There are about 10,000 varieties of tomatoes in the world. There is a worldwide demand for them. These are used to flavor food.

1. Choose the right variety: There are two types of tomatoes: determinate and indeterminate. Determinate tomatoes grow to a certain height and produce fruit all at once, while indeterminate tomatoes grow continuously and produce fruit throughout the season. Choose the variety that suits your needs and space.

2. Start with good soil: Tomatoes need well-draining soil that is rich in organic matter. You can use compost or manure to enrich the soil.

3. Plant in the right location: Tomatoes need full sun, so choose a spot that gets at least 6 hours of direct sunlight per day. If you live in a hot climate, consider planting them in a spot that gets some afternoon shade.

4. Plant at the right time: Tomatoes are warm-season plants and should be planted after the last frost date in your area. In Denver, Colorado, the last frost date is usually around May 15th.

5. Water regularly: Tomatoes need regular watering, especially during dry spells. Water deeply once a week, making sure the soil is moist but not waterlogged.

6. Fertilize: Tomatoes are heavy feeders and need regular fertilization. You can use a balanced fertilizer or one that is high in phosphorus to encourage fruiting.

7. Prune and support: Prune your tomato plants to remove suckers and promote air circulation. Use stakes or cages to support the plants as they grow.
