Large spinach planted in October can usually continue to supply fresh spinach during the Spring Festival. This result depends on many factors, including planting conditions and environmental factors. Spinach has strict requirements on climate and soil, and suitable temperature and humidity are helpful to its normal growth and development. If the planting environment is too cold or improperly managed, the growth of spinach will be affected, and the quality will decline or even it will not grow normally. When planting large spinach, it is necessary to pay attention to providing suitable temperature and humidity conditions and reasonable management measures, such as heat preservation and moisture retention. This can increase the success rate of spinach growth and ensure that it can still supply fresh spinach during the Chinese New Year.
