How to Get Rid of Mold on Freesia Plant

Updated: July 3, 2022

Freesia plants are a popular choice among gardeners due to their fragrant and colorful blooms. However, they are also susceptible to mold growth, which can damage the plant’s health and appearance. Mold on freesia leaves can be caused by a variety of factors, including overwatering, poor air circulation, and high humidity levels. In this article, we will discuss how to get rid of mold on freesia plants and prevent it from coming back.

Step 1: Identify the Type of Mold

Before you start treating mold on your freesia plant, it’s important to identify the type of mold that’s growing on it. There are several types of mold that can affect freesia plants, including powdery mildew, black spot, and botrytis blight. Each type of mold requires a different treatment approach, so it’s essential to identify the type accurately.

  • Powdery Mildew: Powdery mildew appears as a white or grayish powdery substance on the leaves and stems of the plant. It thrives in warm and humid conditions.
  • Black Spot: Black spot appears as black spots on the leaves and stems of the plant. It is caused by excess moisture and poor air circulation.
  • Botrytis Blight: Botrytis blight appears as brown spots on the leaves and flowers of the plant. It thrives in wet conditions.

Step 2: Remove Infected Leaves

Once you have identified the type of mold affecting your freesia plant, you should remove any infected leaves immediately. This will prevent the mold from spreading to other parts of the plant and help keep it healthy. Use a pair of sharp scissors or pruning shears to cut off any infected leaves at their base. Be sure to clean your tools with rubbing alcohol or bleach after use to avoid spreading the mold to other plants.

Step 3: Improve Air Circulation

Mold thrives in damp, humid conditions, so it’s essential to improve air circulation around your freesia plant to prevent mold growth. You can do this by placing a fan near the plant or by moving it to a location with better airflow. If you have multiple freesia plants, avoid overcrowding them to allow for better air circulation.

Step 4: Reduce Humidity Levels

Reducing humidity levels is another effective way to prevent mold growth on freesia plants. You can do this by watering the plant less frequently and avoiding overhead watering. Instead, water the plant at its base and allow the soil to dry out between waterings. You can also use a dehumidifier or air conditioner to reduce humidity levels in your home or greenhouse.

Step 5: Apply Fungicides

If the mold on your freesia plant doesn’t go away with the above steps, you may need to apply a fungicide. There are several fungicides available that are safe for use on freesia plants, including copper-based and sulfur-based products. Be sure to follow the instructions carefully when applying fungicides and wear protective gear such as gloves and a mask.
