Buying Guide for Weed Killer
Before you pick a weed killer to get rid of unwanted guests in your lawn, take a look at some important information to help you make the best decision.
When you pick a concentrated herbicide, you need to mix it with water first. This means even a small bottle can cover the vast majority of your yard. The larger your yard, the more weed killer you will need. Make sure to read the label before spraying to find the right dilution for the weed killer.
Types of Weed Killer
Weed killers come in a variety of types to kill different plants. Many, like the options on this list, will kill a variety of weeds. Moreover, some weed killers kill both grass and weeds, which you will want if you are trying to kill any plan in pavers, flower beds, or other areas that aren’t your lawn. Instead, you may want a grass safe weed killer instead of the lawn.
Moreover, weed killers can be selective or non-selective. The latter will kill any plant you spray it on while a selective only works on specific plants without killing everything. You can also pick a systemic weed killer to reduce even the roots to dust, while a topical will only kill the top of the plan. Finally, some weed killers are persistent and will stay active to kill even future weed invasions while non-persistent works one time.
Different Types of Weeds
Every location contains different weeds, and not all weed killers work for every kind of lawn. Make sure to check the local weeds and what chemicals kill those specific intruders. Also, check local weather and season as some weed killers only work in dry climates while others will work during rain. Also, if you have a specific plant you want to kill, and it’s resistant to standard broad coverage weed killer, then you may need a specific killer for that weed.
Questions About Weed Killers
How do I apply weed killer?
First things first, make sure to see if your weed killer needs to be diluted. Make sure it’s not going to rain soon, even if some of the weed killers will work right before the storm. From there, follow a systematic pattern to cover your entire lawn without repeating. Apply an even layer across all of the weeds and then wait for the weeds to meet an untimely death.
Will weed killers harm my dog?
Yes, weed killers are herbicides that can kill plants and potentially harm both animals and humans. Check the bottle of your weed killer for instructions on how long before your pets or children can go back out into the yard to prevent issues.
While herbicides’ results may not be immediate, they can cause long-term problems and even lead to cancer. If possible, take your dog for a walk to relieve themselves instead of sending them to the backyard after spraying. Wait a full day if you can before sending your dog back out into a yard filled with weed killer.
Is it possible to be allergic to weed killer?
Yes, it is possible to be allergic to weed killer. Some people experience severe symptoms such as massive swelling, breathing issues, nausea, weakness, dizziness, and more. Even if you don’t have an allergy, it might be smart to wear a mask and eye cover to prevent unnecessary exposure and prevent a possible reaction. Also, you can use organic or natural options to avoid allergies if you know you have a sensitivity as they are safer and vinegar-based.
