Zinnias are beautiful flowers that come in different colors, shapes, and sizes. They are easy to grow and maintain, making them a favorite among gardeners. However, caterpillars can be a menace to these plants as they can eat the leaves, buds, and flowers. In this article, we will discuss how you can get rid of caterpillars on your zinnia plant.
Before you start getting rid of caterpillars on your zinnia plant, it is essential to identify the type of caterpillar you are dealing with. Different caterpillars have different behaviors and characteristics. Some are harmless and can be left alone, while others can cause significant damage to your plants.
The most common caterpillars that attack zinnia plants are the cabbage worm, corn earworm, and cutworm. The cabbage worm is green and about an inch long, while the corn earworm is brown or green with stripes and can grow up to 1.5 inches long. The cutworm is a fat, shiny, black or gray caterpillar that curls into a circle when disturbed.
If you want to get rid of caterpillars on your zinnia plant without using chemicals, there are several natural remedies you can try. These remedies are safe for both the plant and the environment.
One of the easiest ways to get rid of caterpillars is by handpicking them off your zinnia plant. Wear gloves and inspect your plants daily to remove any visible caterpillars. Drop them into a pail filled with soapy water to kill them.
Neem oil is a natural pesticide that has been used for centuries to control pests. Mix two tablespoons of neem oil with one gallon of water in a spray bottle. Spray the mixture on the affected parts of your zinnia plant, including the leaves, buds, and flowers. This should help repel the caterpillars.
Garlic has natural pesticidal properties that can help deter caterpillars. Crush several cloves of garlic and mix them with water. Let the mixture sit overnight, then strain it into a spray bottle. Spray the mixture on your zinnia plant, making sure to cover all parts of the plant.
If natural remedies don’t work, you can use chemical pesticides to get rid of caterpillars on your zinnia plant. However, it is important to use these chemicals safely and responsibly.
Bt is a bacterial pesticide that can be used to control caterpillars. It is safe for humans, animals, and the environment. Mix one tablespoon of Bt with one gallon of water in a spray bottle. Spray the mixture on your zinnia plant, making sure to cover all parts of the plant.
Permethrin is a chemical pesticide that can be used to control caterpillars. It is toxic to bees and other beneficial insects, so use it with caution. Mix one tablespoon of permethrin with one gallon of water in a spray bottle. Spray the mixture on your zinnia plant, making sure to cover all parts of the plant.
