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.
Select a ripe sapote fruit and cut it open with a knife. Extract the seeds and rinse them of all pulp. Crack the coat of each seed before planting to increase chances of germination. Place a seed between two wooden boards and apply light pressure to the top board. A hairline crack in the seed is ideal. Plant sapote seeds in soil-free potting medium, no more than 14 days after harvesting, since sapote seeds do poorly in storage. Make sure that the pointed side of each seed faces up 1/2-inch from the surface of the soil. Water each seed deeply.
