Roundup is a weed killer that many people know. Some people think it is controversial because the company that makes it, Monsanto, makes some heavy chemicals. However, Roundup is good at killing weeds.

Roundup is a weed killer that you can use to get rid of weeds on different surfaces. It comes with a pump and sprayer, so you don’t have to mix it yourself. You can use it on mulch beds, driveways, and patios.

Compare-N-Save is a good budget option for patio weed killers. The option we looked at comes in 1-gallon containers and can cover up to 25,000 square feet.

What To Look For in a Weed Killer

The following are some of the most significant aspects to consider when purchasing a weed and grass killer.

1. Active Ingredients

Different brands of weed killers have different ingredients. Some kill every kind of weed, while others are specific to one type of weed. Before buying a weed killer, know what type of weed you want to kill.

Products usually come with a list of weeds that the product can kill. Read the list and the instructions on using the product for the best results. Checking reviews from other people who have used the product can also be helpful.

2. Selectivity

Herbicides can be selective or non-selective. Selective herbicides target specific plants without affecting others. To protect your plants, use this type.

Non-selective weed killers kill any kind of plant it touches. It is perfect for getting rid of weeds in a large area or an area where you don’t want any plants. Non-selective herbicides are the best for getting rid of weeds on driveways, patios, and walkways.

3. Application

Herbicides come in many brands, and each brand has a different way of being applied. Some common methods of application are as follows:

Trigger spray application uses a gun-like spray bottle to put the solution on the leaves or foliage. You don’t have to mix it with water or any other solutions.

  • Pump applicator:

The herbicide may come in a ready-to-use solution or as a concentrate that you will need to mix before spraying. When spraying large areas, you will need a sprayer tank.

  • Granules:

Some weed killers are available as powders or crystals. You put them on the weed without dissolving them, and then you splash water on it to help the granules penetrate and dissolve into the plant.

4. Quantity

You will need a lot of weed killers to cover a large area like a driveway. You can use a pump sprayer to put the weed killer on faster. The best weed killer to use for this is a concentrate that you can dilute with water and then put on using the sprayer pump.

For small patches of weeds or undesired grass, use a weed terminator. This usually comes with an applicator. For larger spaces, you can use granular herbicide.

5. Residual Activity

Residual activity means how long the weed killer can stay effective after putting it down. You need a weed killer with high residual activity for driveways, patios, and walkways. That way, you won’t see any more weeds growing there forever.

Low residual activity herbicides are the best for lawns, gardens, and landscapes. You can apply them before you plant your desired crops, before they germinate, or after they have grown.

6. Safety

When dealing with herbicides for cannabis, it’s critical to exercise extreme caution. The majority of them are hazardous to one’s health if breathed or eaten. The following are some of the most important safety precautions:

  • Wear protective gear to avoid contact with your body
  • Do not spray while kids, pets, or other family members are around
  • Properly dispose of empty herbicide bottles or containers
  • Store away from the reach of children.
  • Do not spray on edibles such as fruits, vegetables
  • Always read and follow label instructions before using

If you are not comfortable using a chemical weed killer, you can hire a professional weed control service. Another option is to use natural ways to get rid of weeds between pavers and cracks in your hardscapes.
