Hedges are fast-growing and need to be regularly trimmed. Choosing the right hedge trimmer will depend on the size and density of hedge and the distance from a power source. There are three types of powered trimmer:
Corded hedge trimmer
Run off mains electric and are fairly light and easy to use, but you must keep the cable away from the blade.
Cordless hedge trimmer
Run off a re-chargeable battery, cordless hedge trimmers are lightweight and quiet. Best suited to smaller or lighter hedges.
Petrol hedge trimmer
Petrol hedge trimmers are ideal if you have large dense hedges far from a power source. They are larger and heavier than corded or cordless, but more powerful.
The longer the blade on the hedge trimmer, the more you cut with each sweep. For most gardeners, a blade between 40-60cm is suitable.
The wider the gap between the teeth on the blades, the larger the branches it can cut and the more quickly the hedge trimmer will cut small branches.
