The Best Homemade Weed Killer

Every gardener hates weeds. They are a pain to pick out one by one. It can be challenging work, depending on the size of your garden.

Making your weed killer at home might seem too good to be accurate, but it works just as well as store-bought weed killers.

You don't need to buy weed killers from the store. You can make your weed killers with things you have around the house. They will work just as well as store-bought weed killers. People have been using homemade weed killers for hundreds of years, and they work just as well.

Making your weed killers is that you know what is in them.

1. Homemade vinegar weed killer

You can indeed use vinegar as a weed killer. Vinegar contains acetic acid, which is effective in killing weeds. You can buy vinegar with different levels of acetic acid, but the most effective kind is 5% acetic acid in white vinegar.

What do you need for this weed killer?

Different types of weeds will die off at different speeds. A weed can die if you're trying to get rid of it. However, some weeds may take up to 14 days to break. If you are using this weed killer, we suggest waiting 21 days before reapplying.

Other Uses:
