The answer to 'seeding not growing' is that there are several common causes, including improper soil preparation, incorrect seed selection, inadequate watering, and competition from weeds. Symptoms may include patchy or thin growth, slow germination, and the presence of weeds or moss. Solutions can include testing and amending the soil, using the right seed for your climate and conditions, watering consistently, and controlling weeds.
If the seeding issue persists despite your efforts, it's best to consult a professional landscaper. They can assess the underlying causes and recommend the best course of action, which may involve re-seeding, soil remediation, or other measures to establish a healthy lawn.
