I have standard roses. As the weather warms, and after feeding with commerically purchased rotted chicken manure they are growing very, very fast.
Is there a way I can get them to produce more flowers rather than growing long stems like the one that goes out of frame in the top right of the picture below?
If I trim the longer stems off to bring it back to shape will that stop it flowering?
The roses pictured has been there longer than I've owned this house - so I guess it is at least eight years old. I pruned the head of all the roses at the end of winter down to a few sticks.
