The price of spinach tends to come down as temperatures rise. Data from the Xinfadi Market shows that the wholesale price of spinach is 0.8-1.8 yuan [0.12-0.27 USD] per 0.5 kg, which is a decrease of 23.53% in comparison with last week.

The spinach currently on the market mainly comes from two production areas: the area between Hengshui and Handan in Hebei; and the area between Taian and Zibo in Shandong. The spinach from Shandong is packaged in bags in the production areas and directly transported to the market for retail. The price is relatively low. The spinach from Hebei is bundled in the production areas and repackaged in the market according to client demand. The price is relatively high.

The current supply of spinach mainly consists of greenhouse spinach. As temperatures increase, the spinach will grow quicker, and the production volume will increase. When the supply volume grows, the price falls. When the temperature rises even higher the greenhouse spinach will gradually be replaced by open-field spinach, which is much cheaper because the production cost is lower.
