Why Remove Dandelions
Technically speaking, the Dandelion (Taraxacum officionale) is not a weed but a flowering plant with a heap of benefits. The whole plant is loaded with vitamins and antioxidants that could boost your health. However, despite the plant’s health benefits, they can become a nuisance when they grow on areas you don’t want them to.
Seeds easily get carried away by the wind and can propagate on the area where they land. Their taproot can grow up to 10 inches long, which can be quite difficult to uproot.
Different Methods of Killing Dandelions
There are two common ways in removing dandelions, either you pull it out manually or use an herbicide. The former may work, especially if there is only a few plants to remove. However, if you are going to remove an entire yard of dandelions, it will entail a tedious labor. This is where you will need herbicides. These products contain substances that were developed to inhibit the growth of dandelions and other similar weeds.
Herbicides penetrate the plant through the leaves then work all the way down to the roots to kill the whole plant. The good thing about these products is they don’t do any harm to the surrounding grass or plants for as long as you strictly follow the formulas in the instruction.
Different Types of Weed Killers
Before you make a random purchase of any weed killer available, it is important to know the different types of weed killers. The better your knowledge on the type to be used, the better you can determine what type will work for you. Weed killers can be classified according to the following types:
This kind of weed killer kills any weed it comes in contact with. The herbicide enters the plant’s system through the stomata of the leaf. Think of the stomata as the door of the plant that needs to be open for the infiltration to be successful. However, the stomata opens only during the time that its growth is active and photosynthesis is happening. Thus, the best time to use this type of weed killer during the plant’s growing season and early times of the day.
Most weed killers can be categorized as systemic, which means that the weed killer needs to access the plant’s internal transport system so it can kill it from the inside.
If you want to kill the weed and also render the soil unusable for many months up to a year, this will be of help. These weed killers contain a substance that could poison the soil around the plant. Once used, you will not be able to utilize that portion to grow any other plant or flower for months. This is because the substances will reside on the soil for quite a while, making it uninhabitable. Ideal applications for these weed killers would be areas outside the house where you do not want any plants to grow like driveways and paths.
As the name implies, these weed killers intentionally target a certain weed but preserves the surrounding plants or grass. When applied, the product will only affect plants with broad leaves like dandelions and daisies and having no effect on plants with narrow leaves.
Obviously, if selective types will target a certain weed, these types will not give any care to whatever it comes into contact with just like contact-type weed killers. The difference here is that they cause severe damage to any plants so you should be careful in using this product. Do not ever spray in windy weather as the solution might drift away into plants or flowers.
Factors to Consider in Applying Dandelion Killers
You may have the best dandelion killer in town, but if you are not fully aware of all important factors during application, your success might turn into failure, resulting into additional costs due to repurchasing.
This can greatly affect your application as the presence of water or rain will dilute the solution. The mix you have meticulously prepared will not be effective anymore. If moisture is very heavy, there is a high tendency for the solution to runoff, and your weed killer cannot enter the leaves of the plant successfully.
Applying during warm temperature works best for weed killers as it promotes better absorption. This will also help avoid droplets to be off-target during times of high moisture.
It is also imperative to assess the wind condition before applying your weed killer. High wind speed can interfere with your application and may cause some sprayed droplets to drift off from the targeted weed. The recommended wind speed is 3 to 7 MPH.
Nozzle type will control the droplet size which will depend on the type of weed you are dealing with. Also make sure that nozzles are clean and free from any dirt to avoid any blockages during application.
The mix will depend on what type of plant to be used and the size of the area. For dandelions, there is also a specific mix, so you need to carefully follow what is being stated in the guide.
It’s a close matchup of all weed killers as they all accomplish the goal of killing dandelions if properly executed. However, if we consider all the factors such as quickness of results and pricing, the clear winner would be the Ortho Weed B Gon Weed Killer. The product is highly recommended by most gardeners because of its excellent performance and its price point is still affordable.
Our runner-up would be Roundup For Lawns3 Ready-To-Spray since it still performs superbly while not selling at a very high price. Third goes to Ortho 9906010 Weed B Gon Plus Crabgrass Control Concentrate2. Although it is bit pricey, the high concentration is really a requisite for effective killing of dandelions.
The last two would go to the remaining two Spectracide and Eliminator Concentrates. Both are still valuable products, but their concentrations may not be comparable to the other three.
