Miniature roses need minimal pruning other than maintenance pruning.
Flowers are produced mainly on the current season’s growth, so our aim is to get a rose with healthy well-balanced new growth.
February – March. Cut out any weak and diseased wood.
Cut back strong stems to about 10 to 15 cm.
Any very vigorous shoots growing from the base can be removed completely.
June and July, dead-head to encourage flower production.
Renewal / rejuvenation pruning.
February – March. Cut back 1/3 of old shoots almost to the base.
Repeat for rest of old shoots over next 2 or 3 years.
This method of removing old wood and encouraging new growth should gradually rejuvenate your rose and replace old unproductive wood with new healthy growth.
