The Best Moss Killer: Our Picks
Guide: Questions you should ask yourself before buying a moss killer
Who is a moss killer suitable for?
Moss has existed for 450 million years, making it one of the oldest plants on earth.
Unlike conventional plants, moss does not spread by seeds but by spores. It is therefore able to fertilise itself for the most part. This is why moss can spread so quickly.
In addition, moss prefers habitats that are otherwise colonised by almost no other plant. Moss prefers shade, can survive long dry periods, but in return has no problems with persistent wetness.
While moss is an important component for flora and fauna in the forest as protection against the drying out of the soil and is quite beautiful to look at, it can become a danger of injury on footpaths due to slipping.
It is also unsightly on house walls, on roofs or between lawns. Once moss has sprouted, it is difficult to control. A moss killer can provide practical help here.
Moss does not give the lawn a chance to flourish and will grow out faster and faster.
Why do I have moss in my garden?
Moss on lawns can also indicate waterlogging. This is usually associated with soil that is too compacted. The water is therefore unable to drain away.
Moss on house walls, walls or on pavements is also usually caused by shade. Does the affected wall face north? Or are there trees and other bushes in front of it that cast shade and prevent drying?
Infestation on pavements is also usually due to shade or the always cool wet joints. These are optimal living conditions for the moss plant. The reasons for moss infestation at a glance:
|Lack of nutrients in the soil||Fertilise the soil|
|Over-acidified soil||Lime the lawn|
|Too little light||if necessary. Cut down trees/shrubs|
|Heavy, compacted soil||loosen soil|
|Waterlogging||regulate watering, loosen soil, provide more sunlight|
|No regular mowing||mow lawn at least once a week|
|Mowing too short||do not mow shorter than 5 cm|
|Unsuitable seed mixture||do not use cheap seed|
How to apply moss killer on lawn?
- First you should mow the lawn.
- Wait 2 - 3 days so that the cut wounds on the blade of grass can close.
- Apply the moss killer in the morning when the lawn is still damp from dew. It should be a day without rain.
- The death of the moss is indicated by a brown discolouration.
- The dried moss can be removed with a rake.
- New grey can be sown in the areas that have become free.
- The lawn must not be mown again until 7 days after using the moss killer.
What are the alternatives to a moss killer?
It is forbidden to use weedkillers on the pathway, because the harmful substances can be washed into the groundwater!
However, there are certain moss removers that are specifically approved for patios. Moss in the lawn or on beds can either be cut out or removed with a scarifier. Depending on how large the infested area is, however, this is a real back-breaking job. The few steps of removal with a moss killer, on the other hand, seem more comfortable.
Decision: What types of moss killers are there and which one is right for you?
If you want to buy a moss killer, there are three different types to choose from.
- Moss killer with iron fertiliser
- Moss killer with quinoclamine
- Vinegar or salt as moss killer
What distinguishes a moss killer with iron fertiliser and what are its advantages and disadvantages?
A moss killer with iron fertiliser usually contains iron II sulphate. This is not only recommended as a moss killer, but also as a lawn fertiliser.
An iron deficiency in your lawn is manifested by yellow discoloured blades. Unlike grass, moss does not tolerate iron and therefore dies.
After applying the moss killer, it takes about 7 days until the moss turns brown and dies. You can then simply remove it with a rake. The iron fertiliser contains valuable minerals for the soil. These minerals help the lawn to a lush green appearance and fast growth, as the root system is strengthened by iron.
Moss killer with iron sulphate reliably removes moss for two to three months.
Note that the oxidising iron will cause brown stains on objects that come into contact with it. When spreading the moss killer with iron fertiliser, make sure that it does not fall on paving stones.
There are special spreaders with which the moss killer can be applied evenly and without constant contact. You should also wear old clothes and shoes, as these can also become discoloured. Frequent application of moss killer with iron-II-sulphate leads to over-acidification of the soil and thus also damages other plants.
