The answer to 'my seeding looks bad' is that there could be several common causes, including poor soil preparation, incorrect seeding techniques, drought, or pest/disease issues. Symptoms may include patchy, thin, or uneven grass growth, weed invasion, or bare spots.
To troubleshoot, first inspect the soil to ensure it was properly tilled, amended with compost, and leveled before seeding. Check that you used the right seed type and spread it at the recommended rate and depth. Make sure the seeded area is receiving adequate water (1-inch per week) until the grass is established. Look for signs of pests, disease, or other problems that could be affecting the new grass.
