About Rhubarb
Rheum rhabarbarum is an moderate-growing edible plant in the Polygonaceae family. It reaches around 80 cm tall at maturity.
Where to grow Rhubarb
Rhubarb suits cool-temperate and warm-temperate climates and grows best in full sun and part shade or morning sun. It is frost hardy and shrugs off cold winters.
Soil & planting
Rhubarb does best in free-draining and loamy soil. Dig in plenty of compost before planting, water in well, and mulch to keep roots cool.
Watering & feeding
Rhubarb is regular, moderate watering. Feed regularly through the growing season for the best crop. In its first year, water deeply once or twice a week to settle the roots in, then taper off as it establishes.
Pruning & care
Tip-prune Rhubarb in spring to maintain a dense, shapely habit. Overall it is low maintenance.
Using Rhubarb in the garden
Rhubarb earns its place for edible harvests.
Companion planting & design
For a cohesive, low-care bed, pair Rhubarb with other plants that enjoy the same regular, moderate watering and cool-temperate climate. Group three or five together for impact rather than dotting single plants through the garden.
Good to know
Note that it is toxic to cats and dogs, so site it away from pets that chew.
