Rake your lawn to get rid of dead growth, stray leaves, twigs, and winter debris to let light and air to the soil level, encouraging the grass to grow. Re-seed bare or damaged patches of lawn, scratching up the soil with a rake first, before mixing a shovel of soil with a couple scoops of grass seed, spreading it in the patch you’re fixing. Rake level and keep well-watered until seeds germinate and the new grass establishes.
