Tree roses, also known as rose standards, have a central cane that typically measures between 32 and 36 inches tall with a profusion of foliage and blossoms concentrated at the top. Tree roses are created from a variety of different rose cultivars through grafting techniques. Tree roses can have blooms at the base of the tree as well as the top; they may be grown in containers or in your garden.
Plant tree roses during the late spring if you live in colder climates or during the late fall if you live in warmer climates. Stand the tree rose in a bucket of water to soak the roots for an hour before planting.
Select a sunny location in your yard or against your house, preferably away from windy conditions. Mix organic compost in with your garden soil and prepare a hole twice as wide as the root ball and deep enough for the top of the root ball to be at soil level. After planting, water thoroughly and cover around the tree with a 3-inch layer of organic mulch.
Make sure that your tree rose receives at least 1 inch of water each week while it is becoming established. Water the tree rose more frequently during drought conditions.
Stake the tree rose with a wooden stake next to the center cane. Tie the cane to the stake with elastic ties. Your tree rose cane must be staked to bear the weight of the top-heavy blossoms and to protect it from wind damage.
Fertilize your tree rose with rose fertilizer once in the spring before the blooming begins and again in early summer when the spring blossoms have faded.
Protect your tree rose over the winter by moving it to a protected environment, or by mulching all the way up the center cane. To properly mulch a tree rose for winter, surround the cane with a cage of chicken wire and fill it with organic mulch.
Prune your tree roses according to the variety of roses growing at the top, but never prune the center cane. The optimum pruning time for tree roses is in the spring, after all threat of frost has passed. You should also plan to remove the dead canes in the winter to help protect against potential wind damage.
