Just like other vegetables from the cabbage family, broccoli (Brassica oleracea) is extremely prone to be affected by worms. This article is everything about, how to get rid of broccoli worms naturally?
After all, what can be more annoying than spending hours of your time and hard work growing your broccoli plant and taking care of it, only to find out that it has been affected by some nasty worms and pests? But don’t worry, you can save your hard work from going in vain. Timely treatment could help save your broccoli plants from deteriorating as a result of these pest attacks.
What are worms and pests? Are all kinds of worms harmful?
You might be wondering what are worms and how are they different from pests? Well, in simple words we can say that worms are invertebrate animals with elongated and slender bodies, but it is important to remember and understand that not all worms are pests!
Pests refer to those organisms that can cause potential harm and threat to your plants by infecting them and causing various diseases, While it is possible that the pest infesting your plant can be a worm but it is not necessary that all worms are pests!
Some worms, for example, the earthworm can actually prove to be extremely beneficial for your broccoli plants, and thus if you see earthworms in your garden then welcome them instead of trying to get rid of them.
Earthworms, by creating tiny little holes in the soil help to improve soil aeration and water drainage. And that is exactly what your broccoli plants need – soil with good water drainage.
Not only this, earthworms also help to break down the organic matter present in the soil into nutrients that can be used by your broccoli plant.
Some of the worms that can actually prove to be useful for your plant’s help include- earthworms, grub worms, millipedes, etc.
In fact, If you are growing your broccoli plant in a large garden bed, or a large area, then you can even add earthworms to the soil by yourself. You can easily purchase earthworms from garden supply stores.
However, it is important to note here that these worms feed on organic matter for example manure, leaves, grass, etc.
Thus, if you are growing your plant in a pot, then it is recommended not to add these worms as in such cases, these worms tend to feed on the roots of your plant. Thus even the good worms will be beneficial only if they have something to feed on.

Some of the healthy habits that you can follow for a healthy broccoli plant will be to ensure that your plant receives a minimum of 6 to 7 hours of sunlight daily.

B) Curative measures for broccoli worms
1. Hand-picking the worms
The first most common and hassle-free way to get rid of insects or pests from your broccoli plant would be to handpick them. You can use a pair of tweezers and remove these insects or pests manually. Of course, this process is only suitable when the pests are large enough and are clearly visible to the naked eye.
This method is more suitable if you have just started to notice pests in your broccoli plants. Hand-picking and removing these worms or insects on time will help prevent your broccoli plant from pest infestations and further diseases.
However, if you see a large number of these pests, then the handpicking method might not be a very convenient one and also could be extremely time-consuming and tiring.
2. Use neem leaves and neem oil to get rid of pests
Neem (Azadirachta indica) acts as an excellent repellent for pests and other harmful insects. Neem oil is effective against a wide variety of pests and insects such as caterpillars aphids, mites, millipedes, mealy bugs, leafhoppers, etc.
Thus, neem acts as an amazing natural insecticide and fungicide. To get rid of the pests in your broccoli plant or even to control pest attacks, you can spray some neem oil mixture around your broccoli plant.
You can take about 2 or 3 tablespoons of pure or essential neem oil and mix it in a gallon of water. Pour this mixture into a spray bottle and spray it over your broccoli plants. This works not only as a preventive measure but also is a great way for controlling pests in case your broccoli plant is infected by them.
Remember not to directly spray neem oil over your plants. Spraying pure neem oil directly over your broccoli plants can be too strong and harmful for your broccoli plant especially if it is very young.
Another point to note while using neem oil as an insecticide is that try to use this spray during the evening time or at a time when there is no harsh or strong sunlight because a combination of strong sunlight and neem oil spray can prove to be harmful to your plant.
Yet another way to use neem to get rid of worms and pests on your broccoli plant is to use neem leaves. For this, you need to take some neem leaves and boil them in water for some time.
Wait for this neem-infused water to cool down as spraying hot water over your plants could be harmful to them. Now, once it has cooled down, you can take this neem-infused water and pour it into a spray bottle and spray it over your broccoli plants.
This is a safe, completely natural, and yet a very effective way to control pest attacks or pest infestations on your broccoli plants.
