Below are the essential things you must consider before purchasing the best brush killer on the market.

– Type

In brush killer, the first thing that you should consider is its type. A brush killer has two kinds, including non-selective and selective. The non-selective brush killer eliminates everything that comes in contact with it. Therefore, you should try to be more careful while using this type. Also, avoid this unit’s contact with the grass and plants you do not want to kill.

On the other hand, the selective brush killer only kills specific plants. The selective brush killer does not do any harm to the grass it touches. Also, these types are relatively weaker compared to the non-selective brush killer.

Therefore, if you want to remove specific plants, weeds, or brushes from your lawn, then the selective brush killer will be ideal for you. But in case you need to cover a greater area, then prefer the non-selective one.

– Quantity

Each brush killer usually comes in a bottle or a container that holds a different quantity of liquid. Check the quantity of the liquid before buying.

You should invest in a brush killer with a greater quantity for more excellent coverage. Simultaneously, if you have a small area to clean, you can prefer a low quantity brush killer. Therefore, first, you should look at your needs and decide which one will be best for you.

– Rainproof

What if you spray the brush killer and rain washes it away and minimizes its effects? Well, to deal with it, you should only choose a product that has a rainproof option. Experts also recommend using the brush killer on a dry, sunny day. However, if you live in such a place with unpredictable weather conditions, then you should not ignore this factor.

Most of the brush killers become rainproof after a few hours. You should invest in such rainproof products to help you get the same results even if it starts raining in that area.

The time that a brush killer will take to become rainproof varies from product to product.
Make sure that the product you choose requires a short time to become rainproof. Some products become rainproof within a few minutes, while a few may even take up to 24 hours. However, if you live in a location where it rains less frequently, you can avoid this factor.

– Form

Before investing in any of the brush killers, you should also check it form first.

Concentrated and ready-to-use are the two forms that you will find with the brush killers.

You will need to mix the concentrated form with water to make it work for you.

On the other hand, you will not require mixing anything with the ready-to-use solution. You can apply the ready-to-use solution anytime you want. Both these forms give effective results when it comes to removing weeds and shrubs. As per your ease, you can pick any of the forms.

– Safety

It would be best if you also considered the safety factor while buying the brush killer. They contain a few active ingredients that can be harmful. Ensure to be careful while operating these brush killers as they can injure you.

Try to choose the brush killer that is safe for the environment as well. Also, examine whether the product is pet-safe or not. If the product is not pet-safe, keep your pets away while applying it. You can learn about all such information from the label present on the product. Therefore, try reading the label before using the brush killer.

It gives a rapid outcome and becomes rainproof after 30 minutes of use. Because it is in a concentrated form, you will need to mix it with water.

However, suppose you prefer a ready-to-use formula instead of a concentrated form. In that case, you can select the Ortho 475705 Brush Killer. Within 2 hours, it becomes rainproof and gives top-quality cleaning.
