Types of moss killers with long-term effects

our recommendation
COMPO lawn moss-free Herbistop, combating moss and algae, concentrate, 500 ml
9.95 EUR To the product

Of course, if you are already removing the moss from the green carpet in your garden, the effect should ideally last for a long time. Not all commercially available moss killers (€15.29) meet this criterion. Only when using products with

  • quinoclamin or
  • ferrous sulfate

as the main ingredient, the lawn remains moss-free for at least three months.

Quinoclamin moss destroyer in a short check

Quinoclamin inhibits photosynthesis in mosses to such an extent that their metabolism is impaired and they die after about ten days. The other plants around it are spared.

Caution: The agent not only destroys moss, but unfortunately also irritates. Therefore, you should always wear protective goggles and protective gloves when applying the moss destroyer.

Quinoclamin gives moss no chance for up to five months.

Iron sulphate moss destroyer in a short check

our recommendation
25 kg iron fertilizer 20% iron sulphate
25.79 EUR To the product

Iron(II) sulphate is the most widely used active ingredient in moss killers and is a moss fighter and fertilizer in one.

  • Iron strengthens the root system, thus promoting lawn growth and lush green stalks.
  • Moss does not tolerate ferrous sulfate. It dies after about seven days.

Caution: Iron(II) sulphate mercilessly leaves unsightly rust stains on objects with which it comes into contact. In addition, the active ingredient is corrosive and sometimes releases toxic fumes.

Our advice: wear old clothes and shoes, safety goggles, a respirator and gardening gloves when using it! Also important: You should not use moss killer with iron(II) sulfate too often (overacidification of the garden soil).

Iron II sulfate works for two to three months.
