Problems With Moss

The main reasons for moss appearing in lawns are:

(1) Waterlogging; continually wet patches almost always develop moss
(2) Underfeeding of grass
(3) Overacidity (Low lime level)
(4) Too much Shade
(5) Cutting the grass too short.

Moss Control
The best time to get rid of moss is in spring, when the moss is soft and spongy not dry and hard like it gets later in the summer, if we get a summer.

There are a few choices for the control of moss

(A) Special Lawn Fertiliser ….Feed the lawn with OSMO Moss Remover
Six simple steps to a moss free lawn using OSMO Moss remover.
1. If possible cut your lawn a couple of days before applying OSMO Moss Remover, this will make it easier to apply evenly to the 180 sq meters lawn area.
2. Mark out 180 sq meters (Approx 18 meters X 10 meters) using a cane or marker to identify the area to cover.
3. Apply a dressing of OSMO Lime Pellets one to three weeks before you apply OSMO Moss Remover – each bag covers 250-500sq meters. Best spread in dry weather.
4. Apply OSMO Moss Remover granules evenly through a lawn spreader to 180 sq meters. Please ensure the granules are applied evenly over the entire 180 sq meters area only as spreading over a larger area will dilute the effects of the moss control and feeding.
5. OSMO Moss Remover firstly kills the roots of the lawn moss, the moss goes yellow and dies within a 3 week period (depending on weather). The fertiliser will green your lawn within 2 weeks of application and feed the lawn for up to 3 months.
6. Remember to feed your lawn in mid-summer with a second dressing of lawn fertiliser

(B) Lawn Sand….This will burn out the moss and also effectively provide a boost for grass growth.

The active ingredients in lawn sand are
1. Ferrous Sulphate, which kills the moss, and
2. Ammonium Sulphate, which gives the grass a rich green colour.
3. It is a good idea to apply lime to the lawn a few weeks later to increase the ph level in the soil for more efficient uptake of fertilizer and making soil less friendly to moss.
(C) Sulphate of Iron (Ferrous Sulphate) on its own. This kills the moss. Apply at a rate of
1 bag of 25kg covers about 800 sq meters.
After using either treatments, do not walk on the lawn until after rain has fallen or until it has been

Two Days after Treatment Thoroughly water the lawn if rain has not fallen since application.

Three Weeks Later: Scarify (Rake Out) all the dead moss. If there is a large area of dead moss
(thatch), you can hire a powered scarifier from your local plant-hire dealer.

Feed the lawn thereafter, Regular feeding in spring and early summer is vital to keep grass
growing strongly. Humber Palmer Fertiliser is best fertilizer for lawns. It is also advisable to add lime every few years unless you are in a limey area.

Reduce Shade, if possible. Removing lower branches may help, but moss is usually unavoidable in
grass growing under trees.

Scarify and Aerate the lawn. Removal of the surface mat by raking, and improvement in drainage
by spiking are important operations in a moss control programme.

Where a large amount of thatch has been removed it will be necessary to sow grass seed in bare
areas. Use Delux No 2 Lawn Seed Mixture.


The appearance of clover in grass is encouraged by a shortage of both water and nitrogen.
To reduce the amount of clover, feed the lawn with a nitrogen-rich fertiliser every spring.
If you have a problem with Clover do not use a phosphate- or potash-rich fertiliser at the start of the growing season.

Use a selective weedkiller, i.e. a weedkiller that will kill clover, but not grass.

Weedkiller for Lawns

Use selective weedkillers on lawns. These are selective in their action, killing susceptible weeds
but not affecting other plants, such as grasses, when used at the recommended rate.
An example of a selective weedkiller is Dicophar. This kills weeds, while not affecting the
grass. It should be used from April to June for best results.

Do Not Use selective weedkillers on new lawns. If there are weeds in a new lawn you should wait
for twelve months after sowing lawnseed before applying a selective weedkiller.

After treatment of established lawns, bare patches may appear, once large clumps of weeds have
died back. These patches can be re-seeded six weeks after treatment.

AllinOneLawnAll in One Lawn Feed and WeedkillerAll in One Treatment – Weed, Feed and Mosskiller
If you have weeds in your lawn the easiest method of treatment is to use an All in One treatment for your lawn.
Aftercut All in One is a multi-action lawn treatment that not only feeds and conditions the lawn, it also kills weeds and moss.

Do not mow the lawn for 3-4 days before or after applying All in One treatment. Best applied on a calm dry day onto dry grass, when rain is expected. If it does not rain within 48 hours of application, you should water the lawn to activate the treatment.
