How to Get Rid of Black Vine Weevils

Want to know how to get rid of black vine weevils? You’re not alone! Many gardeners deal with these critters that feed on ornamental plants. Contrary to popular belief, black vine weevils (also known as the taxus weevil) are most destructive in its larval stage.

Have you ever seen black vine weevil larvae? These small, white grubs are shaped like the letter “C” and they’re notorious for making tunnels through your plant’s root system when they’re feeding.

You’ll know that these creatures found their way to your plant because the leaves become dry even if you water them on a regular basis. What’s more, the plant’s growth becomes stunted.

On the other hand, adult black vine weevils are approximately 3/4-inch long and they’re large black insects that cannot fly. They have short, broad snouts, elbowed antennae, and short hairs all over their wings.

They commonly feed at night; they chew on the edges of leaves, causing plant damage. During the daytime, they hide between soil cracks and mulch, so they’re really hard to spot.

The Life Cycle of Black Vine Weevils

Black vine weevil larva can overwinter in the soil around the root structure of host plants. During the spring, they change to pupae and start emerging as adults. After 14 days or more (depending on temperature and condition), they begin depositing eggs near the crowns of the host plants. Hatching then occurs within 10 days, and the tiny larvae lair into the soil and begin feeding.


How to Control Black Vine Weevils

You can prevent the weevils from further damaging your plants by removing the mulch and other hiding areas around your plant’s base. Additionally, you should only water when necessary since larvae and adult black vine weevils prefer moist environments.

As Black Vine Weevils are non-flying insects, so they travel from plant to plant by crawling. You can prevent them from spreading to other plants by creating a sticky barrier as the first line of defense.

Apply diatomaceous earth for long-lasting pest protection. It is made up of small and tiny fossilized aquatic organisms, and it can kill weevils by damaging their outer layer as it crawls over the fine powder. Contains non-toxic ingredients that are good for your plants.

During the immature stages of its life cycle, the black vine weevil can be easily attacked by plant-friendly, small and slender worms called nematodes. The attack of the nematodes against the weevils usually takes place when the weevils infest potted plants.

If you’re planning to use a biological insecticide, you need to pick one that has an entomopathogenic fungus in it called Beauveria bassiana. This fungus can eliminate a wide range of pests and prevent reinfestation. Compared to other types of pesticides, this can effectively provide your plants with the protection they need.

Fast-acting crack and fissure sprays can be used around windows, doors, and vents to prevent adult weevils from possibly entering your home.



Weevil Removal Alternatives

If you are not a fan of using chemicals to kill these bugs, there are several natural alternatives you can try. For instance, you can always choose to make use of cloves, as well as bay leaves because weevils wouldn’t want to have anything to do with them.

White vinegar is also known to kill some other kind of weevils. After cleaning your containers with soapy water, wipe them down with white vinegar to prevent a future infestation from occurring.

Removal of weevils is an extensive process, but it’s definitely doable. For example, if you plan on storing dried goods, be sure to freeze them before you place them in containers that are properly sealed. Unless you do so, you’ll be running the risk of having the weevils back again.

If your kitchen was infested with weevils, give a team of pest experts a call right away. They may have experience in using eco-friendly solutions to kill weevils and protect your family from future infestation.

Put burlap fabric on the bases of trees and shrubs to trap weevils that hid under it during the day. As this type of pest cannot fly, checking your window, door, and ventilation edges will help you to mitigate this pest before an overt infestation.


Why Grow Your Plants Inside a Mini Greenhouse?

Have you ever used a mini greenhouse before? If you haven’t, it’s definitely worth a try. Here are some of the reasons why you should try using a mini greenhouse for your plants:


Protect your plants from pests and diseases

Gardeners use a mini greenhouse to protect their plants from pests and diseases. Aphids, black vine weevils, cabbage worms, and other pests can harm your plants. Keeping them in an enclosed space reduces the chances of diseases from spreading and pest infestation.


Keep them safe from bad weather

Heavy rain, excessive heat, storms, and overall bad weather can be damaging to your plants. Growing them inside a greenhouse shields them safe from inclement weather. Your plants will continue to grow healthily inside the greenhouse.


Final Thoughts on How to Get Rid Of Black Vine Weevils

There are many kinds of Weevils and they have different ways of damaging plants. Some weevils may directly eat the leaves while others use these plants to hatch their eggs and then the larvae then will eventually damage your plants.

