PRUNING

Prune new roses according to the advice on the despatch note. In subsequent years, either learn to prune by studying a brief and practical explanation such as in 'The Rose Expert', or apply a few very simple guidelines as follows:

General

Use sharp secateurs that cut scissor style, not anvil style. (Anvil crushes, scissor slices).

Prune in late winter, ideally in the second part of February.

Do not be afraid to cut off branches that have already produced early shoots.

Remember, the reason for pruning is to regenerate growth and to keep plants in shape.


To Prune Bush Roses - including Floribunda, Hybrid Tea and Patio

Cut out completely any branches that are dead, dying, damaged, or diseased;

Cut out any weak, spindly, twiggy and non-productive growth;

Cut out any branches that crowd the centre of the bush, aiming for the inverted 'umbrella' look;

Shorten all remaining branches by cutting off two thirds of last seasons' growth.


To Prune Garden Shrub Roses
Repeat flowering Varieties

Either, do not prune them at all if their natural form is wanted; or, prune them periodically (say, every 3 years) by following the procedure as for bush roses, but shortening the previous growth only by one third.

To Prune Old Fashioned Garden Shrub Roses
Once flowering Varieties

Old-fashioned Shrub roses that do not repeat flower should be pruned immediately after flowering, or not at all. If not pruned annually they benefit from occasional thinning of old wood in winter.

To Prune Landscape Shrubs & Ground Cover

Pruning is optional. Landscape shrubs will tolerate neglect and may be left unpruned unless they outgrow their position, in which case they may be cut
back according to necessity. If pruning, the same principles apply as for Garden shrubs.
