Key Information About The Best Weed Killers
Pre-emergent vs. post-emergent weed controllers
As you were reading about weed killers, you saw the terms pre-emergent and post-emergent several times. Let’s clarify these terms.
- Pre-emergent Weed Control stops weeds from growing. This works by poisoning the seed so that it’s unable to germinate. So, when the seeds fall to the ground and come in contact with the pre-emergent weed control, they become unviable seeds. Thus, the growth of new weeds is thwarted.
- Post-emergent Weed Control kills existing weeds in your lawn or garden. The active ingredient in the weed spray is absorbed by the plant, poisoning it down to the roots. This process can take from hours to weeks depending on the type of weed.
Both ways will control weeds. Many gardeners and homeowners feel that the best weed control is a combination approach.
Important Weed Killer Label Information
Before you use any weed killer on the market, read the label carefully.
When weed killers are safe to use on your lawn, the label will indicate this or say “selective.” It will also give you a list of plant species it will kill, so you want to ensure you don’t accidentally kill your prized garden plants.
On the other hand, labels that state “non-selective” are also referred to as vegetation killers. This means, as the name implies, that they will kill any plant they come into contact with. Use care and caution!
Finally, read carefully to learn how to apply your weed killer. Some require a certain ratio of water be mixed in a sprayer, others are pre-mixed and in a spray dispenser. Knowing the correct mixing ratio, use, and spraying pressure is necessary for success.
Every homeowner has different needs. Whether you are trying to transform your lawn into a resort-esque feeling or clear a lot for new construction, you must choose the best weed killer according to those needs. The most effective weed killer, after all, is the one that does the best job for you.