It’s important to know how to get rid of black vine weevils to ensure that all your plants are healthy and pest-free.

How To Prevent Root Rot In Hydroponics: 3 Useful Tips

If you’re a newbie gardener who’s looking to find ways to hone your skills, you’d want to learn how to prevent root rot in hydroponics even before this problem affects your plants.

Hydroponics can be advantageous to crops in more ways than one. However, it also comes with risks of diseases, such as root rot, which can be destructive or even lethal to your plants.

Unfortunately, there are no effective methods to recover the wilted parts that were affected by the root rot once it hits your plants. The only thing you can do if you do not want this catastrophe to befall your crops is to prevent it before it happens. Read on to learn more about this subject.


What is Root Rot?

Root rot is a disease that attacks the plant roots and causes them to suffer decay. This usually happens when a lack of oxygen supply occurs in the substrate.

To give you an idea, think about plant roots that are submerged in water that only has a little oxygen in it. Over time, the plant suffocates and dies.

Aside from rot and decay, this disease also leads to the proliferation of fungi that are naturally present in the soil. These include Rhizoctonia, Alternaria, Pythium, Botrytis, Fusarium, or Phytophthora. As soon as fungi colonies start to grow, they tend to target the weakened roots and infect your precious plant babies.

Once the plant becomes infected, they won’t be able to take in what they need to grow – water, oxygen, and other nutrients. When this happens, it won’t be long before the plant dies.


What is Hydroponics?

In case you’re not aware, the term hydroponic is derived from a Latin word that means “working water”. To put it simply, hydroponics is an art that involves growing various types of plants without soil. If you’re like most people, the first thing that comes to mind when somebody talks about hydroponics would be a picture of plants with roots suspended into the water without using any type of growing medium.


Avoiding Root Rot in Hydroponic Systems

Detecting and identifying root rot can be tricky. When your plants get infected, their leaves and roots gradually wither until the whole crop itself dies from the lack of nutrients, which is a common symptom of many diseases.


What causes root rot in hydroponics?

One of the requirements in hydroponics systems is oxygen. Without it, your plants are basically on the road to death. On the other hand, lack of such is one of the major triggers for root rot, and it must be avoided at all costs.

Just like when planting in soil, you loosen up the ground so that your plants’ roots can have their required intake of oxygen. That is the case for crops grown in aqueous solutions as well. If they cannot breathe, they would not be able to grow.

Another agent for root rot is the temperature. The last thing you would want in your system are parasites that leech nutrients intended for your plants and infect the water during the process. In common terms, these fungi are called molds.

One of the best breeding grounds for these is warm and moist areas. For this reason, if the water temperature inside your reservoir is high, then you are susceptible to it. Something as minor as letting the solutions exposed to sunlight can already be a risk factor.


3 Useful Tips on How to prevent root rot in hydroponics

There is good news! Root rot in hydroponics can be prevented! Just follow these tips:

Tip#1: Use the right air pump

If you do not want root rot to affect your plants, you merely have to avoid its causes. If you need oxygen, keep the water bubbling by providing an air pump of appropriate size, and also give importance to proper ventilation in the room.


Tip #2: Maintain the temperature

The temperature should be maintained within the 70 to 80 degrees F range. Get rid of any materials that can make your system vulnerable to infections, and make sure not to disturb your crops while they are trying to grow.


Tip #3: Get rid of the rotten parts

However, if you failed in preventing the disease, then the rotten parts should be removed immediately. Cut them off as there is no chance of reviving them, and focus on the potential new growth instead. Fix your hydroponics system and eliminate the risks.


Why Give Greenhouse Gardening a Try?

Greenhouse gardening offers numerous benefits to greens aficionados who dare to take their gardening experience to the next level. Aside from acting as a shield against the effects of inclement weather, a mini, hobby, or semi-pro greenhouse can also serve as a protective layer that keeps harmful bugs and critters at bay.

What’s more, its enclosed structure allows you to control your plants’ growing conditions including the temperature, light, moisture, and ventilation of the greenhouse’s internal environment. With a controlled environment, you’ll be able to extend growing seasons and grow plants that aren’t native to your area.



No matter how well-informed you are about how to prevent root rot in hydroponics, you cannot completely eradicate the risks. Therefore, to avoid the worst-case scenario, you should be prepared to sacrifice the infected for the sake of others. While you’re at it, consider trying your hand at greenhouse gardening as well.
