Is it a good thing to raise the cutting height of the lawnmower in latter part of the growing season?

Question

Seems like when there is less rain, if the grass is cut too short, it has a tendency to shrivel up and turn brown late in the season.

Answer 1

keeping grass at 2 inches prevents a lot of dead grass. Grass has 2 parts--the roots and the leaves. cutting grass 2 short weakens it.

Answer 2

I would think you have a very good idea.........1 leaf protects another.......just like trees........kind of a build in cooling system......instead of a crew cut and all sunburned:)

Answer 3

Actually, It is recommended that you raise the cutting height of the lawnmower after late spring. Summer weather is hard on lawns and depending on where you live, chances are your lawn is probably quite brown and crunchy. About the first part of June I raise the height by one notch, and then another notch again around the first part of july. Having the clippings lay on the lawn helps shade the roots of the grass and provides nutrients for the lawn. I've noticed that since I have started doing this, my lawn is much greener than everyone else's on the block, and I have to water it less.

Answer 4

very normal for lawns to go dormant during dry spells-cutting it at a higher setting helps moister loss- protects the roots

Answer 5

LOL, that is what intelligent people who want nice lawns would do!  Not us!  I look forward to August. Lower them thar blades and let the sun have at that thar  grass!  Voila!  No more mowing AND saves gas!*

Answer 6

Most people cut too low.  In spring and fall you can cut a bit lower, but in summer's heat you should be cutting higher! Longer grass means longer roots and a more drought tolerant, heat tolerant lawn.  

suggestions:

In Spring and Fall mow bluegrass, ryegrass and fine fescues to 2- 2.5 inches.  In summer mow to 3 inches

Tall Fescue mow to 2.0 - 3 inches spring/fall and 3+ in summer
