The answer to 'why is my seeding' is that there are several common causes for poor seed germination or establishment, including improper soil preparation, incorrect seeding depth, competition from weeds, and environmental factors like drought or excessive moisture. The symptoms may include patchy, thin, or uneven grass growth.
To troubleshoot, first check that you properly prepared the soil by loosening and leveling it, adding any necessary amendments like compost, and removing weeds. Ensure you planted the seed at the recommended depth - typically 1/4 to 1/2 inch deep. Monitor soil moisture and provide supplemental watering if needed, especially during hot, dry periods. If weeds are outcompeting the new grass, you may need to hand-pull them or apply a selective herbicide. If the issue persists, it's best to consult a professional landscaper who can assess the specific conditions of your lawn and recommend the best solution.
