How to Get Rid of Caterpillars on Weeping Jade Plant

Updated: July 15, 2023

Caterpillars are common pests that can wreak havoc on our beloved plants. One plant that is often targeted by these pesky critters is the weeping jade plant. The weeping jade plant (Crassula argentea) is a popular succulent known for its cascading branches and glossy, teardrop-shaped leaves. However, caterpillars can quickly turn this beautiful plant into a chewed-up mess. In this article, we will explore effective methods to get rid of caterpillars on your weeping jade plant and keep it healthy and thriving.

Identifying the Problem

Before you can effectively treat caterpillar infestation on your weeping jade plant, it’s important to identify the problem accurately. Caterpillars are the larval stage of moths and butterflies, and they can vary in appearance depending on the species. They typically have soft bodies, multiple pairs of legs, and feed on plant leaves.

When it comes to weeping jade plants, the most common caterpillar species that infests them is the cabbage looper (Trichoplusia ni). Cabbage loopers are green or brown in color, about an inch long, and can be easily identified by their looping movement when crawling. They chew irregular holes in the leaves and can cause severe damage if left untreated.

Natural Methods of Control

If you notice caterpillars on your weeping jade plant, you may want to try some natural methods of control before resorting to chemical pesticides. Here are a few effective ways to get rid of caterpillars using natural remedies:

1. Handpicking

One of the simplest ways to control caterpillars is by handpicking them off your weeping jade plant. Carefully inspect each leaf, stem, and branch for any signs of caterpillars or their eggs. Wear gloves if you’re squeamish, and drop the caterpillars into a bucket of soapy water to drown them. This method may be time-consuming, but it can be an effective way to control smaller infestations.

2. Neem Oil Spray

Neem oil is a natural insecticide derived from the neem tree. It has been used for centuries to control pests, including caterpillars, and is considered safe for most plants. To create a neem oil spray, mix 1-2 teaspoons of neem oil with a quart of water and a few drops of liquid soap. Spray the solution liberally on your weeping jade plant, making sure to cover all affected areas. Repeat the treatment every 7-10 days until the caterpillar infestation is under control.

3. Bacillus thuringiensis (Bt)

Bacillus thuringiensis, or Bt for short, is a naturally occurring soil bacterium that produces proteins toxic to many insect larvae, including caterpillars. Bt products are available in powder or liquid form and can be sprayed directly on your weeping jade plant. Follow the product instructions carefully for proper application, as different formulations may have varying concentrations of Bt. It’s important to note that Bt is specific to caterpillars and generally safe for beneficial insects, humans, and other animals.

Chemical Control Options

If natural methods don’t provide satisfactory results or the caterpillar infestation is severe, you may need to resort to chemical control options. However, it’s crucial to use pesticides responsibly and follow the instructions provided by the manufacturer. Here are two commonly used chemical pesticides for caterpillar control:

1. Spinosad

Spinosad is an insecticide derived from a naturally occurring soil bacterium. It is effective against a wide range of pests, including caterpillars, and has low toxicity to humans and animals. Spinosad products are available in various formulations, such as sprays, granules, and powders. Follow the product instructions for proper application and reapply as needed, usually every 7-14 days.

2. Pyrethrin

Pyrethrin is a natural insecticide derived from chrysanthemum flowers. It is commonly used to control a variety of pests, including caterpillars. Pyrethrin products are available in various forms, such as sprays and dusts. Always read and follow the label instructions carefully for proper application and safety precautions.

Preventing Future Infestations

After successfully getting rid of caterpillars on your weeping jade plant, it’s important to take preventive measures to avoid future infestations. Here are a few tips to keep your plant safe:

  1. Regularly inspect your weeping jade plant for signs of caterpillars or their eggs.
  2. Keep the area around your plant clean and free of debris, as caterpillars often hide in fallen leaves or plant debris.
  3. Avoid over-fertilizing your plant, as this can attract pests.
  4. If you notice caterpillars on nearby plants, take immediate action to prevent them from spreading to your weeping jade plant.
  5. Consider planting companion plants that naturally repel caterpillars, such as marigolds or dill.

By implementing these preventive measures and promptly addressing any caterpillar infestations, you can keep your weeping jade plant healthy and free from damage caused by these voracious pests.

In conclusion, caterpillars can pose a significant threat to the health and appearance of your weeping jade plant. However, by correctly identifying the problem and using natural or chemical control options, you can effectively get rid of caterpillars and protect your beloved plant. Remember to always follow the instructions provided by the manufacturer when using chemical pesticides and take preventive measures to avoid future infestations. With proper care and attention, your weeping jade plant will continue to thrive and bring beauty to your indoor or outdoor spaces.
