UK grass and lawn weather
When should you cut the grass?
Cut the grass when it is growing, dry enough to mow cleanly and the weather gives you a safe cutting window.
Short answer
The right time depends on season, growth rate and local weather. In spring and summer you may cut more often; in winter you may not need to cut at all.
