Overseeding makes grass thicker and helps stop weeds.

The best time to overseed in the UK is in spring, especially April.

In April, it's not too hot or cold, and it rains, which helps seeds grow.

To overseed, cut the lawn short, then remove dead grass and debris.

Next, make holes in the lawn to help water and air get in.

Keep the lawn wet, and water it if it doesn't rain.

Stop birds from eating the seeds, and don't walk on the lawn too much.

When mowing, make the cut higher at first, then lower it later.
