The climbing rose is one of the most popular flowers in a garden. This species of rose has flexible stems that allow the plant to bend so that it can be trained to grow in any direction. Typically, the climbing rose will grow as high as 20 feet tall with the larger plants getting as large as 30 feet tall. This plant mimics a vine but must be trained to grow around supports. It will not attach itself on its own.
Choose a trellis for your garden that will accommodate the climbing rose plants. The trellis should be of high quality so that it will not need replacing often. It should also be structurally sound to withstand the weight of the growing rose bush.
Dig a hole for your rose bush that is twice the size of the container that it is in. If the pot is 4 inches wide, you will dig a hole that is 8 inches. The depth of the hole should be at least 2 feet deep and should be centered at least 18 inches from the support of the trellis.
Separate the root ball of the climbing rose before you place it into the ground. Do this by gently tapping the roots or gently shaking the root system out before setting it into the ground.
Cover the roots of the rose bush loosely with the original soil or with an all-purpose potting soil. Do not pack the soil down.
Apply a layer of rich organic compost and a 20-20-20 fertilizer at the base of the plants. The roses need a lot of food in order to produce successful flowers. Water the plants heavily with at least an inch of water.
Top the soil with a 4 to 6 inch layer of mulch at the base of each rose bush. The mulch will help the roses maintain moisture and will help aid in fighting weeds in the rose beds.
Water the plants again with another inch of water. The soil needs to be soaked in order to reach the root beds.
Tie the plants to the trellis so they will begin growing in the direction that you wish them to grow. You will need to continue tying the plants as they grow, in order to maintain the shape that you desire.
Water your plants daily when the weather is above 90 degrees. Water your roses every other day for 80 degrees and every three days for 70-degree weather. Use at least an inch of water and fertilize them after every new 4 inches of growth with a 20-20-20 fertilizer.
