Gray mold in a hydroponic gardenGray mold, also known as Botrytis, is a fungus that affects many varieties of plants. It can affect any part of a plant. Gray mold spreads quickly and often results in the loss of the plant. It is a white to gray growth that eventually turns the affected area brown.

How Does Gray Mold Start?

Gray mold produces spores that are disbursed by water or through the air. To grow, the fungus needs a high humidity environment and nutrients to survive. It growth often starts and an area of the plant that was damaged. When a piece of a plant breaks, it exposes the nutrients the mold needs to start its growing. Once started, it spreads to other parts of the plant. In addition to damaged parts of a plant, you may also see gray mold form on seedlings in high humidity, dying flowers, and cuttings.

How To Get Rid Of Gray Mold

It is recommended to remove the infected plant entirely from the hydroponic garden to prevent the mold from spreading to other plants. If you were to cut off the molded area, you would expose more tissue for mold growth to occur again. When removing infected plants, dispose them far away from your hydroponic garden. Be careful not to damage any healthy plants in the process.
