What to Consider Before Buying Dandelion Killers

When buying a dandelion killer, you deserve to buy only the best. For this to happen, you have to know what to look for. There are a lot of things that make a dandelion killer great for your lawn. The information below will help you choose the best dandelion killer for your lawn!

1. Organic vs inorganic/chemical

Dandelion herbicides are generally classified into two types, with each having its advantages and disadvantages. They include;

  1. Organic- It is environmentally friendly and safe for children and animals. However, they may take a bit longer to actually work and may also need more than one application.
  2. Inorganic/Chemical- Using a chemical weed killer to get rid of dandelions, has proven to be more effective and quick. However, they may be harmful to your children and animals.

2. Pre-emergent vs post-emergent

Once you have chosen between a chemical and an organic herbicide, then you have to choose between these two;

  1. Pre-emergent- These can attack the dandelion seeds before they germinate, thereby hindering the germinating process. However, they can't kill plants that are already growing.
  2. Post-emergent- They will kill the existing dandelion plants and control an extreme infestation. However, they can't stop the seeds from germinating and growing into new plants.

3. Durability

The best dandelion killers should have the ability to endure all kinds of weather. Some of them cannot be used when it rains or when it is too dry, therefore limiting the application time. Carefully read the instructions to know when you can or cannot use the product you are hoping to buy. If this information is unavailable, you can contact the seller or read the reviews to get this kind of information.

4. Effectiveness

A good weed killer should kill most, if not all different kinds of weeds. You will need to check if you can use it on the specific weeds that your lawn has. We recommend getting a multi-purpose killer that has stated whether the types of weeds it can be used on.

5. Selectivity

There are two types when it comes to selectivity

  1. Selective- With a selective herbicide, you can get rid of only the dandelions without damaging your lawn.
  2. Non-selective- Using a non-selective herbicide, means that any part that gets sprayed with also be killed.

6. Persistence

The persistence of either a selective or a non-selective herbicide shows how long it will remain active after the application. If the weed killer has a lasting effect and helps in stopping further growth, then it’s persistent. If it doesn't then it is non-persistent.

7. Liquid or Granular

Most dandelion killers are available in liquid form that is ready to spray with a hose. However, there are also granular or pellet herbicides. Granulated weed killers are easy to apply, although they are not safe if you have animals. This is because animals can easily consume these granules.

8. Price

Some herbicides for killing dandelions start at just over $10 while others may go up to $50. Ideally, you’ll need to have a budget. Most of the time, the price of the herbicides is dependent on the quantity of the concentrate such that; the higher its volume, the higher the price. However, this is not always the case.

9. Child And Pet Safety

Some chemical herbicides may be toxic to humans and animals. So, it is important to ensure that the product is safe and if not, ensure you take precautionary measures while applying it. Always read and follow the warning labels.

10. Dose Size

Apart from the price, this is another factor that determines the value of dandelion killers. The stronger and more concentrated the herbicide is, the more value for money it has. Highly potent herbicides mean that they achieve a lot with only a few tablespoons mixed in three to five gallons of water. Some less expensive killers may need half a liter to achieve the same results. Always check the dose size before buying a dandelion killer.
