North Star Sour Cherry Tree

Here's a recipe that gets rave reviews for me. Cherry Pie Ingredients: 4 cups pitted, fresh or frozen sour cherries (I prefer Balaton), 3/4 cup sugar, 4 Tbs cornstarch, your favorite double pie crust, 1 1/2 Tbs butter, to dot, 1 Tbs sugar, to sprinkle. Heat cherries in pan on stove until most of the juice is released. Combine 3/4 c sugar and cornstarch in a small bowl. Pour into cherries in pan, stir and cook over low heat until thickened. If filling is too thick add water, too thin add more cornstarch, or too tart add more sugar, stirring to combine. Remove from heat and cool. When cooled, pour into bottom crust, dot with butter and cover with top crust. Brush top crust with water and sprinkle with sugar. Pierce crust so steam can escape. Bake at 375F for about 50 min or till done. This recipe also works well as a cobbler or crumble.

Supreme! I would recommend buying supreme whenever it’s available. My trees have a thicker trunk and are taller.

Yes, prune now! Late-summer pruning reduces the tree’s energy for fruit production as well as its growth, so this should be minimal, using only thinning cuts. Thinning cuts remove an entire shoot, branch or limb up to the point of its origin and do an excellent job of opening up the canopy.

You need not worry about planting next to each other, they will not cross-pollinate.

North Star is a tart cherry, which means it's self-pollinating and doesn't need another tree to produce fruit; however, if you plant a different tart cherry nearby, you'll have larger/more fruit on both trees. The varieties must be different. The same variety cannot pollinate itself, and sweet cherry trees cannot pollinate tart cherry trees (or vice-versa), despite what you may read on the Internet.

This depends on where you live. In Minnesota where we have live our
summers can be hot and humid. Temps in the 90's and at times dew points
in the upper 60s to low 70s and these trees do well here. Average number of days
like described above in Minnesota a year are 12 to 15.The remainder of the summer temps in the 80s and due point, mid to upper 50s.

I don't think so unless you have a very big patio. I have a mature tree (in zone 5) that is now about 10 feet tall and at least 6 feet wide. Fabulous tree and I love it but is probably a little big for a patio and certainly too big for a pot.

When shipped, regular trees are about 3-4' tall and/or with a 3/8" or larger trunk diameter. A Stark® Supreme Tree is one of the season's top-grade, bare-root trees that gives you a head start on growing. When Supreme trees are shipped, they are about 4-5' tall and/or with a 5/8" or larger trunk diameter.

The blossoms are white. The fruit is excellent.
