How long does it take for tomatoes to grow?Tomatoes Growth cycle
The period from tomato sowing and germination to maturity of the first ear fruit seed is the growth and development cycle. Divided into four stages: the germination period, the seedling period, the flowering and fruit setting period, and the fruiting period.
⑴ Germination period
The period from seed germination to the emergence of the first true leaf from two cotyledons is the development period, which is generally 7-9 days.
The period from the appearance of the first true leaf to the appearance of the large flower buds is the seedling stage. The seedlings generally take about 50 days at a suitable temperature, 60-80 days in the cold season, and 40 days in the high temperature season.
⑶ Flowering and fruit-bearing period
This period takes 15-30 days. Early maturity or high temperature cultivation takes a short time, and vice versa.
Tomatoes begin to swell 3-4 days after flowering and pollination, the fastest in 7-20 days, the swelling reaches the limit after 30 days, and they begin to color and reach maturity in 40-50 days.
How long does it take for tomatoes to grow? Tomatoes Planting area and harvest time
Tomatoes are suitable for growth and development in the season when the average monthly temperature is 20-25℃, and the temperature adaptation range is 10-35℃.
Different growth stages of tomatoes have different requirements and responses to temperature. The most suitable temperature for seed germination is 28-30°C, the lowest is 11°C, and the highest is 35°C. If it is lower than 11°C, it is easy to cause rotten seeds. The most suitable day temperature for seedling and plant growth is 24-28℃, and night temperature is 15-18℃. When the temperature is lower than 10℃, the growth will decrease; when the temperature is lower than 5℃, the stems and leaves will stop growing; when the temperature is -1℃–2℃, it will be cultivated in early spring and early spring, or cultivated in spring. The electric hotbed nursery is more suitable for sowing and nursery in mid-to-late December.

Autumn tomatoes are cultivated or broadcasted from July to August, planted from August to early September, harvested in early October, and seedlings are drawn in late November.
⑷ Tomato planting time in the southernmost part of the United States
