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.
Seed must be very fresh, less than a week old, to be viable and all the pulp should be cleaned from it. To grow rambutan from seed, plant the seed flat in a small pot with drainage holes and filled with organic soil amended with sand and organic compost. Place the seed in the dirt and lightly cover with soil. It takes between 10-21 days for the seed to germinate.
