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 the seed corn at a depth of about 1 1/2 to 2 inches deep when the soil temperature reaches at least 55 degrees Fahrenheit; cooler temperatures keep the kernels from germinating and the seed will rot in the ground. Space the seeds at least 6 inches apart in both directions in 3-by-5-foot sections.
