How to use Spectracide weed killer

As mentioned before, there are two types of Spectracide weed killers. Each has its ratio to be applied. The lawn weed killer should mix 10 tbsp of the herbicide with a gallon of water for a 500 square feet area.

Then the weed grass killer one requires 14 tbsp of its liquid to be mixed with a gallon of water for a 300 square feet area. The mixture of herbicide and water can be sprayed using a pressure sprayer.

Those mixtures effectively kill a weed, but is Spectracide weed killer safe for vegetable gardens? Surely no. Before spraying the herbicide, cover vegetables or other plants with a piece of cardboard or plastic.

Wear personal protection equipment (PPE)

Apply as the suggested usage and instructions only

Determine the size of the area and cover any desirable plants. If the vegetables or other desirable plants get sprayed, wash them immediately using water.
