Tomatoes generally take between 50 to 100 days to grow from seed to harvest, depending on the variety and growing conditions. Early-season tomato varieties may mature in about 50 to 60 days, while mid- to late-season varieties can take 65 to over 85 days

. The growth process includes several stages:

• Germination: 5 to 10 days for seeds to sprout

• Seedling and early growth: 5 to 7 weeks indoors to develop true leaves and roots

• Vegetative growth: 20 to 25 days after transplanting, when vines and foliage grow rapidly

• Flowering and pollination: about 20 days, with flowers appearing and pollination occurring

• Fruit formation and ripening: 15 to 30 days for fruit to grow and develop color, usually red when ripe

Environmental factors like temperature, sunlight (8-10+ hours/day preferred), soil quality, and watering also significantly influence the growth rate and time to harvest. Tomatoes thrive in warm soil and full sun; cooler weather or insufficient nutrients can delay fruit development

. In summary, expect about 2 to 3 months from transplanting seedlings outdoors to harvesting ripe tomatoes, with total time from seed sowing to harvest around 60 to 100 days depending on the variety and conditions
