How to Control Black Root Rot

Black root rot is a fungus that is known to infect your plants, particularly pansies and vincas. It results in a large amount of plant loss, because it causes the roots to be unable to absorb nutrients. The plants eventually turn yellow and die. Follow these steps to learn how to control black root rot.

Difficulty: Moderate

Instructions

1. Be sanitary. Never reuse the plastic pots or trays in which you bought your plants.

2. Examine the roots of all plants that you purchase and are introducing in to the garden. Healthy roots should be white.

3. Minimize the stress in your garden as it increases the black root rot. Regulate the temperature. Minimize excess moisture, soluble salts and fungicides in your garden.

4. Plant the flowers immediately after purchase and inspection so they are not vulnerable to stress, increasing the likelihood of developing black root rot.

5. Utilize an acidic pH level of 5.5 to 5.8 at the first sign of black root rot to control it. This can reduce the further development of black root rot.

6. Remove all plants that are affected with black root rot immediately to prevent spreading it. The plants are unable to recover.

Tips & Warnings

• Make sure that your garden has proper drainage. You may need to use a raised bed in order to achieve proper drainage.
• Avoid planting your flowers on land where there was once a case of black root rot. The disease stays in the soil.
