Plant from autumn through to spring in a sunny position with free draining soil. The soil should be free of weeds and include plenty of well-rotted manure. Plant in rows spaced 90cm (35”) apart and ensure that the top of the crown sits 3cm (1”) below soil level, allow plenty of space around the plant so it can spread out. Resist the temptation to harvest any stems in the first year, as this will reduce the plants vigour. Earlier harvests can be produced by forcing the rhubarb, this simply means covering the crowns in early winter, to stop light from reaching the emerging rhubarb stems. You can use a bin or bucket, or a traditional terracotta rhubarb forcer – any cover that's at least 45cm high.
