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.
Plant rambutan trees at least 33 feet apart. The roots spread considerably and need plenty of room to grow. If the trees are too close together, they may not produce a high yield of fruit. After a fruit harvest, apply 2.2 pounds of ammonium sulfate and 2.2 pounds of a 12-24-12 fertilizer per tree to the soil.
