The best pre-emergent crabgrass killer, in my opinion is a liquid formulation. While there are several products available in the stores, they all contain a variety of chemicals and surfactants that attack the crabgrass plant at various stages of growth. The chemicals used in these applications are not considered “natural” chemicals and have been banned in some areas because of possible health risks. Liquid formulations, as well, can be easily stored at room temperature and sprayed on any desired area.
Not long ago, a friend asked me which was the best preemergent crabgrass killer. I immediately knew what he was getting at and so followed his lead. He then went out and got the best crabgrass killer he could find. What he got was a concoction of chemicals, surfactants and enzymes which were supposed to make the crabgrass plants stop growing. It was nothing more than a hodgepodge of ingredients which barely worked.
I suggested he try the best crabgrass killer he could find instead of trying anything that would work. I wasn’t surprised to learn that there were many weed killers out there with no apparent difference between them other than the fact that they all contained chemicals. I did a little research into these so that I would be aware of what I was buying. There is nothing worse than buying a herbicide only to find out it is not edible and can be harmful to pets. So I would rather suggest that people use a post-emergent and edible crabgrass killer in conjunction with each other.
There are two general-purpose weed killers on the market today. They are called Green Seal and Preventive Mixture (PMR). Both have the advantage of containing similar elements, but there are clear differences in how well they work. I would suggest using the best crabgrass killer you can find for general application.
A preemergent crabgrass herbicide acts quickly so you can finish the job in a reasonable amount of time. Plus you will save money since it costs more to purchase the preemergent herbicide than the post-emergent variety. You need to apply the pre-emergent crabgrass herbicide right after you see the crabgrass growing.
The best way to apply the crabgrass herbicide is to float it on the top of the soil where the crabgrass is growing. Then you just get rid of the weed from the roots by hand. You want to make sure you do not damage the crabgrass or kill it while trying to get rid of the weed.
It is important to know that crabgrass killers do not necessarily prevent crabgrass growth. Some crabgrass herbsicides only get rid of the weeds from the plant’s roots. Other crabgrass herbicides will kill the roots as well. The best way to keep crabgrass from growing back is to remove the weeds from the root system. This is why I prefer Chlorine Free Weed Killer over other crabgrass killers. There are other good weed killers on the market but they do not have the same effect as the chlorinated one does.
So now you know the two main ways to kill crabgrass and which is the best crabgrass killer. As with any insect you must learn how to control the problem before you kill it. But killing them kills them. The best crabgrass killer is a preventative measure. Keep your crabgrass killing powers at bay and your garden free of pesky little invasions.
If you have the time, hire a professional who has been dealing with crabgrass and weeds for years. But if you’re busy or have a small budget, learn how to use a crabgrass killer yourself. It’s easy to learn how to use it. Simply apply the weed killer to the crabgrass and watch the weeds die after just a few days.
Remember that crabgrass killers are not supposed to directly kill the crab grass. They are meant to indirectly cause the weed to wither and die. That is why you see a fine spray of the crabgrass killer on the crabgrass. The weed dies because it no longer has a source of nutrients and oxygen.
You can also create an airtight container to encourage the growth of crabgrass. Fill the container with enough water so there is no air. Set your crabgrass killer inside and let it do its work. Soon, you will start seeing the sprouts of crabgrass and weeds emerging from your container. Soon, you will have a beautiful lawn free from weeds.
