Moss Control

Moss Control - Soluble Iron - Lawn Shop Over the last few weekends, we trust that you have taken time out in the garden and inspected your lawn to see how it has survived the long winter.  No doubt it has thinned and got a bit of moss in it.

Many a lawn treatment company insist on only treating moss in the autumn months which is a load of rubbish as their soluble iron would have only killed the moss that was there at the time not what has established since in the non growing season.  Their actions are also technically incorrect and NOW is the time to control moss in your lawns.

Traditional lawn owners will instantly think of applying Lawn Sand, a blend of Iron Sulphate, Sulphate of Ammonia and Kiln Dried Sand.  It is usually applied at a high rate of 140 grams per square metre and most if the product is sand - almost 70%.  The Sulphate of Ammonia in the product will provide a rush of growth from the 21% Nitrogen and the Soluble Iron some colour and moss darkening and killing.

Soluble Iron is a wet sugar like product that easily goes into solution, especially if using a little tepid water to mix it up before pouring it into your Knapsack Sprayer.  Dependent upon the strength of the Soluble Iron (the percentage of Iron in it) you should aim to use around 1.2 to 1.5 Kg per 15 Litres of spray solution across an areas of approx 500 - 750 square metres dependent  upon the calibration of your Knapsack Sprayer.  At this dose rate, you will get a rapid greening up of the grass and also the moss will be retarded by turning black, drying out and dying.

Leave the lawn for two weeks following treatment with moss killer to ensure the moss is dead before scarifying it out.  Do not forget to aerate the lawn and then fertilise it with a spring and summer fertiliser and over seed it totally to get some more grass seed into the surface. 

If you lawn has lots of moss in it, you will never grow any grass amongst unless you are cruel to be kind - kill the moss off totally and then renovate your lawn.

Soluble Iron may be applied monthly over the lawn at half the moss dose rate to keep the lawn looking nice and green and if you spot some moss creeping in, up the rate to blacken it off.  If your lawn has dense healthy grasses in it, the moss will not get a look in and moss is mostly an indicator telling you that your lawn's condition is poor or it is struggling to grow in the area you are expecting it to such as in dense shade, north facing and under fence lines and hedges.
