How Do You Divide Water Lilies?
Cindy – Galesburg, IL
Dividing lilies may seem somewhat complicated, but our step-by-step process will explain exactly what you need to do. Try to plan it so you divide them during your spring cleanout, which would give easy access to tubers. Dividing is necessary every two to three years, and it is helpful if you notice the lily grew mostly pads and few lilies over the past season.
Step 1: Remove lilies from pond or container and rinse off. Plant baskets are ideal containers until they are ready to be moved to the pond.
Step 2: Trim away root growth and old foliage.
Step 3: Cut the tuber down to size. You can safely cut the tuber down between two to three inches on the growing part with a sharp knife. This can be increased to five to six inches on longer plants. Remember to also cut off new buds and older leaves, so that the new root system has a chance to grow.
Step 4: Plant each tuber separately or discard if you wish to reduce the lilies’ quantity in your pond. Use plant fertilizer and planting media for best results and a continuing healthy pond.
Step 5: Replant them shallow in the pond until new growth begins.
Step 6: Upon new growth lilies can be moved deeper into the pond.
