Kill Moss in Lawns

Used by Landscape Gardeners Throughout New Zealand to Kill Moss in Lawns

Time to Kill Moss in lawns? Moss needs moisture to grow but can survive periods of drought. It is usually associated with poor drainage, shade, low nutrient level and/or acidic soil. It is low growing and forms a spongy mat.

Since moss thrives in damp soil, it encroaches on areas that have poor drainage and where the soil is compacted. It can be found in almost any damp and shady area of your garden including lawns, garden beds, paths and driveways.

Why Moss Grows in Lawns

The first thing to understand before taking steps for killing moss is that Moss is an opportunistic plant. It will not push out grass or kill plants to take hold. It will simply move into a spot where nothing is growing. Moss in your lawn is normally an indicator that something deeper is wrong with your lawn, and the moss is simply taking advantage of the empty dirt that dead grass left behind. So really, the first step to truly ridding your lawn of moss is to first treat the deeper issue with your lawn.

First, check for the following reasons why your grass may be dying, as these reasons not only kill the grass but create an ideal environment for moss.

Compacted soil – soil compaction kills grass roots and creates a smooth area for moss to hold onto.

Poor drainage – soil that is continually damp or even swampy will suffocate grass roots and also provides a damp environment that Moss loves.

Low pH – Grass needs a moderate or slightly alkaline soil to thrive. If your soil has a low pH and is high in acid, it will kill the grass. Coincidentally, moss thrives in high acid soil.

Lack of sunlight – Shade is notorious for making it difficult for grass to grow. It is also the preferred light for moss.

Solving

It is important to address the causes of your problem to prevent moss regrowth:

  1. Cut back any plants shading the affected area.
  2. Improve drainage in the area, this can be done by aerating the ground with a spike or fork.
  3. If possible, keep off lawn when wet to prevent soil compaction.
  4. Moss growth can be a sign of poor nutrient levels in the soil and high acidity.

How to Kill Moss In Lawns

 

Cut the lawn one day before treatment then spray with Spik & Span. Best to apply in Autumn or early winter before moss becomes too established and dense, though the product can be used throughout the year.

Once sprayed, avoid cutting your lawn for as long as possible to allow the product to take effect. When moss has died, rake out of lawn and reseed lawn if necessary.

Give your grass a better chance to grow and kill the moss in your lawn.

Spray the effected areas of the lawn liberally with a very diluted solution.

If instructions are followed, Spik & Span will not affect the lawn or any surrounding garden plants.

The moss in the lawn will start to turn yellow in 2-3 days, and is usually dead in 2-3 weeks. Lawn, which was suppressed by the moss, will then regenerate for a fuller and lusher lawn.

 

It is recommended to top-dress your lawn with garden lime, once moss is dead, which acts as a soil sweetener and leads to a lusher lawn.

 

If you have pets and young children, allow the Moss and Mould Killer to dry first before allowing them onto the lawn.
