Crabgrass Killer for Lawns: Quick Buying Guide

Before getting into the specific products, here are a few quick tips on how to choose the best crabgrass killer for your lawn.

Weather Conditions

Crabgrass thrives on dry and hot weather. Many weed killers can only be used when it is sunny out or when it is not raining. So, make sure you treat your lawn at the right time of year.

Size of Area

How much product you need will depend on how large your lawn is. If you are only treating a small area, then a concentrate or a pre-mixed product might be best for you. If you are treating a large area, then an economy-size product might be more economical for you.

Weed Killer Type

There are two types of weed killers: selective and non-selective. Selective weed killers kill specific plants while leaving the rest of the lawn unharmed. Non-selective weed killers kill all plants that they come into contact with. If you are only targeting crabgrass, then choose a product that is specifically meant for killing crabgrass. Many weed killers can work, but it’s important to get something that is made for this specific job. But if you are targeting other weeds in your lawn as well, then a non-selective weed killer is the better choice.


Price is always important! It doesn’t hurt to compare prices before purchasing. Many companies will offer discounts on multiple weed killers at the same time (like buying 2 weed killers together), so make sure you take advantage of that if your budget is tight! If you have enough money to purchase multiple products, then go for it. That way you will be sure to get the job done. However, many of these products are very inexpensive so you might only need to purchase one. When it comes to your lawn, there are no shortcuts. The more you put in, the better the results will be.
