1. If you sow the remaining grapefruit seeds directly in spring, you can't germinate that year (the second year), because the grapefruit seeds need a certain period of low temperature to complete their natural dormancy (post-ripening period), and the naturally dormant seeds can germinate normally after sowing.
2. Before winter (165438+1October), low-temperature sand storage can be used to help fruit tree seeds complete the natural dormancy period (post-ripening period), and most fruit seedlings are raised in this way. Because the method steps are complicated, I won't go into details here. If there are only a few seeds, it is troublesome to do so. You can plant them directly in a flowerpot with a sowing depth of 3-5 cm.
3. After sowing, water it, put it outdoors, spend a long winter, and let the seeds complete natural dormancy. Water is poured once in the first 7 days, once in 20-30 days after freezing, and once in 5-7 days in the first half of March. In the first half of April, your grapefruit will sprout. Strengthen the management of soil, fertilizer and water after emergence, and transplant it in the spring of next year.
