when does grass stop growing uk

In the UK, grass typically stops growing when soil temperatures drop below about 5 to 6 degrees Celsius. This usually happens in late October to early November. As temperatures decline in autumn and soil cools, grass growth slows gradually until it nearly stops as winter arrives, commonly around late November to early December. During this dormant winter phase, grass remains alive but conserves energy in its roots, showing little to no growth above ground. The timing can vary somewhat based on local climate, elevation, and weather patterns each year. Regular mowing can continue until growth ceases, but once soil temperatures are consistently below 5°C, the lawn effectively enters winter dormancy and mowing can stop until spring when growth resumes. This pattern aligns with the cool-season grass types common in the UK, which flourish in mild temperatures but slow down in colder months.
