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.
Use individual 2- to 3-inch-diameter seedling pots or a larger seedling tray. Pots and trays must have drainage holes so the excess water can drain out. Water the soil before you plant so it's moist. Sow a single seed per pot, or plant the seeds 2 inches apart in rows set 2 inches apart in a tray. Large nasturtium seeds require deep planting, so plant the seeds 1/2- to 1-inch deep in the pots. Keeping the soil temperature near 70 degrees Fahrenheit and maintaining even moisture encourages quick germination.
