Climbing roses grow well in East Texas because they thrive in the acidic soil and moist conditions. Old climbing rose bushes last for generations if pruned and fertilized correctly and can be seen rambling around old fences and homesteads while driving through the country. Climbing roses don't actually climb over their support structures such as trellises like a vine, but must be tied or attached to the structure. Pruning for control or for shape is done after each bloom period, usually in late spring. If you prune before a bloom period, for example in the winter, you will cut off blooms intended for the spring bloom period.
Plant climbing roses next to a support, such as a fence or trellis, in a location that receives at least six hours of full sun each day, using a shovel to dig a hole wide enough to accommodate the roots and deep enough so the plant is as deep as it was in the nursery pot or previous location. Plant the climbing rose where it will get good air circulation to prevent mildew and fungal diseases from attacking the leaves. Roses prefer a well-drained location that stays moist but not wet.
Add planting mix around the base of a new climbing rose plant that is one-half compost and one-half native soil. Add water to soil when planting to prevent air pockets from forming around the roots of the new climbing rose plant.
Add a rose fertilizer around the base of the plant and add continued applications of rose fertilizer in the amount and on the schedule instructed on the fertilizer container label.
Mulch area over the roots of the climbing rose plant by adding a one-inch layer of mulch. Leave a one-inch gap between the trunk of the climbing rose and the mulch to prevent fungal diseases from spreading to the plant from the rotting mulch. Keep a layer of mulch over the plant's root base to prevent wide fluctuations in moisture levels.
Prune the climbing rose bush so that you will eventually have five to seven canes to work with and continue to remove all other canes that sprout from the ground so the plant's energy will be directed to the five to seven canes left to grow producing bigger blooms. Prune out all dead wood to keep climbing rose looking fresh and to remove potential disease problems. As the climbing rose grows attach to structure such as a trellis with plastic garden tape or another material that cannot cut through the branches when the wind blows against the plant.
