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.
Although it is possible to grow rhubarb from seed, rhubarb planting using root stock, or crowns, is the favoured method for growing rhubarb, especially in Northern climates. The best time to plant rhubarb from root stock or crowns, (also referred to as  rhizomes ), is in early spring. Once planted, it will thrive in the cooler spring temperatures and will really begin to grow once the soil temperature reaches above 40 Â° F.
