How many days does it usually take for water spinach to germinate?

Water spinach , also known as water spinach and water spinach, is a widely grown leafy vegetable with good regeneration ability. It can grow again quickly after harvesting, so it can be harvested multiple times. Due to its rapid growth and high yield, water spinach has high economic value. So how many days does it usually take for water spinach to germinate?

The germination time of water spinach is affected by many factors, including seed treatment, temperature, humidity and other conditions. The specific germination time should be considered in combination with many aspects.

1. Seed treatment

The seed coat of water spinach seeds is thick and they germinate slowly when sown directly. In order to promote germination, the seeds usually need to be pretreated, such as soaking the seeds in warm water at about 30 degrees for 16-20 hours, then rinsing them with clean water and wrapping them with gauze, and germinating them at 30 degrees. During the seed germination period, keep it sufficiently moist and rinse the seeds with clean water once a day. When 50%-60% of the seeds are white, they can be sown.

2. Germination time

Water spinach seeds that have not been treated for germination may take about three weeks to germinate, and the germination rate is low. Seeds that have been treated with germination will usually germinate about a week after sowing, and the germination rate is relatively high.

3. Temperature requirements

The germination of water spinach seeds requires a temperature of more than 15 degrees, and the temperature of the axillary buds must be kept above 30 degrees in the early stage of germination, so that the germination can be rapid and uniform.

4. Soil moisture

Keeping the soil moist is essential for water spinach seeds to germinate. During the first few days after sowing, the soil needs to be kept at an appropriate moisture level.

To sum up, under suitable conditions, the water spinach seeds that have been germinated usually take 7-10 days to germinate. Ungerminated seeds may take longer, about three weeks. Therefore, in order to speed up the germination speed and improve the germination rate, it is recommended to carry out appropriate germination treatment on the water spinach seeds before sowing.
