Now is the time (August/September) to repot and thin or divide hardy water lilies. A question we often get is how to cut and divide hardy rhizomes. So we have prepared this instructional video on the basics.
If you are repotting water lilies we do have our own water plant potting mix available ($14 for 25L bag). You should fertilize the lilies when replanting and around every 2 months during the growing season. Slow release fertilizer tablets and lily baskets are all available in store.
