Here along the Gulf Coast, waterlilies are repotted annually, starting in April. Otherwise, they become crowded and will not bloom as frequently. Remember to use clay-based topsoil to repot. (Do not use commercial potting mixes)
Starting 2 months after repotting, fertilize with 2 Pondtabbs per 7qts. every two weeks until October.
- Wash all soil off the lily roots. Hardy waterlilies produce long fleshy roots called rhizomes, these can be cut when repotting.
- The part of the root where the leaves emerge is called the growing tip. Cut the rhizome 4-5 inches back from the growing tip.
- Use a 7 qt pot or larger without drainage holes. Fill 1/3 full with topsoil, sprinkle with 1 tbsp of Landon Fertilizer per 7 qts. of soil and mix thoroughly.
- Dig a shallow trench from the center of the pot to the side; next lay in the rhizome with the growing tip pointing toward the center.
- Fill with topsoil to within 1-2” of top.
- Firmly punch down the soil to eliminate any air pockets.
- Top off with a 1/2” layer of sand and then a 1/2”-1” layer of pea gravel.
- Gently lower the waterlily back into the pond.
