Growing Roses In Containers
I have grown Hybrid Tea and Floribunda rose bushes in containers, as well as miniature and mini-flora rose bushes. The containers I have used for container roses are approximately 20 inches (50 cm.) across at the top and 14 to 20 inches (35-50 cm.) deep. It must have a drainage hole, or your roses run the risk of problems such as root rot, mold and fungal attacks. I add a thin layer of ¾-inch (2 cm.) gravel in the bottom of the pots to create a drainage plain area. The soil used in the container must be a good draining potting soil. If the container rose is going to be left outside or in an exterior environment exclusively, an outdoor potting soil mix is fine to use. If you plan on moving the container rose bush inside for the winter, do not use an outdoor potting soil mix, as the aroma it may generate might not be something you want in the house! Do not use clear containers for growing roses in pots, as they can allow sunburn of the root system. Large container roses should be placed in drainage pans that are set upon either wooden or metal coasters with wheels on them. The coasters make it easy to move the container rose bushes around to get the optimum sunlight. They also make for easy tending, as well as moving into the garage or other protected area for the winter. Do not let water stand in the drain pan at the bottom of the pot for longer than an hour, as this will defeat the purpose of the drainage holes and lead to the same root problems as in containers without drainage holes. Roses planted in containers will need more water than roses planted in the ground. During the summer your rose containers will need to be watered daily. On days where the temperatures exceed 85-90 F. (29-32 C.), water twice a day. You can also use a water soluble fertilizer and add this to the rose’s water once every two weeks. Roses are heavy feeders and need frequent fertilizing.
Types of Container Roses
Here is a list of some of the rose bushes I have had success with in various containers:
Daddy’s Little Girl Rose (Rich Pink Miniature) Dr. KC Chan Rose (Yellow Miniature) Lavaglut Rose (Deep Red Floribunda) Sexy Rexy Rose (Pink Floribunda) Honey Bouquet Rose (Yellow Floribunda) Opening Night Rose (Red Hybrid Tea).
This is just a short list of roses suitable for container roses; there are many others as well.
