Understanding Water Lilies: Nature's Floating Masterpieces
Types of Water Lilies
Water lilies come in two main types, each with its own characteristics and care requirements:
Hardy Water Lilies:
Can survive cold winters, making them perfect for year-round outdoor ponds
Flowers float on the water's surface
Come in a range of colors including white, pink, yellow, and red
Leaves are typically round with a split from the edge to the center
Bloom during the day and close at night
Examples include 'Attraction' (red), 'Marliacea Chromatella' (yellow), and 'Gonnere' (white)
Tropical Water Lilies:
Need warm weather to survive, often treated as annuals in colder climates
Flowers stand above the water on strong stems
Come in a wider range of colors, including blue and purple
Leaves may be round or star-shaped, often with wavy or toothed edges
Can be day-blooming or night-blooming
Examples include 'Blue Beauty' (blue), 'Director George T. Moore' (purple), and 'Texas Dawn' (yellow)
Water Lily vs. Lotus: Clearing the Confusion
Many people confuse water lilies with lotus plants. While both are beautiful aquatic plants, they have some key differences:
Water Lilies:
Leaves and flowers float on the water's surface
Leaves have a distinct split from the edge to the center
Smaller flowers that typically close at night (except for night-blooming tropical varieties)
Prefer still water
Lotus:
Leaves and flowers stand well above the water on tall, strong stems
Leaves are completely round without a split
Larger flowers that remain open at night
Can tolerate some water movement
Choosing and Buying Water Lilies
Where to Buy
For the best selection and expert advice, it's recommended to buy water lilies from stores that specialize in pond plants. One Stop Garden Shop Co. (OSGS) offers a great variety of water lilies and can provide personalized recommendations based on your specific pond conditions.
Factors to Consider When Buying
Pond Size: Make sure the water lily variety you choose is appropriate for your pond's size. Some varieties can spread up to 6 feet in diameter, while dwarf varieties might only reach 1-2 feet.
Water Depth: Different water lily varieties thrive at different depths. Make sure your pond can accommodate the ideal depth for your chosen variety.
Sunlight: Most water lilies need at least 6 hours of direct sunlight each day to bloom well. Consider the sun exposure of your pond when selecting varieties.
Climate: If you live in a region with cold winters, hardy water lilies are your best bet for perennial growth. In warmer climates, you have more flexibility to grow tropical varieties year-round.
Color and Bloom Time: Choose colors that complement your garden design. Also, consider when the lilies bloom - day-blooming varieties are great for enjoying during the day, while night-blooming tropical varieties can add magic to evening garden parties.
Growth Rate: Some water lilies grow and spread faster than others. If you have a small pond, look for slower-growing or dwarf varieties.
When selecting a plant, look for these signs of health:
Leaves should be firm and green, without spots, holes, or discoloration
Roots should be firm and light in color, not soft or dark
There should be no signs of pests or disease, such as aphids or fuzzy mold growth
Planting Water Lilies
Proper planting is crucial for the health and growth of your water lilies. Here's what you'll need and how to do it:
Materials Needed
Aquatic planting basket (choose a size appropriate for your water lily variety)
Aquatic soil or heavy garden loam
Small rocks or pebbles for top dressing
Aquatic plant fertilizer tablets
Gardening gloves
Scissors or pruning shears
Step-by-Step Planting Guide
Start by filling your aquatic planting basket about 2/3 full with aquatic soil. If you're using garden loam, mix in some clay to help hold the soil together underwater.
Add aquatic plant fertilizer to the soil. Follow the package instructions for the amount to use based on your basket size.
Take your water lily and gently spread out its roots. If the roots are very long, you can trim them slightly, but be careful not to remove more than 1/3 of the root system.
Place the water lily in the soil at a 45-degree angle, with the growing tip pointing towards the center of the basket. The crown (where the leaves emerge) should be just above the soil surface.
carefully cover the roots with soil, pressing gently to remove air pockets. Leave the growing tip exposed.
Add a layer of small rocks or pebbles on top of the soil. This helps keep the soil in place and prevents fish from digging in the basket.
Slowly lower the basket into your pond. Start at the depth recommended for your variety (see next section), and gradually lower it over the next few weeks as the plant grows.
As you lower the basket, tilt it slightly to allow any air bubbles to escape from the soil.
Planting Depth and Positioning
The ideal planting depth varies depending on the type of water lily:
Hardy Water Lilies: Start at 12 inches below the water's surface, gradually lowering to 18-24 inches as the plant grows.
Tropical Water Lilies: Begin at 8 inches deep, eventually lowering to 12-18 inches.
For both types, the goal is to have the leaves floating on the surface while the pot remains hidden below.
When positioning your water lilies, keep these tips in mind:
Place them away from fountains or waterfalls, as they prefer still water.
Allow enough space between plants for growth - at least 3-4 feet for full-size varieties.
