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.
Step 2. Sprout the seed. If you're starting with a whole avocado, remove the pit and gently wash it, to remove any residue. Allow the seed to dry for 24 hours and then insert toothpicks into the seed. Push the toothpicks in about 1/4 inch, circling the pit around the approximate center.
