Tomatoes generally prefer a warm environment, with the most suitable daytime temperature range being 25 to 28 degrees Celsius and nighttime temperature range being 16 to 18 degrees Celsius. If the temperature is lower than 15 degrees Celsius, the seed germination, pollination, fertilization and reddening process of tomatoes will be affected. If it is lower than 10 degrees Celsius, the growth rate will slow down and reproductive development will be hindered. Let’s learn together about when and in what season tomatoes are planted. When and in what season are tomatoes planted? 1. Planting time of spring tomatoes The suitable seedling age for open-field spring tomato cultivation is 50 to 70 days, that is, sowing should be carried out 50 to 70 days before planting. Spring tomatoes are usually planted after the late frost period when the local temperature stabilizes above 12 degrees Celsius. 2. Planting time for autumn and winter crops The autumn and winter crops are generally sown and seedled from mid-to-late July to early to mid-August, transplanted from mid-to-late August to early September, covered with film from mid-to-late September to early October, and harvested from late November to early February of the following year. 3. Planting time for winter and spring crops The winter and spring crops are sown from early November to early December, transplanted from mid-to-late January to early February of the following year, and harvested from early to mid-March to June. 4. Planting time for winter crops The overwintering crop is a large crop of cultivation. Generally, seedlings are raised from mid-to-late September to early October, transplanted in November, and harvested in January of the following year. Tomato seed treatment method 1. Soak seeds in warm water First soak the seeds in clean water for 1-2 hours. Then put the seeds in warm water at 55 degrees Celsius, keep the water temperature even and soak for 15 minutes, and continue soaking for 3-4 hours to germinate. When soaking seeds in warm water, the usual ratio is one part seeds to two parts water. Stir constantly and quickly to ensure that the seeds are heated evenly to prevent scalding. 2. Disinfection with chemicals Soak the seeds in clean water for 3-4 hours, then soak them in 10% trisodium phosphate solution for 20 minutes, wash them with clean water and then germinate them. Soaking seeds in 0.1% potassium permanganate solution for 15-30 minutes can effectively reduce the occurrence of tomato mosaic virus disease and early blight. The above is an introduction to the planting season of tomatoes. You can choose the season you want for sowing according to market demand and climatic conditions.
