Roses should be regularly pruned so that they retain their vigor, stay under control and produce more flowers.
Cuts should be made 6mm ¼" above and sloping away at a 45º angle from an outward facing bud. Always use a good shape pair of secateurs, cheaper models will crush and bruise the stems.
For newly planted roses that are being trained up a pillar or post, wind stems round and round until you reach the pergola. Cut back the side shoots to 1 or 2 buds from the main canes. Tie any new growth down horizontally, if bare at base: Cut one of the main canes hard back to encourage new growth.
Cut out canes, which have flowered last year, and horizontally train new canes. If the rose is a number of years old, cut back side shoots on the old canes or back to where a new shoot has sprouted.
Hybrid Tea Bush
Prune out weak or diseased canes. Thin out and remove crossing canes. Cut remaining canes to about 20-25cm or 8"-10" to nearest bud. Vigorous varieties benefit from less hard pruning, around 45-60cm or 18-24"
Follow the same steps as with the Hybrid Tea except the main canes will be 30-35cm or 12-14". Any side shoots cut back by about two thirds or three shoots.
Shrub or New English
Shorten the main canes to a manageable height and side shoots to around two thirds or three to five buds.
After pruning any rose feed with a well balance rose food such as Toprose.
