I have been looking into doing some cherry picking this season. Unfortunately the news I have gotten from local farms has not been good. I checked with Kapnick Orchards in Britton, MI and they said they will not be doing U-Pick cherries this season. I also heard from Wasem's Fruit Farm in Milan, MI and there is some doubt they will be having u-pick cherries this year. They said their crop is small this year, but they will make a final decision in a week (on June 28). The weather this spring was not too kind to a lot of Michigan fruit crops. We had a warm start to the spring, which causes the plants to begin flowering early. But then at the end of April and start of May we had some freezes that did damage to the cherry blossoms. So it may be difficult if you want to pick your own cherries this year in southeast Michigan. However, you can still pick up farm fresh cherries. I got some from both the Ann Arbor and Saline farmer's market last week.
On the southwest side of Michigan, there are u-pick cherries available at Fruit Acres Farms in Coloma, MI. They have both sweet (started on June 19) & sour varieties available (starting June 26) for u-pick. You can call them for updates at (269) 468-5076. You can also visit their website for more information.
