Granular Vs Liquid Weed Killer 

There are typically two choices when it comes to destroying weeds – you can go for a liquid treatment or opt for a granular remedy. 

Liquid weed killer consists of herbicide and water. The mixture is applied to the area to decimate weeds. Application can be made via a simple pump, a spreader (such as the Spear & Jackson Pump Action Pressure Sprayer detailed above), or a high-tech, calibrated machine. The key to success lies in applying the right amount of liquid – too much can damage the grass and too little could prove ineffective. 

Granular weed killer is dry – small pellets overlaid with herbicide. The pellets can be applied to the area via spreaders, such as those mentioned previously the EverGreen Easy Spreader Plus and the EverGreen Handy Spreader. The granular weed killer can effectively control pesky weeds such as clover and buttercups. 

So, let’s see which comes of best as we compare the two:

Preparation:

Liquid weed killer has to be mixed correctly – you will need to measure the weed killer carefully and mix with water prior to use. Granular weed killer is easier to use in the sense you just pop the pellets in the spreader and you’re good to go. 

Application: 

Both liquid and granular are similar in terms of application. As with all strong chemicals you need to follow instructions and take care. The key to successful use of both depends on using the right amount to treat the area. 

Results: 

Both liquid and granular weed killer can prove to be effective in the fight against weeds. Granular weed killer works better when applied to wet weeds (as it ideally needs a moist surface to stick to). Liquid weed killer can be used on both wet and dry leaves. 

So, Which Is the Best Weed Killer for Lawns? 

Granular and liquid weed killers share similar qualities, both can control pesky weeds – leaving your garden looking lush and inviting. Of the five brands we have explored today it’s difficult to choose a clear winner. 

We like the fact that the Miracle-Gro Evergreen Complete 4in1 can guard against heat and drought whilst helping your grass to soak up vital nutrients. We’re also a fan of Elixir Gardens Complete Lawn – Weed, Feed and Moss Killer / Lawn Green Up which is deemed as easy to spread and effective.

There’s also Weedol 1 litre Lawn Weed Killer Concentrate Liquid, manufactured by a reputable company and professing to make a  noticeable difference to your lawn after just one treatment. We should also consider Resolva lawn Weed Killer, which can be used to treat nettles, ragwort, thistles and docks, along with daisies etc.

Finally, we must give a mention to Westland SafeLawn Natural Lawn Feed, a formula designed to be safely used and offering peace of mind if you have kids or pets. 

All have their merits, so we suggest you choose the best weed killers for lawns depending on your budget and your preference for granular or liquid weed killer. Don’t forget to invest in a spreader to make the job easier.
