you can grow sweet cherries in zone 5...Traverse City..the cherry capitol ...grows sweet and sour cherries, peaches, pears, plums, and all sorts of stuff..but they have the national cherry festival here in July to celebrate the cherries that they produce..Michigan..
Honestly, i live a zone colder than you..part of my property is zone 4..and the higher areas i grow more tender zone 5 crops ..and i can grow a LOT of stuff.
you'll get used to the area ..if you moved recently..remember up north here we had the coldest winter in 60 years and the second coldest summer in 60 years..so this has been a fluke of really cold bad weather around here..give it a try next year..
i put in two beautiful sweet cherry
trees in the spring..and totally expect a crop next year..
read up on how to plant sweet cherries and other fruits..in zone 5..you generally
should plant them at the top of a slope so that frost will drain away..mine are on the north side of my houise and have a slig slipe that goes down to a colddamp spot in the ayrd..
in zone 5 you also should be planting windbreaks on the n and west of your property to help protect rops from wind exposure..
roldae nas some good
books out on palnting fruits and vegetables..and there are some books such as zone 5 gardening..a book written just for zone 5..the new northern garden is another book for cold weather
