Usually, the soil of your plants is brown, but sometimes a white layer can form on its surface.
There are two possible causes for this to happen:
1. Deposit of salts
When you water your plants, either because of the water quality or because of the fertiliser you are using, salts can be deposited on the surface of the soil, creating a harder and drier crust. You must remove this white layer as it appears, water, if possible, with distilled water, and use our Soil Booster to naturally fertilise your plants.
If, on the other hand, this white layer is damp and somewhat spongy, they are most likely fungi that naturally exist in the soil, but which, due to humidity and temperature conditions, which are usually high, develop more. You should prolong the period between waterings more, remove this superficial layer, and spread a little of our Soil Topper.
