Using Weed Killer on Lawn Weeds Even Before They Sprout
Your regular weed killer does away with lawn weeds once they show up. That isn’t the most efficient way to get rid of weeds though. The best way to go about weeds is to put paid to them before they even show up. But there is more to using pre-emergent weedicide (which is what it is called) than just spraying it all over your garden. Let’s take a closer look at how you can take care of your weeds (not weed) even before they show up.
Weeds take over a lawn by spreading their buy 420 uk seeds around. Pre-emergent weed killer works by making sure that the seeds of lawn weeds don’t ever sprout. As the weed seeds lie in your soil through the winter months waiting for the temperature to be right again, come spring, you have a pretty great window of time in which to attack them. Applying pre-emergent weed killer at this time takes away the ability of the seeds to germinate. You can apply a weed seed killer in one of two ways. You can either use a liquid topical treatment or you could use emergent weed killer that comes pre-mixed with fertilizer. To do a good job here, you need to read your instructions carefully and follow them.
To apply pre-emergent weedicide correctly, you need to pick the right time. Using it too early can render it useless by not giving the weed seeds enough time to break down, and applying it too late can cause the weed seeds to sprout before any damage is done to them. The best time usually is around May, when spring is just starting out. That’s about the time when the soil is about 60 degrees – just the right temperature to kill lawn weeds in.
If sticking a thermometer in the soil seems like too much work, perhaps pre-emergent weed killer isn’t for you. You could easily get the timing wrong. Remember, this is a product that kills seeds. If you plan to be seeding your lawn with grass seeds, it will kill those too. For the best results, you should probably buy premixed weed killer and use it through a sprayer. If you buy the kind that you mix yourself, it can be a lot of needless hassle, and of course, you could get the proportion all wrong. And remember, weedicide is poison. You need to follow all instructions completely.
