Some weeds died off after 4-5 days, but others that would normally turn brown after 5-7 days took more than two weeks. I thought this Round-Up was not going to kill them as they stayed green for 2 weeks.

The weed-killer is effective on nuisance trees of 4-5' diameter when applied in the fall by slashing the bark with an axe and spraying into the outer layer of the tree. The herbicide causes the trees to wilt over 2 weeks to 2 months as it gets sucked down to the roots.

Buying Guide for Weed Killers

Weed killers, also known as herbicides, are effective tools for removing weeds from a garden or lawn. They are available in several forms, including liquid, granular, and aerosol sprays. Weed killers are usually made of synthetic chemicals, but some are made from natural ingredients. They are intended to be selective in the plants they target, which means they will target and kill the weed while causing no harm to the desired plant species. Weed killers can help control the growth of invasive plants in gardens, lawns, parks, and agricultural fields.

Some products are systemic, meaning they will be absorbed by the weed, whereas others are non-selective and will kill any vegetation they come into contact with. View some of the best weed killers on Amazon.

Weed killers are a type of herbicide that kills unwanted plants, or weeds, in gardens, fields, and other areas of vegetation. Weed killers work by interfering with the ability of plants to produce food or survive in the environment.

Fast Action 

Weed killers work quickly because they contain active ingredients that kill weeds at the root level. The active ingredients begin to penetrate the weed's outer layers and reach the root system as soon as the weed killer is applied. The active ingredients then begin to break down the weed's internal cells, killing it in hours or days, depending on the strength of the product.
