<human>:  How do I plant tomato plants?
<bot>: To plant tomato plants, start by finding a location in your garden or yard that gets plenty of sunlight, at least 8 hours a day. Prepare the soil by digging a hole about twice the size of your tomato plants’ pots. Place the plants in the hole and fill it with soil. Then water your plants deeply. Lastly, mulch the soil with hay or straw to prevent weeds from growing and retain moisture in the soil.
