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.
Either will work, but the soil method will provide faster results. If the seed is started in water, insert three or four toothpicks in the seed about half way down the sides. Next, fill a small glass with water to the brim and place the seed in the glass, flat end down, so the toothpicks rest firmly on the brim.f the avocado seed is started in soil, fill a large container with house plant potting soil. Plant the seed so that the pointed end is about an inch above the soil surface.
