Rose trees, known as standards, are created by grafting a hybrid tea rose onto a central cane, usually 32 to 36 inches tall. These beautiful trees create a spectacular showcase plant in your yard, but require some extra attention. Rose trees are easily toppled by high winds and require staking. They also sustain more damage from harsh sun and freezing winter temperatures and may need extra protection. Maintain your rose tree's shape with frequent pruning.
Plant your rose tree in a garden location that receives at least six hours of direct sunlight per day. An eastern location is preferable to provide lots of morning sun. Plant your rose tree in early to late spring. Rose trees need good drainage and plenty of air circulation. Plant your rose trees at least 3 feet apart and away from any other shrubs or trees.
Dig a hole 15 to 18 inches deep and wide with your shovel. Set the soil from the hole in a pile on the ground. Mix 3 oz. of superphosphate fertilizer and three shovelfuls of compost with the soil.
Remove your rose tree carefully from its pot and place it in the hole. The plant should sit at ground level. If the hole is too deep, remove the rose tree and add some soil to the hole. Backfill the hole with your amended soil, pressing down gently to remove any air pockets.
Water your rose tree deeply with a slow trickling hose for 40 minutes. Thereafter, water your rose tree once a week to a depth of 12 inches. Adjust your watering schedule for very dry or very wet weather.
Apply a 2- to 3-inch layer of wood chip mulch to the soil around the tree to protect your rose tree from moisture loss.
