WHAT TO DO
* Cut back broom when it has finished flowering, shortening the shoots that have flowered to within a couple of cms of the old wood. Do not cut into this older wood.
* Watch for suckers on roses. They always spring from the base of the shrub and the foliage usually looks different to that of the parent. The sucker's leaves look more like a wild dog rose's. Pull the suckers out if you can, or trace them back underground to their junction with the rootstock and cut them off there.
