How to Get Rid of Caterpillars on Freesia Plant

Freesia plants are beautiful with their colorful flowers and sweet fragrance. However, they are not immune to the harmful effects of caterpillars. Caterpillars can cause severe damage to your freesia plants, and if not controlled, they can quickly destroy your entire garden. Therefore, it’s important to learn how to get rid of caterpillars on freesia plants. This article will provide you with some tips on how to do that.

Identify the Caterpillars

Before you start implementing any control measures, it’s essential to identify the caterpillars that are feeding on your freesia plants. There are several types of caterpillars that can attack your freesia plants, including cutworms, loopers, and armyworms. Cutworms cut through the stem of the plant at ground level, while loopers and armyworms eat the leaves of the plant.

Handpicking

If you only have a few caterpillars on your freesia plants, you can handpick them off. Wear gloves and gently pluck off the caterpillars from the leaves or stem of the plant. Drop them into a bucket of soapy water to kill them.

Use Neem Oil

Neem oil is a natural insecticide that works against a wide range of pests, including caterpillars. It’s safe for humans, pets, and beneficial insects such as bees and butterflies. Mix one tablespoon of neem oil and one tablespoon of liquid soap in one gallon of water. Spray the solution on your freesia plants every two weeks until the infestation is under control.

Use Bacillus Thuringiensis (BT)

Bacillus thuringiensis (BT) is a bacterial insecticide that targets caterpillars. It’s safe for humans, pets, and beneficial insects such as bees and butterflies. Mix one teaspoon of BT powder in one gallon of water. Spray the solution on your freesia plants, making sure to cover both sides of the leaves. Repeat the application every five to seven days until the infestation is under control.

Use Insecticidal Soap

Insecticidal soap is a safe and effective way to control caterpillars on freesia plants. It works by suffocating the insects by clogging their breathing pores. Mix two tablespoons of insecticidal soap in one gallon of water. Spray the solution on your freesia plants, making sure to cover both sides of the leaves. Repeat the application every seven to ten days until the infestation is under control.

Companion Planting

Companion planting is an effective way to repel caterpillars naturally. Plant herbs such as basil, mint, and thyme around your freesia plants to repel caterpillars. You can also plant marigolds and nasturtiums, which are known to deter pests.

Maintain Good Garden Hygiene

One of the best ways to prevent caterpillar infestations in your garden is to maintain good garden hygiene. Remove fallen leaves and debris from around your freesia plants regularly. This will prevent caterpillars from using these as hiding places.
