How to control horsehair worms in your greenhouse

Keep Your Greenhouse Worm-Free: Tips for Controlling Horsehair Worms

Horsehair worms, also known as Gordian worms, are parasitic worms that can infest your greenhouse and cause damage to your plants. These worms are long, thin, and resemble strands of hair. They are typically found in standing water or damp soil, which makes greenhouses an ideal environment for them to thrive. If you are dealing with a horsehair worm infestation in your greenhouse, here are some steps you can take to control them:

1. Identify the problem: The first step in controlling horsehair worms in your greenhouse is to identify the problem. Look for signs of infestation, such as worms in standing water or damp soil, or damage to your plants. Horsehair worms are typically found in the soil, so be sure to inspect the soil around your plants.

2. Remove standing water: Horsehair worms require standing water to survive, so removing any standing water in your greenhouse is an important step in controlling them. Check for any leaks or areas where water may be pooling, and fix these issues as soon as possible.

3. Improve drainage: Improving the drainage in your greenhouse can help prevent horsehair worms from infesting your plants. Make sure your greenhouse has proper drainage systems in place, such as gutters and downspouts, and ensure that the soil around your plants is well-drained.

4. Use nematodes: Nematodes are microscopic worms that feed on horsehair worms and other pests. You can purchase nematodes at your local garden center or online. Simply mix the nematodes with water and apply them to the soil around your plants.

5. Use insecticidal soap: Insecticidal soap can also be effective in controlling horsehair worms in your greenhouse. Apply the soap to the soil around your plants, following the instructions on the label.

6. Practice good plant hygiene: Finally, practicing good plant hygiene can help prevent horsehair worm infestations in your greenhouse. This includes regularly removing dead plant material, keeping the greenhouse clean and free of debris, and avoiding overwatering your plants.

By following these steps, you can effectively control horsehair worms in your greenhouse and protect your plants from damage. Remember to be patient and persistent in your efforts, as it may take some time to completely eliminate the infestation.
