Thrives in rich, well-drained soil. Loosen the dirt to a depth of at least 10 inches and mix in plenty of compost, well-rotted manure and a handful of fertilizer such as 5-10-10. Rhubarb plants are very heavy feeders and manure should be added to the soil every year. Plant the crown so that it’s covered with only an inch or two of soil. Allow each plant about one square meter of space.
