How to Get Rid of Nematodes on Watch Chain Plant

The watch chain plant, also known as Crassula lycopodioides, is a beautiful succulent that is native to South Africa. It gets its name from its unique trailing stems that resemble a watch chain. While this plant is relatively easy to care for, it can be susceptible to nematode infestations. Nematodes are microscopic roundworms that can cause damage to the roots of plants, leading to stunted growth and even death. If you notice signs of nematode infestation on your watch chain plant, it is important to take action promptly to save your plant. In this article, we will discuss how to get rid of nematodes on your watch chain plant.

Identifying Nematode Infestation

Before we dive into the methods of getting rid of nematodes, it is essential to be able to identify if your watch chain plant is indeed infested. Some common signs of nematode infestations include stunted growth, yellowing or wilting leaves, and the presence of galls or knots on the roots. If you notice any of these symptoms, it is likely that your plant has nematodes.

Quarantine and Isolation

The first step in dealing with a nematode infestation is to quarantine the affected plant and isolate it from other healthy plants. This will help prevent the spread of nematodes to other plants in your collection. Place the infested watch chain plant in a separate area away from other plants until you have successfully treated it.

Soil Solarization

Soil solarization is a natural method that utilizes the sun’s heat to kill pests and pathogens in the soil. To solarize the soil, start by removing any weeds or debris from the affected area. Water the soil thoroughly and cover it with a clear plastic sheet, ensuring that it is tightly sealed to trap the heat. Leave the plastic sheet in place for about 4-6 weeks during the hottest months of the year. The heat trapped under the plastic will kill nematodes and other pests in the soil. After the solarization period, remove the plastic and allow the soil to cool before replanting your watch chain plant.

Nematode-Resistant Plants

One effective way to prevent nematode infestations is by planting nematode-resistant plants alongside your watch chain plant. Some plants, such as marigolds, are known to repel nematodes and can act as a natural deterrent. By interplanting these resistant plants with your watch chain plant, you can help reduce the risk of nematode infestation. Additionally, rotating your crops regularly can also help disrupt the nematode life cycle and prevent their buildup in the soil.

Biological Control

Introducing beneficial organisms into the soil can help control nematode populations naturally. One example of a beneficial organism is the predatory nematode, Steinernema feltiae, which feeds on plant-parasitic nematodes. These predatory nematodes can be purchased from garden centers or online suppliers. Simply follow the instructions provided with the product to apply them to the affected area. Another option is to introduce beneficial fungi, such as Paecilomyces lilacinus, which can parasitize and kill nematodes.

Organic Soil Amendments

Certain organic soil amendments have been found to suppress nematode populations. Adding composted organic matter, such as well-rotted manure or compost, to the soil can improve its structure and fertility while also creating an environment less favorable for nematodes. Additionally, incorporating neem cake or meal into the soil can have a detrimental effect on nematodes due to its natural pesticidal properties.

Chemical Control

If all else fails, chemical control may be necessary to eradicate severe nematode infestations. However, it is important to note that chemical control should be the last resort and should be used with caution. Nematicides, such as fenamiphos or oxamyl, are available for commercial use and can effectively kill nematodes. It is crucial to carefully read and follow the instructions provided on the product labels to ensure safe and effective application.

Prevention is Key

Preventing nematode infestations is always better than dealing with them after they occur. Proper plant care practices, such as regular watering, fertilizing, and maintaining a healthy soil pH, can help keep your watch chain plant strong and less susceptible to nematodes. Avoid overwatering your plant, as excessive moisture can create favorable conditions for nematode growth. Additionally, practicing good hygiene by disinfecting gardening tools and containers can help prevent the transfer of nematodes between plants.

In conclusion, nematode infestations can be detrimental to your watch chain plant’s health. By identifying the signs early on and taking prompt action, you can save your plant from further damage. Remember to quarantine and isolate the affected plant, try natural methods like soil solarization, interplant with nematode-resistant plants, introduce beneficial organisms, use organic soil amendments, and only resort to chemical control as a last resort. With proper care and preventive measures, you can keep your watch chain plant thriving and free from nematode infestations.
