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.
Rhubarb grows well in almost any garden soil, although, like most plants, it does not like soggy soil. Ideally, the area where you are planning to plant rhubarb should have well-draining soil with compost or well-decayed manure worked into the soil. The ideal pH level for growing rhubarb is about 5.5 to 6.5.
