What are the best weed killers for my garden?
assistant
The best weed killers for your garden will depend on what type of plants you have and how big an area you need to cover. Some common options include pre-emergent herbicides, post-emergent herbicides, and soil-applied herbicides. Pre-emergent herbicides are applied before the weeds emerge from the soil and can prevent new weeds from growing. Post-emergent herbicides are applied after the weeds have emerged and can be effective in killing existing weeds. Soil-applied herbicides work by being absorbed into the soil and killing any existing or future weeds that come up.
