Growing Lily Roots

Lilies are primarily available from nurseries as seedlings, which typically are comprised mostly of roots. Growing lilies from seed is much more difficult, which is why nurseries mostly stock the germinated lily roots. Lily roots are quite easy to grow, and the hardy varieties are rather self-sufficient plants that are tolerant of a variety of conditions. Lily roots are first transplanted into potting containers before being submerged in a water feature, pond or water garden.

Instructions

    • 1

      Line as many 10-inch potting containers as you have lily roots with burlap, leaving the edges hanging over the sides of the containers for about 3 to 4 inches.

    • 2

      Fill the containers with soil from the garden. Do not be tempted to use potting mix, as it is too light to be submerged and will float and cloud up the water where your lilies are placed. Mix in aquatic fertilizer pellets, around five or six into each pot.

    • 3

      Trim off with pruning shears any dead leaves or very thick and woody roots from your lily root stock.

    • 4

      Dig a hole large enough for the roots and the main tuber-like root of the lily to fit into, right at the edge of the pot. Plant the lily root into the hole, angling the end of the root and tuber toward the center of the potting container. This will help the lily roots to grow evenly in the pot.

    • 5

      Fold the edges of the burlap back over the top of the soil before covering the entire top with pebbles, which will help weight the burlap and soil down.

    • 6

      Dampen the containers with water so that all the soil is wet. Slowly lower the pots into the water where you want them to grow. A little clouding of the water is to be expected, but this will settle down. The lilies will likely be totally submerged at this point, but as they send up new shoots, you will see numerous lily pads emerge within a couple of weeks.
