<human>:  How do I grow green tomatoes?
<bot>: To grow green tomatoes, you'll need to provide them with plenty of sun, water, and nutrients. Start by selecting a variety of tomato suited to your climate and that produces green fruit. Plant your tomatoes in a sunny, well-drained spot and water them regularly. Provide them with a balanced fertiliser and stakes or cages to support the plants as they grow. Harvest the tomatoes when they reach a light green colour, usually a few weeks before they would turn red.
