Overseed Lawn: How to Fix Thin Grass and Grow a Thicker Lawn in the UK
When your lawn looks more like a patchwork quilt than a smooth green carpet, overseeding, the process of spreading new grass seed over existing turf to fill in bare spots and boost density. Also known as lawn renovation, it’s one of the most effective ways to bring life back to tired grass without tearing it all up. You don’t need to start from scratch—just add fresh seed, improve soil contact, and give it a little care. It’s not magic, but it works if you skip the common mistakes most people make.

If your soil is hard, compacted, or covered in thatch, the seed won’t reach the dirt. That’s why lawn repair, a set of practices to restore damaged or thin turf. Also known as lawn rejuvenation, it often includes aeration and raking before overseeding matters more than just buying a bag of seed. The best results come from combining overseeding with proper soil prep. Think of it like planting a garden—you wouldn’t just dump seeds on concrete, right? Same rule applies to grass.
