If more moss than grass grows on the lawn, then that is neither nice nor useful. If you don't intervene, the moss will spread unhindered and displace the grass more and more until there are none left.
How does sulfuric acid of ammonia help against moss in the lawn?
Using sulfuric acid ammonia against moss is effective because it is a fertilizer that strengthens the lawn and deprives moss of its livelihood. It is important to test the pH value (€15.00 on Amazon) of the soil before use and to ensure there is enough sun on the lawn.
Iron sulfate is often offered to combat it; it is cheap and seems to work quickly. However, appearances are deceptive, as iron sulfate is highly corrosive and harmful to the he alth of humans and animals. It also makes the soil acidic - good for the moss and bad for the lawn. It is better to use sulphate of ammonia.
What is sulfuric ammonia anyway?
Sulfuric ammonia is not a weed killer, as you might think, but a fertilizer that contains ammonium nitrogen and water-soluble sulfur. The combination of these two substances ensures that the fertilizer is not easily washed out even when moisture persists and enriches it with nitrogen and sulfur. This promotes the growth and he alth of the lawn and moss or clover no longer has a chance or livelihood.
What should I consider when using sulphate of ammonia?
Sulfuric ammonia lowers the pH in the soil, so it should only be administered if the pH is too high or in the upper normal range. If the soil becomes too acidic, grass grows less well, but moss or clover grows all the better.
Therefore, it makes sense to test the pH value (€15.00 on Amazon) of the lawn soil before administering sulfuric acid of ammonia. By the way, this test should also be part of regular lawn care in spring. Then you can react before moss spreads on your lawn.
What else will help my lawn?
Provide as much sun as possible on your lawn, then the lawn grass will thrive much more vigorously. Ground cover plants are much more suitable than lawns for shady and damp garden corners. Maybe rethink your garden planning.
The most important things in brief:
- do not use toxic iron sulfate
- Test soil pH
- Use sulfuric acid ammonia in a targeted and well-dosed manner
- Loosen moss by scarifying
- Drain the floor if possible
- no shady plants on the lawn
Tip
Moss feels particularly comfortable on moist ground and in the shade. If you deprive it of its livelihood, then your lawn will grow better.
