Water Gardening: My water lily just won't bloom, 1 by Carolyn22

Mine flower from May to early October. My waterlilies are potted - I cannot imagine not having them in pot. With pots, you have better control over your waterlilies. I would be afraid of the waterlilies taking over the whole bottom of my pond if they were not contained - I know they are not as prolific as the lotus, but I don't want to take the chance. Additionally, this would pose a problem when I vacuum my pond in the Spring and the Fall.

Waterlilies will need fertilizing every year - they are heavy feeders and division every couple of years - I divide every other year. I tried not fertilizing last year to see what would happen and I did not have nearly the same lilypad coverage or flowers. Cathy mentioned fertilizers high in nitrogen producing more leaves than flowers - she is correct. You want a higher middle number in your fertilizer formula to ensure more flowers.

Fish Knees is right - Waterlilites need SUN to flower - at least 6 hours of sun. Waterlilies will start flowering when your water temps are about 65 degrees. How much sunlight does your pond get?
