Plant Rhubarb in early spring.  Mix rich humus into soil.  Well drained soil preferred. Rhubarb will flourish in a pH range of 6.0-6.8. Space rows 5 feet apart. Cover the crowns with soil so that buds are 1-2 inches below the soil.  As soon as the first shoots emerge, mulch heavily with compost or leaves.  Remove seed stalks as soon as they appear.  Re-mulch in the fall and again the following spring.
