Practise Good Watering Habits

Watering is an essential process in maintaining the health of your plants. However, you need to water them properly to keep them from fungal infections. For best watering practices:

  • Avoid watering the plants directly into the leaves. Instead, water the soil.
  • Water your plants early in the morning or late in the evening so that they can be able to absorb all of it before nightfall.
  • Do not overwater your plants. Overwatering plants is the leading cause of fungus gnats
  • Use clean water when watering your plants. Contaminated water can spread fungal spores to the plant and cause an infection.

Avoid Crowding Plants

When growing plants, avoid planting them too close to each other. Crowding makes it difficult for light and air to circulate in the plants. Poor air circulation can cause the foliage to remain humid for long hours, a perfect condition for a fungal infection to thrive.

Plant your plants in an area where they will get adequate sunlight. Sunlight helps to dry the leaves and discourages fungal growth. Transplant excess plants to other pots or other garden areas to provide good air circulation.

Conduct Regular Plant Inspection

Regularly inspect your plants, especially after rainy days. Look for signs of fungal infection, such as spots, smears, or discoloration. The moment you notice any of these signs, take immediate action to prevent the spread of the disease.

If there are a few leaves with the infection, remove them from the plant. Pruning diseased leaves can help to reduce the spread of disease. If a whole plant is infected, remove it from the rest of the plants and destroy it to prevent further spread.

Home Remedies for Fungal Infections on Plants

If all the preventive measures above will not stop fungal infection, here are some home remedies you can use to treat the infection.
