Toad Lily 'Sinonome' plants must be in moist soil conditions at all times. Mulch around the plant's stem to hold the moisture for a long time. You should only need to add an inch layer on mulch and make sure you do not place the mulch layer too close to the stem. We recommend that you mulch about 1 to 2 inches away from the base of the plant so your plant can still breathe while it is retaining moisture.