Caution! Iron-II-sulphate is corrosive.
Be sure to wear protective clothing. In case of contact with the eyes, rinse the eye immediately with water. You should also consult an ophthalmologist to be on the safe side. The reaction of the iron-II sulphate can also release toxic fumes.
For this reason, it may be advisable to wear a respiratory mask when spreading the fertiliser. Iron fertiliser is usually available as granules in small pellets. Therefore, after spreading, make sure that children or pets do not ingest them.
The lawn can only be walked on without hesitation after 10 days and repeated watering in of the moss killer.
Moss Killer with Iron Fertiliser is a simple and effective way to remove moss from lawns and maintain the lawn at the same time. If you want to control moss in the long term, you should use additional measures such as regular mowing, aerating the soil and watering.
What distinguishes a moss killer with quinoclamine and what are its advantages and disadvantages?
Moss killers with quinoclamine consist of a chemical compound that prevents photosynthesis in mosses. For this reason, these preparations also prevent the spores from germinating.
The effect becomes apparent after approx. 5 days. Here too, the dead moss can simply be removed. After a single application, the lawn is moss-free for up to 5 months.
One advantage of these moss killers is that they can be used all year round. In addition, this moss killer attacks almost no other plants. Quinoclamine moss killer must not get on the skin. It is less harmful than iron fertiliser, but protective clothing should still be worn when applying it.
The moss killer with quinoclamine removes moss easily and effectively. It is a good alternative to the much more harmful iron fertiliser.
What are the advantages and disadvantages of vinegar or salt as a moss killer?
Vinegar essence or salt is often used as a household remedy to combat moss. A 5 - 15 % solution should be mixed and then applied to the infested area.
The solution is most effective in sunlight.
The application of salt or vinegar is completely harmless to humans. However, these home remedies are not really suitable for killing moss. The application damages all surrounding plants. In addition, there is a risk of salinisation of the soil.
Special care must be taken when cleaning stones! Cleaning terraces with salt and vinegar is prohibited if the siker water is drained into the sewage system. If this is not the case, caution still applies to cold stones. Acetic acid attacks lime.
Salt and vinegar are not suitable as moss killers. The negative effects on the soil and surrounding plants do not outweigh the home remedy application.
Buying criteria: Use these factors to compare and evaluate moss killers
In the following, we will show you which characteristics you can use to decide between the possible moss killers. The aspects that help you to compare the moss killers with each other are as follows:
- Time to effect
- Duration of freedom from moss
- Granulate or concentrate
- Danger to humans and animals
- Further care measures
The different types of moss killers differ in the composition of their ingredients and therefore have different advantages and disadvantages, as mentioned above.
Peat moss is used for peat baths as well as peat packs because of its disinfecting properties. In naturopathy, many types of moss are used to make a tincture that is used against inflammations.
The moss killer with iron sulphate is effective in its mode of action, but it is also the most harmful. You must wear protective clothing, it must not get on the skin or in the eyes because the corrosive effect can cause damage. It also leaves unsightly brown stains on stones and clothes, even days after application. It is also dangerous for children and animals.
The moss killer with quinoclamine is a good alternative. It is just as effective, but not nearly as harmful. Moreover, it can be used all year round and does not leave any unsightly discolouration on objects.
Vinegar and salt are not suitable as moss killers. If you want a moss killer that is harmless to children and animals, you can also simply remove the moss with a scarifier. There are also some suppliers who sell biological moss killers.
Time to effect
Moss killers also differ in the time it takes for them to take effect. After application, the moss killer with iron sulphate needs between 5 - 9 days until the moss is dead. The moss killer with quinoclamine needs 3 - 10 days.
Basically, it is said that this moss killer takes a little longer to kill the moss. However, it is not as harmful as the one containing iron sulphate. Depending on how much of a hurry you are in to remove the moss, you can choose one or the other.
