White coating in pots is not only an aesthetic problem. It is also a signal that we make some mistakes in the care of our plants. Therefore, it is worth knowing what its appearance means and what are the causes of its occurrence. We tell you how to recognize the type of coating and what to do to get rid of it effectively.
In autumn and winter you can often observe a white coating appearing in pots. This is because During this period, plants have less light, so evaporation is much weaker. However, it does not always mean the same thing.
When the shade of the coating is slightly yellow, it may be a signal that… we use too hard water for watering. It causes limestone particles to settle on the ground. This is quite a common problem that we can easily solve.
All we need to do is remove the top layer of soil, removing only 1-2 cm of soil. Then add some fresh mixture and wipe the edges of the pot inside and out a solution of vinegar and water in a 1:1 ratio. Finally, rinse the container with plain water.
Of course it is also necessary cessation specimens using a hard liquid. Instead, we should use settled water. We should also remember to limit fertilization when dealing with white salt coatings.

Sometimes, though white coating may indicate more serious problems, namely mold. We can easily recognize it because it creates a soft and fluffy eiderdown. This is where mycelium and spores accumulate. Mold is usually the result of too much watering of plants, poor air circulation or too high a temperature in the room.
After noticing the problem, you should limit the frequency of watering your specimens. In addition, we also need to ensure proper air circulation in the room. Then, as in the case of white coating with hard water, we must remove the top layer of soil. But this time we replace it not with a mixture, but with quartz sand or a thin layer of gravel. This will make it dry much faster.
Using cinnamon would also be a good idea. All we have to do is sprinkle it in a pot to get rid of the mold and prevent its return. This is because this spice has bactericidal and fungicidal properties.
