In which month can we eat spinach?

1. Early autumn spinach. Sow around August 20 and go on the market in mid-to-late September. Since the temperature is still high, you should choose heat-resistant and easy-to-germinate varieties, such as all-purpose spinach.

2. Autumn spinach. Sow in August, harvest in batches after 30-60 days, and go on the market from mid-to-late September to October.

3. Overwintering spinach. Start cultivation in early to mid-October and go on the market before the Spring Festival. It is advisable to choose varieties that are late in bolting, cold-resistant, and high in yield, such as pointed leaf spinach, spinach No. 10, spinach No. 9, etc.

Can I grow spinach in summer?

Spinach is a cold-resistant vegetable. The seeds can germinate at 4℃, the most suitable temperature is 15-20℃, the suitable temperature for vegetative growth is 15-20℃, and the growth is poor above 25℃. The aboveground part can withstand low temperatures of -6-8℃. The temperature in summer exceeds 30℃, which is not conducive to the growth of spinach, so it is not suitable for planting.

Why is it difficult to grow spinach in summer?

Spinach is difficult to grow in the summer because it often rains and the ground temperature is higher at this time. If the rain falling on the fields is too heavy, it will have a great impact on the roots and stems of spinach, causing root rot or the high temperature and high humidity environment at the roots causing the spread of diseases, which will cause the spinach plants to die.

Spinach likes cool weather and is cold-resistant. It can survive the winter in the open field in places with a winter temperature of -10℃. The optimum temperature for germination is 5℃~20℃, and the optimum temperature for growth is around 20℃. It will not grow well above 25℃.

Solutions for growing spinach in summer

The first is germination after sowing.

"The germination of spinach seedlings after sowing is very critical, because heavy rain often occurs after sowing, and it is very likely that the seedlings will have difficulty germinating due to the rain. In order to prevent the adverse effects caused by the low germination rate, I always slightly increase the sowing amount of spinach." Master Wang introduced.

The second is the issue of spinach management during the rainy season.

After the seedlings emerge, the next step is field management. One of the key issues is how to ensure that the spinach plants do not die. Currently, the main causes of death are rainfall and disease, which can also be attributed to weather reasons.

There are two ways to solve this problem. First, drain the water in time after the rain and use well water to waterlog the garden. It should be noted that there must be no water accumulation in the field after watering, otherwise it may cause root rot. Second, pay attention to prevent diseases such as damping-off, downy mildew, stem rot, and bacterial rot. After all the seedlings emerge, you can spray them with 600 times dilution of chlorothalonil or cymoxanil once. In the later stage, you can spray streptomycin and sinoprotinin to prevent bacterial diseases, which can effectively prevent the occurrence of dead plants.
