Spinach can be planted all year round. Because of its different planting time, spinach can be divided into four varieties: spring, summer, autumn and winter. The four varieties have different light intensity and duration.

The planting time of spring spinach is in early spring March. When the temperature rises above 5 degrees after the beginning of spring, it can be sown and harvested one to two months after sowing.

In order to ensure the yield, sowing about 3.5kg per mu, watering once after sowing, covering the soil with 2-3cm, keeping the soil moist, the seedlings can be ready in about a week.

2. Field management

Spinach has strong growth power, and it can grow on its own as long as it emerges, but in order to ensure its yield, it is necessary to carry out inter-seedling when it grows true leaves, which can be weeded in time at the same time. Grow 3-4 true leaves can be irrigated once thin fertilizer water, fertilization should not be too thick, lest excessive fertility lead to root burning death.
