Best Weed Killer For Lawns

The Weed Killer For Lawns Review

Weeds are every gardeners worst enemy. While a few here and there may not cause too much havoc on a flower bed (some say in small quantities it adds a little color contrast), when it comes to lawns there is absolutely no place for them whatsoever – problem being that lawns are excellent places for weeds to grow and spread alarmingly quickly. This makes it essential that the discerning gardener picks up a great quality weed killer – a task that is somewhat more difficult than many may have thought.

The main problem is that just like gardens, lawns tends to vary enormously and what works for one lawn in getting rid of pesky weeds may prove to be ineffective on others. Quite simply this is because weeds are different – and what works in eliminating one strain may be ineffective on others. Plus many lawns have more than one kind of lawn, and there is the risk that over-application of multiple weed killing agents can damage the grass and even the soil underneath.

So it’s essential that gardeners take the time to identify the strains of weeds that have emerged upon their lawns and purchase a quality weed killer that can stand up to the task. Here we’ll take a look at the best all-round weed killer to be found on the market, and also take the time to examine what gardeners need to be aware of when buying chemical agents to address the weed strains they have infesting their lawns.

Buyers Guide

There’s a wide range of weed killers to choose from and very often they will have a marketing niche claiming to have added prowess or particular benefits in a specific specialized field. Sometimes this can be very useful for those with very particular needs, but for the most part a quality weed killer suitable for lawn use needs to be able to perform the following at the very least in order to be worthy of consideration.

Do bear in mind that it’s always a sensible precaution to know as much about your lawn and the weeds that are present before making a purchase, as some weed killers can also damage certain strains of grass too.

1) Ideal Temperature For Application

Weed Killer For LawnsThis can be an issue for those living in very warm or especially colder states as many lawn weed killers require it to be applied at a certain temperature. In most cases this is ‘warm’ namely the standard spring and autumnal weather between which weeds tend to do most of their growing, so look for a typical optimum temperature of around 85 degrees for maximum efficiency.

2) Look For ‘Step-by-Step’ Products

It can often seem with lawn weed killers that manufacturers are a little coy about how to use their products for maximum efficiency. To a degree this is understandable – after all there’s a huge number of variables that can affect suitable application – but the best products will explain not just how to dilute the agent and spread it, but actually take time to explain the entire process.

There’s more to killing lawn weeds than simply spraying the agent – lawns need to be mowed often a few days in advance of application, temperatures need to be suitable and perhaps most important of all (and often most overlooked) is that application must be carried out during dry conditions! It’s really surprising how many lawn weed killers – even established names – are hazy on this information.

As a related side note to this – these products are one of the few were small print and details really can be useful, especially if your lawn has an uncommon kind of grass or you are addressing a particular species of weed. Take time to read it if you can, even better check out the manufacturer’s website and/or anecdotal feedback from other users.

3) Check Frequency Of Application

This can be very important as some products may require more frequent application than others. This can be because they simply aren’t very effective, or because they are more ‘holistic’ products offering a softer and more gentle treatment to the lawn.

The truth is that lawn weed killer really shouldn’t be needed to be applied more than twice per year, and that any more often than this can cause residual damage to the soil. The best products will suggest an application in early spring (temperature/conditions providing) and a second treatment early autumn in preparation for the cooler months.

There’s plenty to consider when buying a lawn weed killer but as mentioned above by far and away the most useful advice is to know your lawn and be certain to look for products that are suitable for use upon it. If using a weed killing product for the first time it can be sensible to make a small application to one section first of all in order to assess the results before completing an entire service.
