Roses – pre-pruning tips

June 17, 2012 Filed under Soul food

If you are fond of your roses, now is a good time to give them their first haircut before the serious prune in July. Cut back your standard and bush roses by half, getting rid of dead and thin branches and tidy your climbing roses too. Then spray with lime sulphur which will get rid of the remaining leaves and reduce the disease and pest problems for the coming summer. (Make sure you clear away all the prunings and be careful not to spray evergreen plants in the vicinity of your roses.)

The part above the new shoot dies.

This means that a bush left unpruned becomes a tangled mass of dead and live wood bearing flowers of poor quality on spindly stems. Read more
