Growing water lilies can be a very rewarding experience, creating a serene and beautiful focal point in a pond or water feature. Waterlilies are broadly categorized into two types: hardy and tropical. Their care is similar in many respects, but there are key differences, especially when it comes to overwintering.
Here's a comprehensive care guide that covers the general needs of most waterlilies:
1. Sunlight
Full sun is essential. Waterlilies need at least 6 hours of direct sunlight per day to thrive and produce abundant blooms.
Inadequate sunlight will result in fewer flowers and smaller leaves.
2. Water
Still or slow-moving water. Waterlilies do not like constantly moving or splashing water. Keep them away from fountains, waterfalls, or aerators. Gently moving water is generally not a problem.
Water depth: The ideal depth for most waterlilies is around 18-24 inches (45-60 cm) from the top of the pot to the water's surface. Miniature varieties may only need 6-12 inches (15-30 cm).
For new plants, start them in shallower water and gradually lower them as the leaves grow and reach the surface.
3. Soil and Planting
Use heavy, clay-based loam soil. Avoid standard potting mixes, which are too light and contain materials like perlite and peat that will float and contaminate your pond.
Aquatic planting baskets or containers are a must. They prevent the plant's roots from spreading uncontrollably and make maintenance easier. A container at least 14 inches in diameter is a good starting point.
Planting: Place the rhizome (the main root) at a 45-degree angle against the side of the container, with the growing tip pointing towards the center and slightly above the soil surface.
Cover with gravel: Add a layer of pea gravel or small pebbles on top of the soil to keep it in the pot and deter fish from digging.
4. Fertilizing
Waterlilies are heavy feeders. They require regular fertilization to produce many flowers.
Use specialized slow-release aquatic fertilizer tablets.
Push the tablets deep into the soil near the roots every 4-6 weeks during the growing season (spring through early fall).
Do not use liquid fertilizer in the water, as it can promote algae growth and harm fish.
5. Maintenance
Remove dead leaves and spent flowers. Regularly trim away any yellowing or decaying leaves and flowers that have finished blooming. This encourages new growth and keeps your pond clean.
Repotting and dividing: Waterlilies should be repotted every 2-3 years in the spring. This is also the best time to divide the plant if it has become too crowded. Remove the plant from the pot, trim back the roots, and cut the rhizome into sections, ensuring each section has a growing tip.
Pests: The most common pests are aphids. You can often remove them by simply spraying the leaves with a strong jet of water.
Hardy vs. Tropical Waterlilies: Key Differences
Hardy Waterlilies
Overwintering: Hardy waterlilies are resilient and can survive cold winters. As long as their roots (rhizomes) are below the freezing line in your pond, they will go dormant and regrow in the spring.
Bloom: Their blooms are typically held at or just above the water's surface.
Leaves: Leaves are often round with a V-notch.
Tropical Waterlilies
Water Temperature: These require warmer water. They will not survive if the water temperature drops below 60°F (15°C).
Overwintering: In colder climates (outside of USDA zones 10-11), tropical waterlilies are often treated as annuals or must be brought indoors for the winter. You can remove the rhizome from the pot, clean it, and store it in a cool, dark, and slightly moist place until spring.
Bloom: Tropical waterlilies often have larger, more fragrant flowers that are held well above the water's surface. They can also include blue, purple, and night-blooming varieties.
Leaves: Leaves are often serrated or have ruffled edges.
