The appearance of foam is favored by many conditions. If we are not careful, it gradually invades the lawn and harms the aesthetic appearance of the garden. However, there are effective solutions to have a beautiful lawn all year round. Here is what the gardener must do in order to permanently eliminate moss from his lawn and the solutions to adopt to prevent rather than cure.
What promotes moss on the lawn?
The factors favoring the development of foam are as follows:
- A acid earth,
- A poorly drained soil, which therefore remains wet too long since rain or irrigation water does not flow well,
- A land not very fertile, deficient,
- A grassed area too shaded, critically lacking in sunlight,
- A poorly ventilated ground,
- Of too shaved clippings,
- The poor general maintenance of the lawn,
- The trampling intensive turf because it hardens the soil. This is undoubtedly one of the main factors favoring the development of moss, especially if it is associated with high humidity and the soil is clayey, because the more compact the soil, the more likely the moss is to appear.
When moss invades the lawn, action must therefore be taken on all fronts to get rid of it.
Remove moss from grass by tackling the cause
There was a time when people weren’t always concerned about the safety of a defoamer, and turf was treated with iron sulphate because it made the foam disappear quickly. However, we now know that this is not the best solution because, in addition to being irritant for the skin and eyes but also toxic to the body, by increasing the acidity of the soil, iron sulphate promotes the return of moss.
We now understand that it is not enough to treat to temporarily remove it, but that it is essential to tackle the cause of its development in order to be rid of it in the long term, and without danger.
So that the lawn regains its original beauty and is completely free of moss, it is necessary to draw up an inventory and identify the cause (s) of the problem in order to resort to the appropriate solutions.
- Analyze the soil in order to know its pH (hydrogen potential) which is most certainly of the order of 6.5 or even lower. It means the earth is acidic. If so, it is necessary to lower this acidity rate thanks to natural solutions such as, for example, the addition of wood ash or lime.
- Fill the deficiencies possible in potash, magnesium and calcium since they promote the development of foam. A contribution of rock powder is welcome in this case.
- Add some sand if the earth is too heavy and quickly becomes compact, because this material allows to lighten it.
- Avoid stomping too much the grass if it is not intended for heavy traffic.
- Mow the lawn regularly, always taking care adjust the cutting height to 5 or 6 cm. The grass should not be shorter than this.
- Proceed totree pruning if they provide too much shade to the lawn or implement any possible solution to promote its sunshine.
- Perform a topdressing, an operation which consists in spreading directly on the lawn a layer of soil of the order of 5 to 10 millimeters. An excellent result is also obtained with a compost type fertilizer. Composting has different benefits, to know :
- Lighten the earth,
- Improve the soil structure,
- Allow better retention of rainwater and irrigation,
- Increase the porosity of the soil, which is positive for the development of the roots of the plants that make up the lawn, thanks to the gas exchanges which are amply favored.
We can take out a maintenance contract with a landscaper so that he himself takes care of the maintenance, even the restoration of the lawn. The operation does not cost as much as you might think since it is possible to benefit from a significant tax advantage by entrusting this type of gardening work to a professional.
Preventive actions against lawn moss
You should not count your time if you want your lawn to take on the appearance of golf green of a stunning beauty. And we can avoid seeing it invaded by moss by using natural means of prevention within everyone’s reach, namely:
- When preparing the land on which you plan to sow grass, install a drainage system composed of several looks when necessary.
- Reserve the most shaded parts of the garden at the growing flowering plants who do not like full sun rather than sodding them because it will be difficult to avoid the appearance of moss or else it will be necessary to spend a lot of time to fight against this invader which loves the shade.
- Fertilize regularly because moss proliferates in poor soils. We favor organic organic fertilizers. But we stop all fertilizer application between June and the end of September and only start again in the fall, which will help the lawn to be more resistant to face winter.
- Scarify with a manual or motorized scarifier since the rotary knives and teeth of this device allow:
- Unpack the earth,
- To aerate the ground,
- To tear off the old thatch,
- To lacerate the foam which we are then rid of.
These actions increase the lawn resistance which stays beautiful and prevents moss from growing again.
Finally, before sowing your lawn, we must always choose its category according to its use. For example, it is better not to transform it into a playground or sports field if you have not chosen a seed resistant to intensive trampling. There are specific lawns for this type of activity because they cannot be snapped up. They combine, for example, fescue, perennial ryegrass and meadow bluegrass. Sown in a slightly acidic, well-drained and humus-bearing soil, on a sunny, regularly aerated ground but also on the condition that the lawn is not mowed too short, not only will it remain beautiful despite the trampling, but in addition it will not be invaded by the foam.
