How To Repair And Prevent A “Scalped” Lawn – 3 Simple Steps

How To Repair And Prevent A “Scalped” Lawn – 3 Simple Steps

You’ll know the lawn has been scalped if after mowing there are brown, sheared looking or scaled patches in your lawn.  Grass needs the green blade to soak up the sunlight in order to photosynthesise (turn sunlight into food) and grow.

When the lawn is scalped it means that the grass no longer has the ability to make its own food and may need help to repair itself.

So, you’ve been a little too happy and pulled the lawnmower out and gone straight at your lawn without checking the blades. Now your back yard looks like a kid who took the clippers to their own head. “Don’t worry its only grass/hair it’ll grow back.”  Well, maybe not on its own.

Here are a few ways to help it along. The grass, not the hair, that just needs some time.

Step 1 – Water the lawn deeply and gently

You will need to take into consideration the climate particularly the amount of rainfall you’re having. If there has been no rain you may need to water a few times a week. Don’t forget the best time to water is early morning or late evening. When the humidity is high and the temperature is low.

Step 2 – Add chelated iron 

Chelated iron encourages greening and growth. Make sure to follow the instructions of the manufacturer carefully.

Warning: Never fertilize a scalped lawn with a fertilizer containing Nitrogen!

Step 3 – Analyse the problem

Is the lawn looking uniformly scalped?  The setting on your lawnmower may be too low. Check into the correct grass length for your lawn and only mow to that height.

If however, there are only patches of the lawn looking particularly short you may have uneven ground to contend with.

To fix this problem add topsoil to your lawn 2.5 cm deep per time. Allow the turf to grow thick before adding more.

Seed may also need to be used in extreme cases. If your lawn is struggling to repair be sure to get the correct seed for your turf. Apply following manufacturers instructions.

Repairing Scalped Lawn - Mowing

Prevention is always better than cure so here is the best ways to ensure your lawn will remain un-scalped.

  • Mow the lawn at the recommended height for your grass type. Never remove more than one-third of the grass blade each time. If your lawn is overly long set your mower quite high and lower it each time you mow.
  • Sharpen your mower blades. The sharper your blades are the less you will need to mow. There is also less chance of scalping. The blades will cut cleanly instead of pulling at the grass taking more of the grass blade.
  • Mow in cooler temperatures. Avoiding mowing your lawn in the heat of the day will help your lawn recover faster if accidentally scalped. Less heat on the grass immediately after mowing will mean less dehydration. If you do cut it too short there will be quicker recovery time if it can retain moisture.
