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.
Germinating rambutan seeds and properly caring for the seedlings give the plant a healthy start. Choose a fertile growing medium, such as topsoil mixed with compost or manure. The added nutrients help speed up germination and seedling growth. Plant the seed horizontally with the flat side facing down.
