Small tomato seeds can grow within 7 days to 14 days after germination and sowing. Look at the temperature and soil when sowing.
growth cycle
Tomato is a perennial herb in tropical regions, but it is cultivated as 1 year in frost regions in temperate regions. Its growth and development process has certain stages and periodicity, which can be roughly divided into four different stages: germination stage, seedling stage, flowering stage and fruiting stage.

Germination stage: from sowing to the appearance of the first true leaf (heartbreak). At room temperature, this period is 7 ~ 9 days; The germination period is from seed water absorption to cotyledon unfolding to expose true leaves. At room temperature, it usually takes 10- 14 days from sowing to true leaf heart breaking. If the temperature is too low, seedling emergence will be slow. The process from germination to cotyledon development belongs to heterotrophic growth, and the nutrients needed for its growth are supplied by the seeds themselves, that is, from germination to seedling stage.
Seedling stage: refers to the period from the appearance of the first true leaf to the appearance of the first inflorescence. The suitable daytime temperature is 25 ~ 28℃, and the nighttime temperature is 13 ~ 17℃. The ground temperature in this period has great influence on seedling growth, and the suitable ground temperature should be kept at 22 ~ 23℃. The first flowering and fruit-setting period refers to the period from the first inflorescence to fruit-setting. This stage is the turning point of tomato from vegetative growth to reproductive growth and vegetative growth, which is directly related to the formation and yield of product organs;
Flowering period: 1 Inflorescence takes about 15-30 days from bud to fruiting. During this period, the plant not only continued to differentiate and develop flower buds and leaf buds, but also grew vigorously in nutrition, and the phenomenon of plant height increase and leaf growth appeared. Therefore, at this stage, it is necessary to adjust the relationship between vegetative growth and reproductive growth, not only to make vegetative growth full, leaves stout, stems stout and deep-rooted, but also to avoid virtual growth, prevent flowering and delay flowering and fruiting.
Fruiting period: from the first inflorescence to the end of harvesting (seedling pulling). In this period, fruits and seedlings grow at the same time, so it is a key task to solve the contradiction between vegetative growth and reproductive growth.
Why is the germination rate of tomato seeds low? Generally, tomato planting is seedling planting. Professionals have methods to improve the germination rate and generally buy seedlings.
How long does it take for a small tomato to grow? The range is from 1 10 days to 170 days.
The period from seed sowing and germination to the maturity of the first ear seed is the growth and development cycle. It is divided into four stages: germination stage, seedling stage, flowering and fruiting stage and fruiting stage.
First, the budding period
The development period is from seed germination to two cotyledons growing the first true leaf, usually 7-9 days.
Second, the seedling stage
The period from the first true leaf to the big bud is the seedling stage, which generally takes about 50 days at suitable temperature, 60-80 days in cold season and 40 days in high temperature season.
Third, the flowering and fruit-setting period
This period needs 15-30 days, and the early or high temperature growth time is short, otherwise it is long.
Four. Fruiting period
After flowering and pollination, the tomato fruit begins to swell in 3-4 days, the fastest is 7-20 days, the swelling reaches the limit in 30 days, and the coloring reaches maturity in 40-50 days.

Do the seeds of small tomatoes need to be dried before sowing? The seeds harvested by yourself are useless, and they are still big tomatoes. This thing is genetically modified.
Can small tomato seeds germinate directly in the soil without blisters? Directly in the soil, slowly absorb the water in the soil, and then germinate to adapt to the soil environment-permeability and water content.
What is the reason why tomato seeds only grow tall and have no leaves after germination? Too fast growth, insufficient illumination, too much watering and high liquid temperature may all cause it.

How long does it take for tomato seeds to germinate 10 days? After germination, there are only two bud leaves. Take care of them carefully, mainly to keep them moderate. When they are dry, water them. Be careful not to pour tap water directly. Tap water should be put in the basin for more than 24 hours before use, so that the chlorine in the water can volatilize, otherwise the buds will be burned to death. When the leaves grow above 10, they can be ready for transplanting. A flowerpot can grow 1-2 seedlings. When the leaves grow to 65,438+0 feet, Takaso can be fertilized. It will blossom and bear fruit in about two months, and the fruit will turn green at first. It will turn red slowly when you grow up. At this time, you should pay more attention to the sun, do support, and help the branches support the weight of tomato fruit.
