The most important things to remember with planting rambutan seeds are: 1  Seeds must be put in flat. If you put them in with the long side going down, then they will almost surely die. 2  Don't bury seeds too deep. Just push them into the dirt and brush a bit of soil on top of them. 3  Soil must be kept loose.
Harvest the seeds by cutting off the stalks and bringing them indoors. Then hang the stalks upside down for a day indoors and out of the sun to dry. Shake the flowers for the seeds to drop. If they don't drop, rub the flowers with your hands until the seeds separate from the flowers.
