Crossandra plants are beautiful and vibrant, with their bright orange or yellow flowers that can add a pop of color to any garden or indoor space. However, these plants are also susceptible to worm infestations, which can cause significant damage if not addressed promptly. In this article, we will discuss how to get rid of worms in crossandra plants.

Identify the Worms

The first step in getting rid of worms in your crossandra plant is identifying the type of worms you are dealing with. There are several types of worms that can infest crossandra plants, including:

  • Cutworms: These are caterpillars that are usually brown or black and are about an inch long. They live in the soil and feed on young seedlings and plant stems.
  • Armyworms: These are green, brown, or black caterpillars that live in the soil and feed on plant leaves.
  • Loopers: These are green caterpillars that move by “looping” their bodies. They feed on plant leaves and can cause significant damage.

Once you have identified the type of worm infesting your crossandra plant, you can take steps to eliminate them.

Natural Remedies

If you prefer natural remedies to chemical ones, there are several options for getting rid of worms in your crossandra plant:

  • Handpicking: If you only have a few worms on your plant, you can simply pick them off by hand and dispose of them.
  • Neem Oil: Neem oil is a natural insecticide that can be effective against a wide range of pests, including worms. Mix one tablespoon of neem oil with one liter of water and spray it onto your plant. Repeat every two weeks until the infestation is gone.
  • Diatomaceous Earth: Diatomaceous earth is a powdery substance made from the fossilized remains of marine phytoplankton. It is abrasive to insects and can kill them by dehydrating them. Sprinkle diatomaceous earth around the base of your plant and on the leaves, being careful not to inhale it.

Chemical Remedies

If natural remedies are not effective, you may need to use chemical pesticides. Here are some options:

  • Bacillus thuringiensis (Bt): Bt is a bacterium that is toxic to many types of worms. It is available in liquid or powder form and can be applied to your plant with a sprayer.
  • Spinosad: Spinosad is a natural insecticide that is effective against many types of worms. It is available in liquid or powder form and can be applied to your plant with a sprayer.
  • Carbaryl: Carbaryl is a chemical insecticide that is effective against many types of worms. It comes in liquid or powder form and can be applied to your plant with a sprayer.

When using chemical pesticides, it is important to follow the instructions carefully and wear protective clothing, such as gloves and a mask.

Prevention

Preventing worm infestations in your crossandra plant is the best way to avoid having to deal with them in the first place. Here are some tips for preventing worm infestations:

  • Keep Your Plant Healthy: A healthy plant is less susceptible to pests and diseases. Make sure your crossandra plant gets enough water, sunlight, and nutrients.
  • Clean Up Debris: Worms like to hide in debris, such as fallen leaves and dead flowers. Keep your plant area clean and free of debris.
  • Rotate Your Plants: If you have had a worm infestation in the past, rotate your crossandra plant with other plants every year to prevent the worms from building up in the soil.
  • Use Companion Planting: Some plants, such as marigolds and lavender, can repel worms. Plant them near your crossandra plant to deter worms.
