How to use

Miracle-Gro® Thick’R Lawn is to be used on thin lawns to create a thicker, greener lawn.

Lawn preparation: Cut the lawn short at lowest mowing height, rake out dead grass and debris and gently loosen the top soil.

Shake and apply: Shake well before use to mix the pack contents. Miracle-Gro® Thick’R Lawn is applied at 50g/m² and should be applied straight after the lawn preparation.

Application by hand

  1. It is recommended to wear gloves when applying by hand.
  2. The product can be applied by hand at 50g/m², and should be applied evenly.
  3. Using your hand, apply half of the product in one direction and the other half in the other direction (criss cross pattern) to get an even coverage. For a visual guide to the correct application rate, first spread 1 handful over a small measured area.

Application by spreader

It is recommended to apply Miracle-Gro® Thick’R Lawn by an Miracle-Gro® Spreader for an even distribution. Use our easy-to-use spreader settings table to set Miracle-Gro® spreaders correctly when using our products.

Any other advice?


Continue with mowing on a regular basis once the lawn reaches the desired mowing height. Regular mowing will help maintain a thick lawn.


If no rain falls within 48 hours, water the product after application. Then water twice a day or as needed during the first two weeks to keep the surface moist to support seed germination and establishment.


It is recommended to feed the lawn on a regular basis to maintain a great looking lawn. The first application with a suitable fertiliser can be at 10 weeks after application of Miracle-Gro® Thick’R Lawn. Regular feeding with a suitable fertiliser will help keep the lawn thick and healthy.

What about children and pets?

It’s fine to use Miracle-Gro® Thick’R Lawn in gardens with children and pets, but little feet can damage developing seedlings, so it’s best to keep them off the treated areas until the grass has established.

Where to use

For use on lawns.

When to use

From March to September. Miracle-Gro® Thick’R Lawn can be applied in spring once the grass is actively growing and frost has passed.