Duration of the moss-free period
Another criterion for differentiation is the duration of freedom from moss after application of a moss killer. A moss killer containing iron sulphate will keep your lawn moss-free for 2-3 months after application.
Although it fertilises your lawn at the same time, you should not use it too often, as this will lead to over-acidification of the soil, which will damage the lawn and other plants. Moss killers with Quinoclamin keep your lawn moss-free for 3 - 5 months.
This moss killer does not attack other plants. In principle, however, chemical moss killers are only short-term solutions. To get rid of moss infestation in the long term, the cause of the moss growth must be eliminated.
Granulate or concentrate
When buying a moss killer, you can choose between granulate or concentrate. Both cost about the same and have the same range. The only difference is in the application. Moss killer in granulate form can simply be scattered over the area.
Since care should always be taken to ensure even dosing, it is advisable to distribute the granulate using a spreader trolley. This also has the advantage that you do not have to constantly touch the chemical mixture.
Moss killer as a concentrate must be diluted with water before use according to the manufacturer's instructions. The solution can then be poured into a watering can and distributed with it. Depending on which method of application you prefer, one or the other is more suitable for you.
Danger to humans and animals
A moss killer is usually a chemical product. Therefore, there is always a certain danger for humans and the environment. In principle, the moss killer containing iron sulphate is more harmful to human health than the one containing quinoclamine. However, there is no acute danger if the product is used according to the instructions.
It does not always make sense to destroy the moss in your garden. Mosses have a high value in the ecosystem: they serve as a shelter for beneficial insects, insects find food there and garden birds find material to build their nests.
Just make sure that neither children nor pets walk on the lawn during the first week after application, or eat any of it. In addition, the fertiliser should be stored in a place inaccessible to children and animals.
After applying a moss killer, the substance should be thoroughly watered in over the next few days to allow the lawn to grow in. After that, children and animals can play on it without hesitation.
Further maintenance measures
A moss killer is only suitable for short-term control of moss infestation. Since it is a chemical substance, it should not be used exclusively for moss removal, but other measures should also be taken.
These include regular mowing of the lawn. Once a week is recommended, whereby care should be taken not to mow the grass too short. Otherwise it will dry out and die, especially in hot summers.
The moss will colonise the free area very quickly. You should also water your lawn regularly, but at the same time make sure that there is no waterlogging. It is also advisable to scarify the lawn several times a year.
Facts worth knowing about the topic of moss killer
How do I remove moss from my roof?
Mosses, algae and lichens are always found on house roofs. While there is general agreement that algae and lichens do not damage the roof, opinions differ when it comes to mosses.
As with patios and pavements, high-pressure cleaners or certain steel brushes can be used to remove them. Special chemical cleaning agents are also available from specialist dealers.
Most of these cleaners are based on kufer sulphate and can be applied to the roof with a sprayer. After the time it takes to work, the moss can be brushed off. Remember to clean the gutters and downpipe, otherwise blockages will occur.
To protect your roof from moss in the long term, you can have copper tape laid along the ridge of the roof. Every time it rains, copper ions are rinsed out and distributed over your roof.
Caution! This method should not be used on galvanised gutters, as copper causes zinc to corrode.
Lawn care in autumn
The early bird catches the worm - so start fattening up your lawn for spring in autumn to curb moss growth. During the last mowing in October, the lawn should be shortened once to 5 cm. Stalks that are too long will topple over and rot under the autumn leaves.
Also be sure to remove lawn clippings.
If mulching is good in summer to maintain moisture, the rotting grass cuttings are detrimental in autumn/winter. But if you mow the lawn too short, the roots are at risk of frost damage in winter. Now is the time for a powerful autumn fertiliser.
Fertilisers containing potassium make your lawn fit for the winter by supplying it with important nutrients and lowering the freezing point of the lawn plant. This means that the lawn only really freezes through in sub-zero temperatures.
You should also remove the leaves regularly. With the first rays of sunshine in spring, your lawn will start the new growth phase stronger and thus leave less of a target for moss.
