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.
To grow a rambutan from seed, first get some small pots or cups. They must have adequate drainage holes in the bottom so the tree roots don't start to rot. Fill the pots with organic soil that is amended with sand and organic compost so it is loamy.
