Japanese cherry trees in zone 4?

My girlfriend really wants a Japanese cherry tree which is listed best for zones 5-9, but we live in zone 4. Anyone know what kinds of problems we might run into with this?

Answers:
Gardening is a trial and error hobby. I have many plants in my yard that is zoned for a warmer climate. Japanese cherries are a beautiful tree and is worth the try, but they are prone to many insect problems. The most popular on the market is "Kwanzan". It is a double flowering type and does very well here in Cincinnati. I would suggest placing the tree somewhere in the landscape where it can be protected from the drying effects of the brutal winter winds. Another thing you can do is to water the tree during the winter months. This will help the tree by insulating the roots and will help the plant from dissecation.

Cherry trees need to go dormant during the winter, but cannot withstand extremely cold temps.

Unless im mistaken (possible) zone 4 is a colder zone, as in farther north.

So it really depends on how close you are to Zone 5. If close to the borderline, you would probably be alright.

Exact opposite if zone 4 is a southern zone.

Another possibility id to semi bonsai one.

Plant it in a large pot that you can move. Then in the winterif it is too cold, you put it in a garage or porch that is warmer than the outside, but not really heated.
