Why overseed your lawn?

Overseeding should follow the removal of weeds and moss and the scarifying of a tired lawn. It will top up bare patches and give your grass a boost. It is best to consider overseeding your lawn during September as an autumn renovation job. If this is not possible another beneficial time is during April or May as a spring renovation.

How to overseed

  • Remove moss and weeds - you can remove weeds by using a spray weedkiller if weeds only appear in certain spots. You can scarify to remove moss if it is in certain areas. If there is moss and weeds throughout the lawn and your lawn is 6 months + old, then our Feed, Weed and Moss Killer product will be most effective.  This product works over two weeks to eradicate weeds and moss - before sowing ensure your lawn is scarified to remove any extra thatch.
  • Now that your lawn is weed, moss and thatch free you should mow it as you won't be able to for 6 weeks whilst the new seed is establishing.
  • Select the correct seed mixture and the correct amount for your needs - you'll need 35g per m2 to overseed.
  • You can sow by hand, or use a spreader if you wish.
  • Water the new seedlings daily for the first 6 weeks after sowing - once the new grass is established (hitting heights of 5-7cm) it is ready for its first mow.
  • Mow the entire lawn (old and new grass) on the highest setting on your mower before dropping to the recommended height for your mix.

Depending on the time of year, apply an Autumn/Winter fertiliser or a Spring/Summer fertiliser around a week after sowing the grass seed to give your lawn a good boost.
