How to apply wintering fertilizer properly to spinach before overwintering
1. Sowing. Spinach is mainly broadcast-sown, though drilling is also possible. Under high-temperature conditions, germination is slow, so for early-autumn sowing it is best to soak the seeds to promote germination: soak the seeds for 12 hours, then treat them in a refrigerator at 4°C for 24 hours, and then keep them at 15-25°C to promote germination for several days; once most have germinated, they can be broadcast-sown. Sowing rate per mu...

The three-part spinach cultivation guide: master the key growing steps
Sowing: Spinach is mainly broadcast-sown, though it can also be sown in rows. Because germination is slow under high temperatures, seeds sown in early autumn should be soaked and pre-germinated: soak the seeds for 12 hours, then place them in a refrigerator at 4°C for 24 hours, then keep them at 15-25°C to sprout for several days, and once most have germinated, broadcast-sow them. Sowing rate per mu: 10...

What to Do About Spindly Overgrowth in Greenhouse Beans? Detailed Analysis of Causes and Control Methods
The causes of spindly overgrowth in summer vegetables differ at each stage. Practice has proven that greenhouse beans are most prone to spindly overgrowth during the summer, and the main causes can be grouped into two major categories: 1. Seedling-stage overgrowth. The main cause of spindly overgrowth in seedlings is excessively high temperature, especially when nighttime temperatures are too high and respiration consumes too much...
