Thanks to their vigorous growth, most climbers and wall shrubs need to be planted with care in positions where they will be able to extend themselves comfortably. You may have to supply the plants with an appropriate support, depending on their own climbing method.
Climbers are no different from trees in terms of the space demanded for the roots, but most need some help in the period after planting to encourage them to grow in the right direction, up the supports you have provided. Since climbers will be planted close to a support such as a wall, where the soil may well be dry and lacking in nutrients, more preparation than normal will probably be necessary in order to give the plants a good start and help them to establish.
Walls, pergolas, fences, trees, and old tree stumps will all provide a useful backdrop or support for a range of climbing plants. You can also grow climbers over shrubs, or over another climber, but in the latter case you need to take care that the more vigorous plant does not smother the weaker one.
Some climbers are exceptionally vigorous, and unless the support is strong the combined weight of foliage and flowers may break it. Included among these hefty giants are the large rambling roses, like ‘Bobbie James’ or ‘Rambling Rector’, which will easily reach 33 ft. and need a large tree over which to roam. Clematis, with delicate stems and beautiful flowers, can be grown over shrubs, giving you Mowers for a longer period than just those of the shrub. The suitable clematis has a short but exquisite flowering period. The small-flowered Macrope Uila and Texensis clematis are ideal for this setting, but the anemone clematis is probably too vigorous and need support.
