When to plant spinach?

Spinach can tolerate lower temperatures and has a wide range of suitable temperatures for growth, from 5°C to 20°C. The most suitable growth temperature is around 15°C. Spinach can adapt to a variety of climatic conditions, but it is more suitable for planting in cool seasons. High temperatures in summer may affect the quality of spinach. Let’s learn below: When to sow spinach?

When to plant spinach?

Spring spinach is usually sown when the temperature rises above 5°C in spring. The best sowing period is March, and it can be harvested one to two months after sowing.

Summer spinach is highly heat-resistant and grows fast. The sowing time is generally from May to July, and the harvesting period is from June to September.

Autumn spinach is highly heat-resistant and is suitable for sowing from August to September and harvesting from September to October.

Winter spinach is very cold-resistant and is usually sown from mid-October to early November and harvested around the Spring Festival.

Spinach Growing Conditions

1. Temperature conditions

Spinach is a crop with strong cold resistance. Its seeds can germinate at 4°C and the most suitable growth temperature is 15-20°C. The above-ground part can withstand short-term sub-zero temperatures.

2. Lighting requirements

Spinach is not sensitive to day length, but full sun helps promote growth. Under long-day conditions, spinach may bolt and flower.

3. Water requirements

Spinach has larger leaves and requires more water. The soil should be kept moist, as drought conditions will affect the growth and quality of spinach.

4. Soil conditions

Spinach adapts to a variety of soil types, but loose, well-drained, slightly acidic to neutral soil (pH 6.5-7.5) rich in organic matter is most suitable.

5. Fertilizer requirements

Spinach likes fertilizer, so before planting, sufficient base fertilizer should be applied, mainly organic fertilizer , and nitrogen fertilizer and appropriate amounts of phosphorus and potassium fertilizers should be applied in time during the growth period.

In general, when planting spinach, you should choose a plot with fertile soil and good drainage. Before sowing, the seeds can be soaked to speed up germination.
