Expert Tips for Best Results
Measure Accurately
For irregular shapes, break your lawn into squares or rectangles. Measure length x width for each section and add the totals together.
Soil Preparation
Good seed-to-soil contact is vital. Aerating your lawn before overseeding increases germination rates by up to 30%.
Watering Schedule
Keep the top inch of soil moist until seeds germinate. This usually means watering lightly 2-3 times a day.
