When to apply a fertiliser

  • Fertiliser should be applied in the spring/summer and autumn months
  • It’s a good idea to wait for three days after mowing your lawn before applying the lawn feed
  • Apply when the soil is moist
  • It’s best if lawn feed is applied when rain is expected

How to apply a fertiliser

Always follow the manufacturer’s instructions for spreading rates.

Mark out sections of your lawn with pegs or string in one metre squares. This will help you to apply the correct amount of lawn feed in each square metre. While wearing suitable gloves sprinkle the fertiliser evenly, one square metre at a time, until you have covered the entire lawn area. Take care not to apply too much fertiliser, as you could do more damage than good.


If it doesn’t rain after a couple of days, water the lawn well with a sprinkler or hosepipe on a gentle setting – this will allow the fertiliser to start working. Try not to walk on the lawn until the feed has dissolved into the turf, and don’t mow the lawn for at least three days after you have applied it.

Your lawn will start to look greener and healthier after approximately seven days. Don’t panic if you see parts of your lawn turning black – this is the moss dying; it can be easily raked out and disposed of. Weeds develop a growth spurt shortly after fertiliser is applied, but will soon die off leaving your lawn weed-free.


Never use a spring/summer lawn feed after the month of August as these fertilisers contain high levels of nitrogen which encourages fast, leafy growth. Autumn feeds contain high levels of potash and phosphates which will strengthen the grass, prepare it for the colder temperatures of winter, and help to protect it against the onset of lawn diseases.
