Every now and then it happens that white mold forms on the surface of potted plants or indoor plants. However, this change in the earth can be remedied with simple means.
If there is mold in the flower pot, repotting is the right measure
Remove and prevent mold on potting soil
Mold on the potting soil is not only bad for the plant. People who are prone to allergies can get sick from the spores buzzing around. So don't smell the potting soil, but rely on your eyes. Mold has a fluffy structure and spreads over a wide area. White lime deposits, which can also occur, are crumbly and dry.
Severe mold infestation can lead to illnesses such as
- skin irritation
- respiratory disease
- difficulty concentrating
- coughing
- asthma attacks
- increased susceptibility to infections
Pets can also get sick from mold spores.
If mold forms on the potting soil, immediate action should be taken. You have to assume that the entire soil in the pot is already infested with mold spores. Simply scraping off the affected surface is never enough.
First aid for moldy potting soil
Spot the telltale white film on your potting soil, act immediately. Take the infested plant outside. If you are prone to allergies, wear gloves and a respirator when you work to avoid inhaling spores.
- Repot your plants
- Use fresh soil
- Thoroughly remove old soil from your plant, wash off the roots
- Clean the flower pot with hot water, soapy water or vinegar water
You should dispose of open-pored pots made of clay or terracotta, as the spores like to nest deep in the porous material.
- Check all other plants for possible infestation
prevent mold growth
If you have repotted your plant in fresh soil, you should definitely prevent a renewed mold infestation. Provide loose potting soil and make sure that there is no waterlogging. Moderate watering and drainage made of gravel or expanded clay help against soil that is too wet.(19.73€)
Make sure the plants get plenty of light, mold loves darkness!
If you like the smell, you can mix a few drops of tea tree oil under the surface of the soil. The oil does not harm the plants, but it does help against mold growth.
If a certain plant is noticed again and again by mold, it must be disposed of. The mold will continue to spread and affect other plants as well. Dispose of the plant and the soil in the residual waste. The mold spores will continue to develop and spread on the compost.
use of fungicides
Fungicides are chemical agents that kill mold. They are given to the earth, but they also get into the plant.
In any case, this "chemical club" should be the very last resort to combat it, because with the chemicals you often bring even more dangerous pollutants into your garden or your home. When used in the home, the agent must be officially approved for living spaces.
