The tree rose, also called the rose standard, is obtained by grafting a hybrid rose bush on a 32 or 36 inch stem and root base. Miniature rose bushes are also grafted onto short 24 inch stems to create a patio rose plant. Not cold hardy because there is no way to truly protect the grafted bud of the plant the tree rose often needs to be lifted in the winter and laid into the grown or simply moved into a garage for protection. The tree rose offers ease of planting and summertime maintenance.
Plant the tree rose in a location that offers at least 6 hours of sunlight per day. Choose a location that offers wind protection since the tree rose is susceptible to breaking in high winds.
Mix ample organic material such as peat moss, aged manure or leaf debris into the soil prior to planting the tree rose. The soil should feel crumbly to the touch.
Dig a hole that is twice the size of the tree roses root system. Gently place the tree rose into the hole. A bare-root tree rose will require you to spread its roots gently out into the soil prior to planting. Tamp the soil tightly around the tree roses root system to make sure that all air pockets are removed.
Apply 3 to 4 inches of mulch around the tree roses base to keep the soil moist and help keep weeds away. Use peat moss or bark chips.
Water the tree rose thoroughly. The rose bush appreciates moist soil but it will not tolerate a water-logged root system. Apply at least 1 inch of water per week.
Place a metal stake that is enclosed in plastic beside the trunk of the tree rose. The plant stakes are sold at most garden supply stores. Tie the trunk of the tree rose to the stake using cotton rope. Check the ropes often to make sure they are not cutting into the rose bushes stem.
Fertilize monthly in the spring and summer using a general purpose 12-6-6 fertilizer. Water the fertilizer into the soil. Use 2 pounds per 100 square feet of garden space.
