How to sprout celery seeds in hot weather
The suitable temperature for celery seed germination is 15-25°C; above 30°C germination becomes difficult. When sowing celery in hot weather, the following seed treatment methods can be used to promote uniform germination. Variable temperature treatment: after drying the seeds in the sun for 1 day, soak them in clean water for 24 hours, changing the water every 8 hours, then remove them, rinse them clean, wrap them in damp gauze, and place them at 5°C...
Celery seeds are small, have a thick coat, and contain oil glands; the most suitable germination temperature is 20°C, and under hot, dry conditions sprouting is slow. In production, when sowing in late summer and early autumn, cold treatment is often used to promote germination. For example, to sprout seeds by hanging them in a well: first soak the seeds for 12-14 hours, rub and rinse them clean, then put the seeds in a gauze bag or mesh bag and hang it in the well 30-60 cm above the water surface to sprout, rinsing once a day with well water; after 3-4 days, when 80% of the seeds have sprouted, they can be sown. In addition, the soaked seeds can also be mixed with moist river sand and placed in a cool place, or the soaked seeds can be put in a bag and placed directly in the freezer compartment of a refrigerator for low-temperature treatment; this can also promote the germination of celery seeds.
