The most common type of mold that affects houseplants is called powdery mildew. It appears as a white or gray powdery substance on the leaves and stems of plants. There are also other types and problems that cause mold. It usually looks like white lumps that appear literally overnight. And everything happens because of the contamination of the soil by microorganisms, which are very fond of it for its fertility and richness of useful elements. Improper care of the plant can also lead to the appearance of mold

What causes mold to appear on the soil of houseplants

Excessive watering

Overwatering a plant is a major cause of mold on the soil. Sick soil is very attractive for mold to develop, so do not overwater the plant. The first step in solving this problem is to let the soil dry out completely before watering again. House plants should be watered based on their type so that you can properly care for them and not harm them.

Well-drained soil, as well as peas with drainage, ensure the efficient passage of water through the entire root system of the plant, without its retention. If the drainage is poor, even infrequent watering can cause the plant to develop root rot and mildew. This is due to water standing in the soil and not leaving it.

Soil problems

Plant soil should be clean and rich in nutrients. If you dig up soil in your garden, various microorganisms may have gotten into it, which will later lead to mold. Do not take soil for houseplants from areas where animals walk, and the area is not treated by anyone. It is better to buy ready-made soil for your plant species at a specialized horticultural store. Such soil will immediately include many micronutrients and beneficial substances that will help nourish your plant.

Powdery mildew is one of the most common diseases that can affect houseplants. It is similar to a white mold that affects the stems and leaves of a plant, but it can also be found on the soil. The disease is caused by sudden changes in temperature and high humidity. Various insects carry the disease, or the soil in which the flower was planted was previously infected by another diseased plant. The disease is treated with 5 grams of soda ash mixed with 1 liter of water. Then add 5 grams of soap shavings to the solution and treat the entire plant well with the solution. Repeat after a week.

Disruption of ventilation

Sometimes the presence of mold on plant soil can be an indicator that your home has ventilation problems. If you notice mold on plant soil in your home, it’s worth checking the vents to make sure they are clean. Poor ventilation can lead to moisture buildup, which in turn can lead to mold growth. Also, the plant should not be covered from draughts or cold, during the winter with a dense and unbreathable material. This can lead to the development of mold.

Trash in the soil

If you do not take care of the soil in which the plant is, it can get mold. This is caused by the accumulation of debris when the leaves fall off and are not picked up. After watering, the fallen leaves will moisten and decompose faster. Under such conditions, mold will appear very quickly, taking over almost the entire flower or plant.

Sunlight will help the soil dry out and keep it moist, and fresh air will increase the circulation of oxygen in the soil.
