Enjoy growing your own garden with our Canadian red rhubarb bulbs. This cool season perennial can return for up to 20 years once established. Chefs often use this ingredient to add a fresh flavour to pies or other desserts. Rhubarb should be planted in a sunny area and given plenty of nutrients for strong and healthy growth. Planting guide: When to plant - January to May. How far apart - Plant - 3 ft/90cm. Soil requirement: soil should be rich, and plenty of manure or compost can be dug in to enrich the soil. How to plant: Position the plant in full sun or partial shade. Flowering height - 20"/50cm. Planting depth - 1"/3cm. Harvest - June. Care guide - Young stems are pulled away from the crowns as they attain sufficient size. Never take too many from one plant, as this weakens it. And for the same reason, it is not wise to continue pulling after July. Plants remain in the soil for many years.
