What exactly is blue grain?
Blue corn is not a weed killer but a chemical fertilizer that is supposed to make the lawn grow well. It contains nitrogen, phosphate and potassium in varying proportions by weight, often also magnesium and / or other substances. The use of blue grain can therefore lead to over-fertilization, especially if used improperly.

Is blue grain poisonous?
Blue corn is a chemical fertilizer that can be classified as harmful to humans and animals. If it comes into contact with mucous membranes, it irritates them. This also happens when your pet walks on the freshly fertilized lawn and then licks its paws.
Therefore blue grain should be washed into the ground as quickly as possible. If it does not rain in the days after fertilizing, you should water your lawn or set up a lawn sprinkler (€ 27.94 on Amazon *). Do not let your children play on the lawn or let your animals run free during this time.
What can I use instead of blue grain?
Moss likes neither alkaline soil nor sun, so it mainly grows where it is shady and the earth is rather acidic. So if you see moss on your lawn, it is probably in the shade and the soil has an unfavorable pH level. Scarifying removes moss and aerates the soil. Sulfuric acid ammonia has a beneficial effect on the soil climate.
The most important things about blue corn in brief:
- not a weed killer but chemical fertilizer
- available in liquid form or as granules (blue beads)
- irritates the mucous membranes when he comes into contact with it
- should be washed into the ground as soon as possible (by rain or watering)
Tips
If you have small children or pets who like to run around on the lawn, you should not use blue grain if possible. It is not entirely harmless.
