1. The Weather
|Drought is the main cause of a patchy lawn|
Solution: Always read and follow the manufacturers application instructions. Use a calibrated spreader (either a push along model or a powered spreader fitted to your lawn tractor) to accurately spread the fertilizer granuals on your lawn. If rain does not fall within two or three days of application, consider watering the garden.
3. Dollar Spot
|Example of 'Dollar Spot' disease|
Solution: Annual feeding of the lawn with a nitrogen-rich fertilizer can help prevent the disease from taking hold. This should be done each spring - ensure that you read the manufacturers instructions when applying the fertilizer. Scarification and aeration of your lawn in autumn will ensure that your lawn is fighting fit. If Dollar Spot persists, consult with your local garden centre for a suitable fungicide treatment.
