Weeds are parasitic, which can damage your lawn’s beautiful landscape. It affects the valuable plantation in your garden as they compete with them for vital resources like water, light, and nutrition. Similarly, they can also inhabit hard surfaces like patios, driveways, or gravel-based areas. It happens when there’s even a slight crack in the hardscape. Besides its unsightly appearance, the unstoppable growth of weed roots can break up these surfaces.

Weeds are unrequired; hence you must kill them as soon as you see a single sign of their inhabitation. For this purpose, a strong weed killer works the best. Therefore, to simplify your hunt, we have searched and reviewed the 7 best weed killers of 2022. Using them will kill the current weed growth and prevent its relapse for several months.

Let’s get started.

Features of a Good Weed Killer

Besides being potent against weed growth, there are multiple things that a good weed killer should cover. Let’s briefly overview them.

Effectiveness

As discussed above, the first thing that matters the most is a weed killer’s efficacy level. A high-quality herbicide shouldn’t only kill the existing weeds but also prevent their re-growth for at least a few months.

Ingredients

A good weed killer must contain some potent ingredients to do the weed-killing job properly. Glyphosate or imazapyr are the top two choices in this case. Both are extremely powerful against stubborn weed growth.

Safety

Using a potent weed killer is necessary for productive results, but it should never compromise your or your pets’ safety. A good weed killer contains no health-harming ingredients. In case of any precautions, the weed killer packaging should state them clearly.

Rainproof

Suppose you apply a weed killer on affected areas and it starts raining immediately. If the weed killer isn’t rainproof, it would easily wash away. It’s also not possible to sprinkle such weed killers on wet surfaces. You must wait for them to dry before application. Instead of going through these hassles, you should expand your budget and buy a rainproof weed killer.
