At planting time, work in some humus, good garden compost or, even better, leafmould. Spread out any underground stems and cover with just a couple of inches of the planting mixture. Mulch well with leafmould. If you find that flowering is poor, an occasional dose of high-potash organic liquid feed may help… – See more at: How to Grow and Care for Lily of the Valley.
