Do you need to lime your lawn?

Most types of lawn grasses grow best in soils with pH 6-7. If your soil is below pH 5.5 (acidic) then your lawn won't grow thick, lush and dark green. Adding fertilizer (N.P.K.) won't help this problem as acidic soils can't absorb the nutrients very effectively.

Some indications that your lawn might need lime:

  • live in rainy area and acidic loving plants such as rhododendrons thrive in your garden?
  • lots of moss growing through your lawn?
  • no matter how much fertilizer you apply, after a couple of cuts grass loses lush green colour again?
  • regularly re-seeding but lawn never thick and lush?

The only way to find out for sure is to do a soil pH test.  Simple kits can be bought at your local garden centre or send a soil sample to your local agricultural college.  Soil test kits will tell you the pH of your soil.  The agricultural college will tell you your soil pH and the quantity of lime required to raise the pH to an optimal level for your lawn (tonnes/hectare).

Amount of lime to apply?

The amount of lime to apply is not only determined by soil pH but also by soil type.  Heavy clay soils require more lime to raise it by 1 level than compared to sandy soils.  See the table below for general application rates:

 Clay Soil Original pH Kg/m2
6.0 0.6
5.5 1
5.0 1.4
4.5 1.8
 Loam Soil Original pH kg/m2
6.0 0.5
5.5 0.8
5.0 1.2
4.5 1.5
 Sandy Soil Original pH Kg/m2
6.0 0.4
5.5 0.7
5.0 1.0
4.5

When to lime?

Many gardeners prefer to lime in the autumn before the first frost. This gives the soil all winter to absorb the lime.  If you haven't sown your grass seed apply lime to the soil while preparing it, best to have it mixed in before your roll the ground before seeding.

You should see a measurable difference in your soil pH around 4 weeks after application, but it can take 6-12 months for the lime to fully dissolve.  You won't see the full effect until it is completely incorporated with the soil.
