. Western cherries are OK, but the Michigan cherries I bought Saturday for $6 for one pint, are wonderful. I would rather have a small amount of wonderful cherries, as opposed to an unlimited supply of just OK cherries.
Don't even get me started on shipped in peaches in the grocery store. The last time I bought peaches at a grocery store, was about three years ago, when I bought some of Eckert's peaches at Whole Foods. They weren't bad., but they still weren't as good as most of the peaches my sister grows. Eckert's has a large peach farm in the St. Louis area. I will not buy peaches from Dominick's or Jewel, because they will only buy green peaches, which taste like cardboard. They won't buy local peaches or cherries for that matter anyway. They do carry some Michigan blueberries. The chain stores only want peaches that will keep for a week or more, and they only want to deal with mega farmer's. Meijer's does carry some Michigan peaches though. Hope this helps, Nancy
