The reason for this is the roots and underground rhizomes will suffocate during the heavy rainfall periods of spring, summer or fall. Prior to planting in the spring, the soil should be well-fertilized and limed. The pH should be approximately 6.2 to 6.5 with fertilizer applied and mixed in. Planting is done by using young pieces of crown containing good strong buds. Older crowns should be separated and the outer portions planted.
Planting is done after the ground has thawed and can be worked properly.
The crowns are set deep enough so that the top of the crown is covered with about two inches of soil. Crowns are set about two feet apart in rows that are 4 to 6 feet apart. Clean shallow cultivation should be continued through the growing season so that weeds are kept to a minimum. In the third and subsequent seasons, the harvest period can last from six to eight weeks. Normally this will break off at the junction and produce very little injury to the parent.
