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.
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.
