Human: What is the best way to keep my garden weed-free? Assistant: 
The best way to keep your garden weed-free is to pull any weeds you see as soon as possible. Make sure to remove them from the soil and prevent them from growing back by mulching or covering the area with a layer of newspaper or cardboard. You can also use natural deterrents such as garlic, onion, and hot peppers to discourage weeds.
