When it comes to animals that will eat kale, there are a few main culprits to watch out for in the garden. While slugs and snails are often blamed for damaging kale leaves, they are not typically the primary culprits. Instead, caterpillars, particularly cabbage worms and cabbage loopers, are the main pests that feed on kale plants.
Cabbage worms and cabbage loopers are the larvae of certain species of moths, such as the cabbage white butterfly. These insects lay their eggs on the undersides of kale leaves, and when the eggs hatch, the caterpillars begin to feed on the foliage. As they grow, they can cause significant damage by munching on the leaves, leaving behind unsightly holes.
I have personally experienced the frustration of finding holes in my kale leaves, only to discover cabbage worms as the culprits. These pests can quickly multiply and infest the entire kale patch if left unchecked. It is essential to be vigilant and take action as soon as you notice any signs of damage.
To identify cabbage worms and cabbage loopers, you can look for small green caterpillars with a slimy appearance. They often blend in with the foliage, making them challenging to spot initially. However, if you inspect the undersides of the leaves carefully, you should be able to find them.
To control caterpillar infestations and protect your kale plants, there are several strategies you can employ:
1. Hand-picking: This method involves physically removing the caterpillars from the plants by hand. While it may be time-consuming, it can be effective for small-scale infestations. Remember to wear gloves and dispose of the caterpillars away from your garden to prevent them from returning.
2. Biological control: Introducing natural predators of cabbage worms and cabbage loopers, such as parasitic wasps or birds, can help keep their population in check. Encouraging habitat diversity in your garden can attract these beneficial insects and birds.
3. Row covers: Covering your kale plants with a fine mesh or row cover can prevent adult butterflies from laying their eggs on the leaves. This method acts as a physical barrier and can effectively reduce caterpillar infestations.
4. Organic insecticides: If the infestation is severe, you may consider using organic insecticides specifically formulated for caterpillar control. These products contain naturally derived ingredients, such as Bacillus thuringiensis (Bt), which is toxic to caterpillars but safe for humans and other beneficial insects.
5. Crop rotation and sanitation: Practicing crop rotation can help break the life cycle of cabbage worms and cabbage loopers. By moving your kale plants to a different location each year, you reduce the likelihood of recurring infestations. Additionally, removing and destroying any infested plant debris can prevent pests from overwintering and reinfesting your garden in the following season.
It’s important to note that while caterpillars are the primary pests that feed on kale, other animals may occasionally nibble on the leaves as well. For example, rabbits, deer, and certain insects like aphids or flea beetles may cause damage to kale plants. However, these instances are relatively rare compared to caterpillar infestations.
When it comes to animals that eat kale, caterpillars, particularly cabbage worms and cabbage loopers, are the most likely culprits. Being proactive in monitoring and controlling these pests is crucial to ensure the health and productivity of your kale plants.
