What is eating my broccoli and cauliflower?

I’ve encountered this problem myself in my own garden, and I know how frustrating it can be to see your beautiful broccoli and cauliflower plants being attacked. There are a couple of common culprits that could be causing the damage.

First, let’s talk about cabbage aphids. These tiny insects may be called cabbage aphids, but don’t be fooled – they can also wreak havoc on your broccoli and cauliflower plants. These pests feed on the foliage of the plants, sucking out the sap and nutrients. This can lead to stunted growth, yellowing leaves, and overall weakened plants. Not only that, but cabbage aphids also secrete a sticky substance called honeydew, which can attract ants and other pests.

To get rid of cabbage aphids, you can try a few different methods. One option is to blast the plants with a strong stream of water to dislodge the aphids. You can also try using insecticidal soap or neem oil, which are both effective at controlling aphids. Another natural option is to introduce beneficial insects, such as ladybugs or lacewings, which will feed on the aphids and help to control their population.

Now, let’s move on to the cabbage maggot. These pests are actually the larvae of a small fly, and they can cause serious damage to the roots and underground stems of your broccoli and cauliflower plants. The symptoms of cabbage maggot infestation include wilting plants, stunted growth, and yellowing leaves. If you dig up the affected plants, you may even see the maggots themselves or their tunnels in the roots.

To prevent cabbage maggots, it’s important to practice good crop rotation. Avoid planting brassicas, such as broccoli and cauliflower, in the same area year after year. Instead, rotate your crops so that you’re not growing brassicas in the same spot more than once every three years. This can help to disrupt the life cycle of the cabbage maggots and reduce their numbers.

If you’re already dealing with a cabbage maggot infestation, you can try using floating row covers to physically block the flies from laying their eggs on your plants. Another option is to apply beneficial nematodes to the soil, which will attack and kill the maggots.

Cabbage aphids and cabbage maggots are two common pests that can wreak havoc on your broccoli and cauliflower plants. It’s important to identify the pests correctly and take action to control their populations. By using a combination of cultural practices, such as crop rotation and the use of beneficial insects or nematodes, you can protect your plants and keep them healthy.
