Follow Instructions on How to Use a Weed Killer

After finding out what weed you are killing and the best product to use, you now need to ensure that you follow the instructions given carefully. This should help you not to miss anything important.

Every detail is imperative as it might be the difference between you killing the weeds in your lawn or giving them space to multiply. Again, you might use it wrongly and it ends up affecting your lawn.

There is a specific amount of weed killer that you should use, so make sure that you follow that to be on the safe side. This is one way of ensuring that you are effectively killing the weeds in your lawn.

Consider Spot-Killing the Weeds

Removing Crabgrass Naturally

One of the ways you can use to ensure that you destroy the weeds growing in your lawn is to do spot-killing.

If, for example, you are having broadleaf weeds in your lawn, you should use the least amount of herbicide as possible to kill the weeds. This is where spot-killing comes in.

You will notice that these weeds will be at different places in your lawn, but they are not evenly distributed. For this reason, what you should do is to spot where they are and then use a broadleaf weed killer to rid your lawn of them.

We're huge fans of Bonide (BND066), it not only works on Broadleaf, but Crabgrass and other weeds as well!

For you to do this, you will need a small pressure sprayer to spray the herbicide exactly where the weeds are. The advantage of using this method is that it saves you money and time. Additionally, it prevents you from introducing chemicals to your surroundings.

Get rid of Recurrent Grassy Weeds One by One

Perennial weeds can be problematic because they keep on coming back after year after year. If you fail to kill them, they will prove to be a headache and difficult to deal with.

Part of what makes perennial weeds to keep on invading your lawn and garden is because of their wide underground root systems.


It is not easy to kill them. In fact, some weed killers are not enough to get rid of them. If you choose to pull them, you will only manage to uproot some of them and the remaining roots will quickly give rise to others.

Again, as you uproot them, you are likely to uproot the good grass. Therefore, the best thing for you to do is to kill these weeds one by one.

​An example of a perennial weed is Quack grass. The best solution to such types of weeds is to use a non-selective weed killer like Roundup. For this one, you have to be very careful as you use it because it can destroy your lawn.

For effective and safe use of this weed killer, you only need to apply it to the perennial weed itself without touching other areas. Wear a chemical-resistant glove and dip it into the weed killer.

The glove will protect you from any harm from the chemical. Once you have applied the weed killer over the grass blades, it will absorb into the blade all the way to the roots.

It will, in turn, kill the plant. Expect to see results in a few days. Most of the weeds will die but for those that will survive, more weed killers will be needed to kill them completely.

Lawn and garden care requires you to kill weeds whenever they begin to sprout. If you fail to get rid of them at the right time, they will have negative effects on your lawn.

Essentially, the best thing to do is to have regular maintenance of your lawn and garden to make sure that you prevent weeds from growing.

Well, you might not be able to completely avoid weeds from growing, but you can prevent them from spreading.

Remember to always use the right weed killer for effective results.
