It’s important to prune roses to keep them healthy and vigorous. Although it can sound daunting, with different ‘rules’ for different varieties, it’s worth remembering that roses are tough and will bounce back even if you cut them back quite hard. Here’s how to prune your roses like a pro...
Apart from ramblers and some shrub roses, the best time to prune is a frost-free day between November and March. You’ll need sharp, clean secateurs and, possibly, long-handled loppers. The aim is to create a pleasing overall shape, while improving the air circulation around the plant to help prevent disease.
For all types of rose, start by removing dead, damaged and diseased growth and any stems that are rubbing against another branch. Cut to a strong, outward-facing bud. Then, depending on the variety you have, here are some simple guidelines to follow:
Rambling roses: Vigorous ramblers flower once a year (around June) on the current season’s growth. Cut them back in summer after flowering, removing some of the old growth completely so the rose is gradually rejuvenated.
Climbing roses: This variety flowers all summer and into autumn. To prune, train in the main framework of stems and then cut back side shoots close to this framework. Failing to prune will result in a tangled web of branches and a reduced number of flowers.
Shrub roses: These flower on old wood so need only light pruning with some removal of old wood to rejuvenate the plant. Be careful not to spoil the shape. Those that flower once should be pruned after flowering in summer. Repeat flowering shrub roses are pruned in late winter by cutting back the previous year’s growth by up to a third.
Hybrid tea roses: Prune by shortening all the strong shoots to four or six buds from the base. Any weaker shoots should be cut back to four buds.
Floribunda roses: Cut the strongest shoots to around 25-30cm above ground. Lightly prune the rest.
Ground cover roses: These need only light pruning unless you want to restrict the size. In particular, cut back any upward-growing shoots. Congested plants can be rejuvenated by pruning to about 10cm from the base.
Patio roses: Remove any twiggy growth and cut back strong stems to around 15cm. Take out any stems that spoil the overall shape.
Regular pruning will help your roses to grow well and produce plenty of flowers. It will reduce the risk of disease by removing any weak or damaged stems, and encourage airflow for a healthier plant. There’s no need to worry about over-pruning either. Roses are quite forgiving and it’s almost impossible to kill one in this way!
