Detailed explanation of key points for cherry tomato seedling cultivation, teaching you to grow robust seedlings
Before sowing, seeds should first be disinfected and pre-germinated. For disinfection, use hot water soaking or chemical disinfection. Choose the soaking method selectively based on common local diseases.

Before sowing, seeds should first be disinfected and pre-germinated. For disinfection, use hot water soaking or chemical disinfection. Choose the soaking method selectively based on common local diseases.
Hot water soaking: soak tomato seeds in cool water for 10 minutes, then place them in 55°C hot water, stirring constantly and quickly to heat the seeds evenly, maintaining a uniform water temperature and soaking for 15 minutes. This can control leaf mold, canker, and early blight. Trisodium phosphate soaking: first soak in clean water for 3 to 4 hours, then place in a 10% trisodium phosphate solution and soak for 20 minutes, remove and rinse clean; mainly controls viral diseases.
After disinfection, soak the seeds for 6-8 hours, remove and rinse clean, then germinate at 25°C with warmth and moisture retention. During germination, rinse the seeds with warm water at about 25°C 1 to 2 times per day. Generally, the seeding rate is 5 grams per mu.
For winter and spring seedling cultivation, germination should proceed until more than 70% of seeds have sprouted (white root tips visible) before sowing; for summer and autumn seedling cultivation, sow the disinfected seeds directly.
