I'm looking to add a plum tree to my backyard in Plymouth. The ground has a lot of clay. I'm looking for a tree that produces large edible fruit and can survive our winters. I would appreciate suggestions on what kind and if I need two for pollination. Thank you.

I would suggest first of all that you do some amending to the planting site(s). Mix in a good amount of compost with your clay. This will help the water to drain and allow the roots a chance to develop. Don't just fill the hole but mix well. Secondly there are many plum trees for our zone. Only one, Mount Royal, is self-fruitful. It does not need a second tree. The others do require two. Here is a link to our publication on plums and other stone fruits with description of the tree size and fruit: http://www.extension.umn.edu/garden/yard-garden/fruit/stone-fruit-for-minnesota-gardens/#about
