Con­trol climbers

Gardeners' World - - Autumn Pruning Guide -

Plants grown to cover fences, walls, trel­lis and per­go­las tend to be vig­or­ous and will have of­ten made a mass of growth by this time of year. Au­tumn is time to un­tan­gle way­ward stems and cut out the old­est stems to re­duce weight on the plant’s sup­port. Most climbers are trained into a frame­work of main stems to cover the sup­port, with the side shoots going on to pro­duce flow­ers. Ex­cess growth needs to be kept in check to stop it out­grow­ing its wel­come. Also cut out any weedy growth so that all the plant’s en­ergy in the fol­low­ing sea­son is directed into the strong­est shoots. Train­ing the main stems hor­i­zon­tally will re­sult in more even side growth from buds along its length. Do re­mem­ber that when you prune, there is a risk of cut­ting out wood that will flower next year, so avoid trimming climbers that flower be­fore July.

What to cut Hardy, de­cid­u­ous climbers and tough ev­er­greens.

Where to cut Re­move the tips of very vig­or­ous growth to keep climbers in bounds and cut one or two main stems if there are plenty of oth­ers to take their place.

When to cut When climbers have out­grown their space or could be blown down. Oth­er­wise, leave them un­til the rec­om­mended times for in­di­vid­ual va­ri­eties.
