Day and night blooming- tropical waterlilies can be planted in an 8" or larger diameter pot (a smaller container will result in a smaller plant). Fill the pot 1/2 full with a regular garden soil (clay type is good) and add a fertilizer tablet, then continue to fill the pot to about 2 inches from the top.
The plant should be set upright with the roots buried gently in the soil. Make sure the growing tip of the water lily is not covered. Next, add an inch or two of pea gravel or sand in order to prevent the soil from escaping from the container.
Remember to keep the gravel or soil away from the crown or growing tip of the waterlily. The plant can now be lowered into the water to a depth of about 3 inches over the crown of the waterlily. As the plant grows, it can be lowered to a depth of 6 to 12 inches. Tropical waterlilies like full sun, at least 5 to 6 hours per day and can bloom all year in Hawaii. Time-release Aquatic-Tabs fertilizer tabs should be pushed into the soil away from the crown once a month.
