Treatment of Moss in Lawns - Lawn Moss Killer - How to prevent Moss in your
Lawn Moss Treatment
Moss in Lawns is probably one of the least understood of
all grass lawn problems. Treating or killing the moss is not the answer.
Moss is a sign that something is basically wrong with your lawn. Too often,
gardeners attempt to kill moss in lawns without tackling the problem that
actually causes it. They are helped to this decision by the huge range of
'moss killers' and Lawn Moss Treatment available at local garden centres.
There are two basic lawn moss killers for lawns that are
available - Ferrous Sulphate and Dichlorophen. One or the other is usually
incorporated into typical lawns Feed and Lawn Moss killer combinations.
is also available as a ready to use 'Moss Gun' for small patches. Neither do
anything by way of treating the basic problem of moss in lawns. They simply
are simply Lawn Moss Treatments - killing the moss which is there. It will return. You can also
use lawn sand.
If you really want to eradicate moss from your lawn, then
you have to find out the actual problem that is causing it, rather
than just treating it. The reasons are various, but not too difficult to
They can be one or several of the causes outlined below
- Waterlogging - in winter or summer.
- Poor feeding regime - usually denoted by light green
- Acid soil - carry out a test.
- Shaded Lawns - overhanging trees or large shrubs.
- Mowing lawns too close - a common cause, for it weakens
the grass - allowing moss to take hold
- Drought - if severe enough to harm or kill the grass.
Not to be confused with a bit of summer-browning
- Sandy - free-draining soils. This can weaken the grass
and allow moss to take over. Some mosses are quite happy in these
- Compaction - continued use by children and pets with no
remedial attention by way of aeration in the Autumn.
Simply using Lawn Moss Killer, will only kill off the current growth. You
should aim at dealing with the basic problem.
Generally, lawns that are well maintained - which includes
being well fed, cut properly, aerated and not allowed to develop thatch -
then the problems which result in moss will not occur in the first place.
Moss can rarely compete with strong growing grass in lawns. It is allowed to
develop and take a hold when the grass growth is weak. Get the grass growing
properly and the likelihood is that your lawn will not suffer from moss
Treating small areas of lawn moss can be carried out with
a lawn moss treatment or lawn moss killer containing Dichlorophen. After a couple of weeks, you can rake
out the dead moss and re-seed. If you need to use a feed for the area, it is
better to feed the whole lawn in order to avoid patchiness!
Assuming that you have inherited a lawn with a moss
problem, you should carry out the following maintenance regime - rather than
simply treating the moss which is there. (The details of all operations are
to be found elsewhere in this section. Quick fixes just do not work, other
than to kill the moss which is present.) Unless you tackle the underlying
problem, the moss will return!
Seasonal Care and Lawn Moss Treatment
Spring Lawn Moss Treatment
In Spring, apply a Ferrous Sulphate based moss-killer
to the whole affected area. Or you can use Lawn
- Two weeks later, rake out the dead moss.
- Re seed the bare areas.
Summer Lawn Moss Treatment
Early Summer, apply a lawn fertilizer to get the grass
- Mow the lawn properly, regularly, throughout the summer
- NOT too short
- Keep the lawn well watered i n drought conditions to
allow the new grass to keep growing.
- Take note of any areas of dense shade on your lawn, and
try to minimize this if possible.
Autumn Lawn Moss Treatment
In Autumn, give the lawn a good raking or mechanical
scarifying, and aerate.
Apply top dressing
at this time if the lawn is either uneven, or in need of an organic
'injection'. Particularly useful on weak sandy soils.
- Carry out a soil test at some stage in the
summer/autumn to assess the acidity of the soil. If in need of adjustment,
then lime can be applied in the autumn.
Winter Lawn Moss Treatment
- Keep off lawns in the winter months in order to avoid
compaction of the surface.
If by the autumn, your lawn is growing well, then most if
not all of the moss in your lawn will have been controlled or even
eradicated. Further spot treatments may be needed, or maybe even a full
treatment for most lawns again the following spring.
Dry Soils and Moss
- Dry soil is susceptible to mosses which tend to grow in
upright habit with small leaves.
- Damp, compacted and waterlogged lawns usually results
in mosses that have a creeping habit.
- Cushion habit mosses usually state that you are mowing
the grass too short.

First signs of moss taking hold in this generally uncared-for
lawn. It has a build-up of thatch, and has been lacking in proper care and
attention resulting in poor grass that leads the way open to moss taking
over. The maintenance regime as outlined above for moss in lawns would do
much to alleviate this problem.
Moss in Turf
If you are buying turf from a turf supplier, you should unroll the
turves and inspect for any signs of mass in the turf. If there is any trace
of moss in the turf, then it is a sure sign that there will be other
problems with the turf as well, and basically it has not been grown with the
care and attention you should expect!
Simply treating or killing the moss in your lawn is not
By far the best Lawn Moss killer Treatment is to make sure that your grass is
