Divide your lily of the valley in the fall, after the plant has flowered. In autumn, the plant won't be expending so much energy on flowering, and can use those energy reserves to build out roots and leaves before the ground freezes. Water the plants a few days before dividing them, and trim them to about six inches above the ground. Then, use a spade or trowel to dig up the rhizomes of the plants, being careful not to cut them. Use a trowel or knife to cut the rhizomes apart, and, if necessary, use shears to trim your way through any dead or entangled roots.
Replant the rhizomes immediately, allowing six inches or so between each. Water them in well, and wait for the next springtime to enjoy even more lilies of the valley!
