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.
How to plant. 1  Rhubarb can be grown from seed or as plants purchased from your local garden centre. 2  Choose the right variety for your patch, prepare the soil, then plant your rhubarb in late autumn to early winter.  The depth should be such that the top of the plant is at, or just below the soil surface.
