Minute Meltdown: Heatwave Survival Guide Part 2: Mowing

Yesterday I told you how to water properly.

Today's hack will make or break your lawn for the rest of the year: mowing height

Grass is solar powered. The more leaf on show, the more energy it can absorb from the sun, the more water stored, the healthier the plant, the deeper the roots. 

When over 25 degrees, grass enters a state of dormency. Which means it'll stop growing to conserve energy and sometimes turn a bit brown. 

If you cut your lawn short, not only will it absorb LESS energy from the sun, but it'll be too hot to grow itself out of trouble. 

It'll then stay short for days/weeks, without shade and bake in the sun. 

Whatever height you're cutting at, go up a notch. 

Long enough to shade the soil and hold moisture. Short enough to still look tidy.

The lawns that survive August are the ones cut at 40mm. Not 20mm.

As promised, lawn tips in under a minute.
