Cut Away All Unproductive Material Beneath Foliage
Give climbers a drastic pruning if there is unproductive material beneath the foliage. Use a pair of hand shears for this job.

Climbers stand on other plants’ shoulders to reach the light, then hog as much of it as they can. As a result, they may grow up out of sight, leaving their trailing bare stems behind—not ideal in a small garden. An easy remedy is to cut them back severely, either in late winter, as for many late-summer- or fall-flowering clematis, or every few years, as for honeysuckle. Climbers that flower early in the year and bloom on stems made the previous year should be trimmed after flowering.

When to Prune Climbers

Different types of climbers require pruning at different times of year—often depending on when they flower and whether the flowers appear on new or old stems. Clematis fall into three main groups: those that flower in late winter or spring; those that flower in early summer; and the later-flowering types that bloom from midsummer to fall. For the best flowers, each should be pruned in a different way. Some woody climbers, including actinidia, parthenocissus, and wisteria, should be pruned in winter when dormant, like many trees and shrubs, although wisteria needs further pruning in summer for the best results.

Pruning and Training Wall Shrubs

Certain shrubs, while not actual climbers, can be treated almost as if they were by growing them against fences, walls, and trellises. Use the same pruning methods as for freestanding plants, but tie in stems during the summer in order to guide growth over the surface to be covered. At the same time, shorten any shoots that are growing away from the wall to make sure the shrub stays neat and narrow.

Pyracantha, cotoneaster, and ceanothus make excellent wall shrubs; all flower in spring at the base of stems made the previous year. Make sure that the wall is in good condition before fixing a trellis to it, as any repairs will be difficult once the plant is established. When pruning, take care not to cut back too hard into the old wood if you want blooms and berries. Shorten all new sideshoots in midsummer, leaving two to three leaves to encourage flower formation the following year, and to make any berries more visible. Pyracantha can be trained up a wall or a fence like a climber. New berries are formed at the base of stems made the previous year, so take care not to prune them off.

    I liked your climbing plants, which are pleasantly aromatic. These climbing plants provide an elegant way to define your property boundaries. Vibrant flowering vines provide decorative cover for arbors, trellises and fences and can give a cool ambiance to your yard.

Pruning and Shaping Hedges

Pruning and Shaping Hedges

When close-clipped and uniform, hedges create a sense of neat formality; when mixed and billowy, they are a garden in themselves. Whichever look you prefer, hedges will often need to be trimmed, fertilized and shaped to promote healthy growth and maintain your landscape.
