When caring for houseplants, it’s common for a white layer of mold to form on the surface of the potting soil. Not only is this visually unappealing, but it can also be harmful to the plant’s health. Experts recommend removing the mold and then treating the surface with a simple kitchen spice.
Why does mold develop in potting soil?
The primary cause of mold growth is excessive moisture. If the soil is too wet and there’s insufficient airflow, it creates an ideal environment for mold fungi. Additionally, poor-quality soil or nutrient-rich soil can also contribute to mold growth.
How to remove mold using home remedies
First, carefully scrape off the moldy soil from the surface! Be cautious not to harm the plant’s roots.
To prevent mold from recurring, you can sprinkle cinnamon on the soil’s surface, as suggested in an article by BUNTE.
Cinnamon has natural antifungal properties and helps prevent mold growth.
Control your watering
Reduce the frequency of watering and make sure there’s proper drainage at the bottom of the pot! Avoid water pooling in the saucers beneath your pots.
Improve ventilation
Ensure there’s sufficient airflow around your plants! Place them in well-ventilated areas and avoid overcrowding them.
By following these simple steps, you can effectively get rid of mold and ensure your plants remain healthy and beautiful.
What type of soil is suitable for which plant? We’re here to tell you!
Potting soil can consist of humus, sand, peat, stone fragments, clay, bark, compost, perlite, coco coir, etc. The proportion of these components determines the soil’s acidity (pH) and compactness. When it comes to pH (i.e., its chemistry), three main soil types can be identified (acidic, neutral, and alkaline), each requiring specific pH levels depending on the plants.
A = Acidic soil (pH = 5.9-6.4)
Ingredients: acidic peat, compost, basalt, sand. Acidic potting soil is preferred by plants with low lime requirements: woodland flowers, Norfolk Island pine, ferns, bromeliads, begonias, cyclamen, hydrangeas, and rhododendrons.
B = Neutral soil (pH = 6.5-7) or general-purpose potting soil
Ingredients: natural peat, compost, basalt, sand. This type of soil is also known as universal potting soil and is suitable for most houseplants.
C = Alkaline soil (pH = 7-7.5)
Ingredients: natural peat, compost, basalt, crushed limestone. Mildly alkaline potting soil is often chosen for plants such as oleanders, geraniums, rosemary, and carnations.
Nutmeg soil
This is a mild alkaline potting soil and, as the name suggests, is the best choice if you’re looking to repot your geraniums.
Specialized potting soils
There are certain unique plants and trees that require special soil tailored to their specific needs.
