Spinach (Spinacia oleracea )

Other names: Bo Tsai, Bo Cai.

Approx. 70~100 seeds per gram/ 10~14 gram per thousand seeds (M)

Spinach is a cool weather crop. Seeds prefer to germinate in cold weather. Optimal soil temperature for emergence is 10~18 °C/50~65°F. It can be planted when soil is workable in spring. Higher soil temperature ( over 20°C/68°F) may result in sharp decrease in germination rate. Seeding in summer is not recommended.

Spinach tends to bolt (seed-stalk development and flowering ) as daylength, temperature and plant density increase. Water stress and inadequate nutrients increase bolting risk. Exposure of young plants to low temperature (4°C/40°F ) also increases the risk of bolting.
