Place your cherry trees in an area that gets at least six hours of direct sunlight per day to bloom and fruit. The area should be protected from prevailing winds but also should not be close to a brick wall or other heat sink. This may allow the tree to warm too quickly in the early spring, making it vulnerable to late spring frosts.
Inspect the trees in the growing season for insect pests. In Colorado, cherry slugs and peach tree borers are common pests that can damage the tree. Insecticides can be used to control pests or contact your local extension agent for organic solutions.
Water cherry trees deeply once per month after the chance of frost has passed. Discontinue the watering around the time of first frost in the fall to allow the cherry tree to begin its dormancy period.
Protect the trunk of the cherry tree from deer and other pests by wrapping it with trunk protector made from polyethylene or cardboard. Wrap the trunk from its base up to the first branches.
Prop up heavy horizontal limbs once the tree is mature. Push a wooden support underneath the branch or tie it to the main trunk from above. This is especially important to take care of before heavy winter snows threaten tree limbs from the additional weight.
