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.
Take these small seeds and plant them two inches deep in a pot with well prepared soil. The soil should be loosely packed inside the pot. You should plant one seed per pot. It is better you try to grow a mango tree in a pot first because it is easy to keep control. Also, place the pots in the sunniest part in your garden. Sometimes, the seed sprouts even when you wash it well and put it on a plate. However, putting it in the soil will give rise to a healthy tree eventually.