Consider the sun's path to ensure your lilies will receive enough light throughout the day.
Caring for Water Lilies
Daily and Seasonal Care
Proper care will ensure your water lilies thrive and produce beautiful blooms throughout the growing season.
Sunlight: Ensure your water lilies receive at least 6 hours of direct sunlight daily. If your pond is partially shaded, choose varieties that can tolerate less sun.
Fertilization: Feed your water lilies every 3-4 weeks during the growing season (typically spring through fall). Use fertilizer tablets specifically designed for aquatic plants, pressing them into the soil near the plant's roots.
Deadheading: Remove spent flowers regularly to encourage continued blooming. Cut the stem as close to the base as possible.
Leaf Management: Remove any yellowing or decaying leaves promptly to maintain water quality and plant health. Cut them off at the base of the stem.
Winter Care:
Hardy Water Lilies: In cold climates, lower the plants to the deepest part of the pond (below the freeze line) for winter. In spring, raise them back to their normal depth as new growth appears.
Tropical Water Lilies: In cold climates, these are usually treated as annuals. You can try overwintering them indoors in a bucket of water kept at about 50-60°F (10-15°C).
Division: Every 3-4 years, or when plants become overcrowded, divide your water lilies. Do this in spring just as new growth begins.
Pest and Disease Management
While generally robust, water lilies can sometimes face issues with pests and diseases. Here's how to identify and address common problems:
Aphids: These small insects cluster on leaves and stems. Rinse them off with a strong stream of water or use insecticidal soap if the infestation is severe.
Water Lily Beetles: These can severely damage leaves. Remove them by hand or use neem oil as a natural deterrent.
China Mark Moths: The caterpillars of these moths eat leaves, creating distinctive windowpane-like holes. Remove affected leaves and look for the caterpillars to remove them manually.
Leaf Spot Diseases: Fungal infections can cause spots on leaves. Remove affected leaves and improve air circulation around plants.
Crown Rot: This fungal disease causes the center of the plant to rot. It's often due to poor water quality or planting too deep. Remove affected plants entirely to prevent spread.
Regular monitoring is key to catching and addressing these issues early. Always remove any diseased plant material from the pond to prevent problems from spreading.
Water Lilies and Your Pond Ecosystem
Benefits of Water Lilies
Water lilies are more than just beautiful - they play several important roles in maintaining a healthy pond ecosystem:
Shade Provision: Their large leaves shade the water, helping to keep it cool and reduce algae growth.
Oxygenation: Like all aquatic plants, water lilies release oxygen into the water during photosynthesis, benefiting fish and other aquatic life.
Nutrient Absorption: They absorb excess nutrients from the water, helping to maintain water quality and prevent algae blooms.
Habitat Creation: Water lilies provide shelter and breeding grounds for fish, frogs, and beneficial insects.
Sediment Stabilization: Their root systems help stabilize bottom sediments, reducing water turbidity.
Potential Overgrowth and Management
While water lilies offer many benefits, some varieties can grow quite aggressively if not managed. To prevent overgrowth:
Choose appropriate varieties for your pond size.
Regularly divide plants that are outgrowing their space.
Remove excess growth promptly.
Consider using containers or barriers to limit spread in natural ponds.
Never dispose of excess water lily plants in natural waterways, as they can become invasive.
Safety Considerations
Keeping Your Pond Safe
While water lilies themselves are not dangerous, ponds can pose safety risks, especially for children and pets:
Install a fence around your pond if you have young children or pets.
Create shallow areas or stepping stones to allow for easy exit from the pond.
Always supervise children and pets around the pond.
Consider installing a pond safety grid just below the water's surface.
Water Lily Toxicity
Contrary to some misconceptions, water lilies are not toxic to humans or animals. However, it's generally best to discourage pets or children from eating any pond plants to avoid potential digestive upset.
Common Problems and Solutions
Even with the best care, you might encounter some challenges with your water lilies. Here are some common issues and how to address them:
Lack of Blooms:
Cause: Insufficient sunlight, inadequate fertilization, or improper planting depth.
Solution: Ensure plants receive at least 6 hours of direct sun daily, fertilize regularly, and adjust planting depth if necessary.
Yellowing Leaves:
Cause: Nutrient deficiency, improper water depth, or natural aging.
Solution: Check fertilization schedule, adjust plant depth, and remove old leaves as part of regular maintenance.
Floating Leaves:
Cause: Improper planting or fish disturbance.
Solution: Replant ensuring proper soil depth and adequate top layer of gravel.
Disappearing Plants:
Cause: Fish or animal predation, or aggressive snails.
Solution: Protect young plants with netting and control snail populations if necessary.
Stunted Growth:
Cause: Overcrowding or poor nutrition.
Solution: Divide crowded plants and ensure regular fertilization.
