Lychees are a very sweet fruit often used in Asian desserts.
Sprinkle the seeds liberally but not too thickly on wet sand. Cover with chopped, wet straw about 2 inches deep. They germinate quickly - in about 4-5 days. During this time, add extra water if it is needed to keep the straw wet. You can transplant them into the field as soon as they germinate. Plant them in a lightly shaded spot.
