If you’re watering and fertilising properly but your lawn is still brown or patchy there may be other problems

lawn not responding to fertiliser - incorrect soil pH
Lawn with incorrect soil pH

One of the main causes of lawn not responding to fertiliser is the pH level or your soil being too high or too low. In order for the lawn roots to take in nutrients the soils pH needs to be between 6 and 7. Anything outside of this and the lawn will struggle to absorb the goodness from fertilisers.

Test the pH of the Soil

Head down to your nearest Lawn Solutions Centre or local garden centre and pick up a pH soil testing kit. They’re easy to use and come with instructions.

Take a few random soil samples from different parts of your lawn and mix them together. Use the pH test kit to get an average reading.

If soil pH is too acidic (below 6)

When the soil is too acidic you should apply a lime based product or a 50/50 mix of lime and dolomite to the lawn.

If soil pH is too alkaline (above 7)

When the soil is too alkaline you should apply a sulphur based product such as ‘sulphate of ammonia’.

All of the soil pH balancing products are readily available at your nearest Lawn Solution Centre or local garden centre. Make sure you have a chat with them about the current pH of your soil and let them advise you on how much lime or sulphur to apply to bring the pH back between 6 and 7.

If soil pH is between 6 – 7

Assuming you’ve done the pH test correctly and the result shows that the pH of the soil is between 6 and 7, then there may be other issues with your lawn that are stopping the roots from absorbing nutrients.
