Rhubarb crowns are best planted in early spring when the roots are still dormant or plants are just beginning to leaf out. Rhubarb can also be planted in the fall after dormancy has set in. Each plant will require approximately one square yard of space. Loosen the soil to a depth of 10 inches. For each plant, prepare the soil by adding 3 to 4 inches of compost or well-aged manure and a handful of fertilizer that is relatively high in phosphorus and potassium, such as 5-10-10. Cover the crowns with no more than an inch or two of soil.
Dig around the base of the rhubarb clump. Insert the blade of your spade at least 6 inches into the soil and lever it backward to lift the rhubarb root mass. Slide the spade beneath the root mass and lift the entire root clump from the bed. Locate the buds on the rhubarb crown, near the top of the root mass.
