What to Consider Before Buying the Best Crabgrass Killer

A homeowner should have a rough idea of what to consider before purchasing a crabgrass killer. The following are some of the factors.

1. Toxicity

Weed killers can be harmful to some plants. The good news is that most crabgrass killers won’t damage any of your other grasses. This could, however, include some other weed species, which might require to be treated differently. Don’t use the solution near small children or pets, also avoid areas around gardens.

Most crabgrass sprouts on the brinks of lawns, which makes it simple to remove and spray without getting exposed to animals. Besides, don’t breathe in the solution while spraying. This can happen in case you are not careful enough, especially when used with a spray nozzle. However, most brands have comprehensive directions making the process easy and a non-issue.

2. Application method

Herbicides are obtainable as either dry granules or liquid sprays. Granules are easy to apply uniformly with an appropriately calibrated lawn spreader. Store any leftover product in a cool, dry place until its next use. Pro-emergent or pre-emergent weed –an-feed applications for lawns come as granules.

Liquid sprays attest useful for broadcasting over large areas with a hose-end sprayer or spot treating small areas with a trigger bottle or a tank sprayer. They are sold as concentrated forms or ready-to-spray liquids. Ready-to-spray herbicides are handy and reduce the homeowner’s exposure to the chemical by excluding the mixing requirements.

When spraying liquids, you must be careful about the direction and the speed of the wind to avoid spray drift that can harm plants, not in the target location. Plan a “lane” to evade walking through freshly treated places.

3. Minimum usage rate

Before buying the crabgrass, be sure of the minimum usage rate for crabgrass prevention. These products have different usage ratings depending on the potency. You may have to apply it many times before you see the outcome.

A highly potent crabgrass killer product may need less regular use but may harm other grasses. Then again, the low potency crabgrass killer may require frequent application.

4. Selective vs. Non-selective

Herbicides are available as either selective or non-selective formulas. Selective herbicides control particular weed categories, like broadleaf weeds or grassy weeds. The ingredients in these types of weed killers should be harmless for non-target plants such as lawn grass while killing target plants such as crabgrass.

Constantly read labels on selective herbicides to be sure they will work for you. A product that is labelled as grassy weed killer may or may not control crabgrass, and it may or may not be rated for use in the area you plan to apply it.

Non-selective herbicides kill all kinds of plants. These are handy in places where you do not require plants, such as driveway cracks or mulched tree rings. Non-selective weed killers also can benefit in preparing for landscape face-lift, like creating a new flower bed or laying new sod.

5. Product restrictions

Nevertheless, these products might cause allergies in delicate people and this means it has been restricted in densely populated places. Therefore, before purchasing a crabgrass killer, you should check to see whether it is banned in your location.

Temperature controls the target weed as well as the efficiency of the weed killer. Weeds are most vulnerable to herbicides as they are growing actively. Crabgrass seeds sprout when the soil warms to about 50-degrees in the spring. In summer, the crabgrass plant matures and produces more seed until it dies when the cold climate comes.

A spring use of pre-emergent might be enough to get rid of crabgrass in a cold-weather place. in a warm-weather location, using pre-emergent frequently throughout the season, if required, alongside spot treating with post-emergent herbicide efficiently controls crabgrass.

7. Prevent or kill

Do you want to prevent the crabgrass or kill it? It is really difficult to find a product that can do both of these things. Nevertheless, you should decide how often you are available to apply the product. In case you are looking for something that will kill and prevent the crabgrass from growing back, you should bear in mind how expensive this attempt can become.

8. Coverage

The most crucial element is to know the competence of the product. The efficiency depends on the ingredients as well as the strength of the formula. Some products need high concentration and others need dilution usage. It is better to select a product that doesn’t require many applications to get the best value for your money.

9. Additional features

Many of these products have the capability of killing other weeds as well. Nevertheless, you don’t need to always put your attention on this. In case you have a dandelion issue and a crabgrass issue, you should look for something flexible enough. Besides, this flexibility will be fairly expensive, as you need to bear in mind as well.

Another outstanding feature to look at is whether the product is weatherproof. If your product can be rainproof for around 2-hour, this will make it effectual to be applied during the wet season as well. The best crabgrass killer should have this feature.
