There is nothing haphazard about the method of twining. The plants of each species invariably twine in one direction, start the winding of young vines around their support in the right direction. By knowing in advance how each vine climbs, the proper means of support can be provided for those selected.
Most vines will quickly revert to a tangled mass of foliage over the ground if they are not given the proper means of support or a reasonable amount of care and maintenance. The best type of support for vines is the one that gives the required structural strength and stability, and at the same time is neat in appearance.
Vines need pruning
to be their best
Pruning is necessary for the removal of old wood which helps keep the plant within bounds and produce better bloom. As with ornamental shrubs, flowering vines are pruned according to flower production; those that flower on new wood are pruned before new growth begins, those that flower on last season’s growth are pruned immediately after flowering. Since vines that are grown for foliage are pruned to control growth and direction, timing is less critical than for flowering vines. If vines are allowed to over grow, they may require several cuts to each stem so they can be untangled.
