Patchy lawns affect an estimated 80% of UK gardens at some point, with the most common causes being dog urine, heavy foot traffic, shade, drought stress, and chafer grub damage. Spring (mid-March to May) and early autumn (September to mid-October) are the two optimal repair windows, when soil temperatures sit between 8C and 15C. Overseeding with a quality ryegrass mix fills thin areas within 14-21 days.
Key takeaways
- Dog urine, heavy wear, shade, and drought are the four most common causes of lawn patches in UK gardens
- Spring (mid-March to May) and autumn (September to October) are the best times to repair, when soil is warm and moist
- Overseeding with perennial ryegrass germinates in 7-14 days and fills thin patches within 3 weeks
- Turf patches give an instant fix for bare areas larger than 30cm across
- Mowing below 3cm and removing more than one-third of blade height are the most common causes of self-inflicted lawn damage
- Watering new seed twice daily for 14 days is essential, missing even two days can halve germination rates
