 Grass trimmers are great for tidying up the edges of your lawn after mowing, and they're available in three different power types. Corded grass trimmers plug into the mains electric, so are ideal for trimming and edging smaller compact gardens. Cordless grass trimmers are better for larger gardens, allowing you to move further from the house or power source, and there are also petrol power trimmers, which are the best at tackling long grass, coarse weeds, or rougher vegetation. They're great if you have a wild garden to keep looking nice.
