How to Get Rid of Nematodes on Feverfew Plant

Updated: March 2, 2023

Feverfew is a popular herb that is commonly used for its medicinal properties. It is also known for its ability to repel insects, making it a great addition to any garden. However, one of the most common problems that people face when growing feverfew is nematodes. Nematodes are microscopic worms that can cause serious damage to the roots of the plant, leading to stunted growth and reduced yield. In this article, we will discuss how to get rid of nematodes on feverfew plants.

What are Nematodes?

Nematodes are tiny worms that live in soil and feed on the roots of plants. There are many different types of nematodes, but the ones that are most commonly found in gardens are root-knot nematodes. These nematodes cause the roots of the plant to become swollen and malformed, which can lead to stunted growth, yellowing leaves, and reduced yield.

Signs of Nematode Infestation

The first sign of nematode infestation is often stunted growth. The plant may also have yellowing leaves and wilting, even if it has been watered adequately. If you suspect that your feverfew plant has nematodes, you can dig up the root system and examine it for signs of damage. Infested roots will be swollen and may have small bumps or knots on them.

How to Get Rid of Nematodes on Feverfew Plant

There are several methods that you can use to get rid of nematodes on your feverfew plant. Here are some of the most effective methods:

Crop Rotation

One of the most effective ways to control nematodes is through crop rotation. This involves planting a different crop in the same location where your feverfew was last year. Nematodes are host-specific, which means that they can only survive on certain plants. By planting a different crop, you are depriving the nematodes of their food source, which will help to reduce their population.

Solarization

Solarization is a process that involves covering the soil with clear plastic and leaving it in place for several weeks during the hottest part of the summer. The heat from the sun will raise the temperature of the soil to a level that is lethal to nematodes. This method is most effective in areas with high temperatures and abundant sunlight.

Soil Amendments

There are several soil amendments that can help to control nematodes. One of the most effective is composted manure. This can be added to the soil before planting, or it can be used as a side dressing during the growing season. Other effective amendments include bone meal, rock phosphate, and blood meal.

Chemical Control

If other methods have failed, you may need to resort to chemical control. There are several nematicides (chemicals that kill nematodes) available on the market. These should be used with caution, as they can also harm beneficial organisms in the soil. Always follow the instructions carefully and wear protective clothing when using these products.

FAQ

Can I replant in the same location after removing an infested plant?

It is not recommended to replant in the same location for at least one year after removing an infested plant.

Can I use nematode-resistant varieties of feverfew?

Yes, there are some varieties of feverfew that are resistant to nematodes. Check with your local nursery or garden center for recommendations.

How often should I rotate my crops?

It is recommended to rotate crops every two to three years to prevent nematode buildup.

Conclusion

Nematodes can be a serious problem for feverfew growers, but there are several methods available for controlling them. Crop rotation, solarization, soil amendments, and chemical control are all effective methods for reducing nematode populations. By following these guidelines, you can ensure that your feverfew plants remain healthy and productive for years to come.
