Best Weed killer Buyer’s Guide
After reading products reviews, you have probably 2-3 products that excite you. And the buying guide helps you narrow down the choice for the best weed killers.
What are The Things to Consider When Purchasing the Best Weed Killer?
1. Type of Weeds You Want to Eliminate
This will help determine which weed killer is right for you. If you have an infestation of grassy weeds, then a herbicide with broad-spectrum activity is probably going to be more effective than if you were trying to eliminate just one specific species of weed. For example, a product that kills Japanese beetles would not work well against dandelion because it does not target insects.
2. Choose Between Liquid Vs Granular Weed Killer
Liquid weed killers are generally safer to use around children and pets, but they may take longer to kill weeds. Granules tend to be faster acting, but they are usually more expensive.
3. Find a Low Toxicity Product
Many weed killers contain toxic ingredients such as glyphosate (Roundup), so make sure that you find a product that has been tested for safety and doesn’t contain any dangerous substances.
4. Your Budget
There are plenty of cheap weed killers out there, but they won’t do anything at all. Your best bet is to buy something that’s reasonably priced and works well.
5. How to Apply
Most weed killers require mixing with water and applying with a sprayer. Be careful about using too much weed killer, especially if you’re dealing with large areas of plants. Don’t assume that you’ve bought the perfect weed killer just because it worked well in the store. Always test the product before using it on your plants.
6. Keep Track of the Results
Once you start seeing weeds growing back after you’ve applied your weed killer, you’ll know that you need to reapply.
7. Use the Product Correctly
Read the instructions carefully and follow them exactly. Some weed killers only work on certain parts of the plant, so don’t expect to kill everything with one application.
Even though you might think that your weed killer is working perfectly, it could still be wearing off over time. As long as weeds are showing up again, you should keep reapplying until you see no growth.
