Chinese water spinach, also known as hollow heart vegetable or swamp cabbage, is a vegetable that is easy to grow, and many people cultivate it at home. Typically, under suitable conditions of soil, water, and temperature, Chinese water spinach seeds can germinate and sprout within about 10 days. But what if your Chinese water spinach seeds haven't sprouted after 10 days of sowing? Let's find out together.
What to Do If Chinese Water Spinach Seeds Don't Germinate After 10 Days of Sowing?
If Chinese water spinach seeds fail to germinate within 10 days of sowing, it could be due to lack of pre-germination treatment. Before sowing, soak the seeds in clean water for about 12 hours, then place them in a greenhouse environment with a temperature of around 25°C for pre-germination. This helps to improve the germination rate of the seeds. If Chinese water spinach seeds don't germinate after 10 days, consider re-sowing.
How to Promote Faster Growth of Chinese Water Spinach Seeds?
-
Pre-Soaking for Germination: Chinese water spinach seeds have hard seed coats, so it's advisable to pre-soak them before planting. Simply soak the seeds in warm water for about 1-2 days, then remove and allow them to air dry in a cool place.
-
Prepare the Planting Site: Prior to planting, prepare the planting site by deep tilling to ensure the soil is loose and fertile. Incorporate organic compost to improve soil fertility, promoting vigorous growth of Chinese water spinach.
-
Sow the Seeds: After pre-treatment, sow the seeds directly on the soil surface. Cover them with a thin layer of soil, water lightly to keep the soil moist, and then cover with a layer of plastic film to provide warmth and moisture retention. Once seedlings emerge, remove the plastic film to allow sunlight exposure, encouraging faster growth.
Conclusion
In conclusion, if Chinese water spinach seeds fail to germinate after 10 days of sowing, it's essential to ensure they undergo proper pre-germination treatment. Pre-soaking the seeds and providing optimal environmental conditions can significantly improve germination rates, leading to successful cultivation of Chinese water spinach.
