If it's fun, just put litchi seeds in a flowerpot and water them. You don't need blisters. Just spit it out from your mouth after eating lychee. However, litchi seeds with large core (above 10 mm in diameter and smooth in appearance) and small core (only 5-6 mm in diameter and wrinkled skin) can not germinate. It is also possible to plant seeds in Shandong in summer. The key is to find litchi seeds and large-core varieties. Commercial litchi, only a few varieties, such as the late-maturing variety (Hu Aizhi), are big-seeded and can germinate and take root. As long as there is water, a long and thin trunk will grow in ten days, red and tender, white or beige in a few days, light green and finally green. There is no special requirement for planting, which is simpler than planting many crops. It's just that litchi is afraid of cold and will die when it encounters frost.
