The most important things to remember with planting rambutan seeds are: 1  Seeds must be put in flat. 2  Don't bury seeds too deep. 3  Soil must be kept loose.  Soil must be 1  loamy. It will take about 10-21 days for the rambutan seed to germinate.
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.
