Prune Texas sage by preparing your pruning shears, cutting the branches to different lengths, clipping off the tips of stems and occasionally hard pruning to stimulate growth. You need a pair of pruning shears, water, a soaking container and rubbing alcohol.
- Sterilize the pruning shears
Before pruning Texas sage, sterilize the pruning shears to avoid transmitting diseases to the shrub. Mix 1 part water and 1 part rubbing alcohol in a container. Place the shears in the container, and allow them to soak for five minutes. Remove them from the solution, and rinse them. Allow them to air dry.
- Cut the branches to different lengths
Control the size of the bush by cutting the branches to different lengths. Trim the branches just above the nearest bud.
- Clip the tips
Shape the bush by shearing or clipping of the tips of the stems. Do not shear the shrub too often, as it can cause the plant to become woody and produce less flowers.
- Hard prune the bush
Every three or five years, hard prune the limbs to encourage growth and rejuvenate the bush. Cut back a third of the oldest branches to within 6 inches of the ground. Prune the other branches as desired.
