Now is an ideal time to tidy up your hedges - there will be no nesting birds to disturb, and there will be limited regrowth so your hedges will look trim and tidy through until spring.
Take care when cutting back coniferous hedges that you don’t cut back into bare stems as they will not re-grow. Also keep plants from shading out conifer hedges as that will create brown patches.
Always trim hedges with a narrower top and wider base, this is so that if we have heavy snow it will not sit on the top of the hedge and damage the plants, but will be more likely to slide off.
Also, cut back the whip growth on Wisteria to 5 or 6 leaves on each stem. This should ensure more flowers next year.
