Have you noticed a white residue on the potting soil? Are you worried that it might harm your plants? Find out what causes this phenomenon

White scale is a sign that the water you water your plants with is too hard. This is a calcium deposit that can be combated. For starters, stop watering your plants with water straight from the tap. The water you want to water your plants with should stand for at least one day

However, when you put the water off and the white deposit in the pot is not from water that is too hard, the result could be mold.

How can you tell the difference between mould and white deposits?

If you are dealing with mould then you will notice a fluffy and soft coating on the soil. This is actually a compacted mycelium that occurs with numerous spores.

A common cause of mildew is overwatering. This increases the humidity of the substrate and, combined with too high a temperature and a well-lit room, you will create ideal conditions for mold to grow on the ground. Pot mold is more harmful to plants than white residue, so keep an eye on your plants and make sure they are properly watered, but be careful not to overwater!
