The term "patio rose" is not an official rose species but rather refers to any rose that stays small enough to be grown in a container on a patio. Minifloras, not to be confused with miniature roses, are considered patio roses. Minifloras are the hybrid result of crossing miniature roses with standard roses. They have larger blooms than miniatures on plants that stay small. Miniature roses are also considered patio roses.
A patio climbing rose will not grow to the size of a standard climbing rose but will still grow quite tall. They typically reach heights of 5 to 10 feet, but some can grow taller under the right conditions. A cooler growing climate and shorter season will result in a smaller plant. Good maintenance practices also influence the size and growth rate of patio climbing roses.
Climbing patio roses do not have to be grown as climbers. Rosa "Jeanne Lajoie" is a climbing mini with stems sturdy enough to grow without a support structure. Rosa "Red Cascade" is a climbing mini that will grow up to a height of 9 to 12 inches and then spread out along the ground. It can be trellised or grown as a groundcover. A trellis can be purchased at most gardening supply stores, but minis can be trained to climb up just about anything. A section of fence or lattice works well, but they can also be trained to climb up a 4-by-4-inch post. Simply wrap the canes around the post as they grow. Regardless of the type of support structure, the stems must be held to the structure with twine or ties. Climbing roses do not have tendrils to hold onto the structure by themselves.
Always deadhead roses as the blooms begin to fade. Patio climbers also need to have their stems pruned. Patio climbers that bloom once for several weeks in the summer produce flower buds on old wood or stems. They should be pruned immediately after they bloom. Pruning them in the fall or spring will remove the flower buds. Patio climbing roses that bloom off and on from spring until first frost are repeat bloomers. They can be pruned at any time, as they produce flower buds on both old and new growth. Remove dead stems from either type at any time throughout the year. Old canes should be removed at the base when new canes emerge. Trim side or lateral stems down but leave a length of stem with four to six new growth buds on it.
Patio climbing roses require at least six hours of direct sunlight each day. They grow best in soil with a loamy consistency that drains well. Water them deeply in the morning as often as necessary to keep the soil from drying out. They will require approximately 4 gallons of water per week when daytime temperatures are in the 80 degree F range and 6 gallons when they are in the 90 degree F range. This amount should be divided into several waterings per week to maintain consistent moisture levels. Give them fish emulsion or rose fertiliser every two to four weeks during the growing season a day after the plant is watered. Do not give fertiliser to thirsty roses. Apply 2 to 4 inches of mulch to help maintain moisture and control weed growth.
