Water Lily Care 101: A Beginner's Guide to Growing and Maintaining Your Plants

Welcome to Jardín de Nenúfares! If you've recently added water lilies to your pond or are considering doing so, you’re in for a treat! Water lilies are among the most beautiful and rewarding aquatic plants to grow. With their stunning blooms and easy maintenance, they add elegance and tranquility to any water garden. However, like all plants, they require a little care to thrive. In this guide, we’ll walk you through everything you need to know about growing and maintaining healthy water lilies, from planting to fertilizing and managing pests.

1. Choosing the Right Water Lily for Your Pond

Before we dive into care tips, it’s important to choose the right water lily for your pond. Water lilies come in two main types: hardy and tropical.

• Hardy Water Lilies are perfect for colder climates and can survive winter dormancy. They are low-maintenance once established and bloom year after year.

• Tropical Water Lilies thrive in warmer climates, growing quickly with larger blooms in a wide range of vibrant colors. They do need to be brought inside or kept in a heated environment during the colder months if you live in a frost-prone area.

2. Planting Your Water Lilies

Planting your water lilies properly is essential for their success. Here’s how to do it:

• Choose a Container: Water lilies grow best in a container that’s placed in the pond, so choose a sturdy, non-toxic container (a plastic container or basket works well).

• Use Aquatic Soil: Fill the container with a nutrient-rich aquatic soil (do not use regular potting soil, as it can cause murky water). Gently pack the soil down, leaving enough space for the lily’s roots.

• Position the Rhizome: Place the rhizome (the root-like structure) horizontally in the soil with the growing tips facing upward unless it is a hardy (see our dedicated blog post on this topic) Be careful not to bury the growing tips.

• Submerge the Container: Once planted, slowly lower the container into the pond at a depth of 18–24 inches. You may need to adjust the depth as the plant grows, but water lilies should be submerged 3 to 6 inches below the water surface.

• 
  

Pro Tip: Ensure your pond has enough space for the lily’s growth. Most water lilies spread quite a bit and need room to thrive.

3. Providing the Right Amount of Sunlight

Water lilies need full sunlight to bloom. Aim for at least 6 hours of direct sunlight each day. Without enough sunlight, your water lilies may not bloom or thrive.

• If your pond is in a shaded area, consider trimming nearby trees or bushes to increase sunlight exposure.

• If you have a pond with variable sunlight, some varieties of water lilies may still do well, but they may bloom less frequently.

4. Water Conditions: pH, Temperature, and Quality

Water quality is crucial for healthy water lilies:

• pH: Water lilies prefer a slightly acidic to neutral pH, around 6.0–7.0.

• Temperature: Hardy water lilies can handle cooler water, while tropical varieties thrive in warmer water temperatures between 70–85°F (21–29°C).

• Water Clarity: Keep your pond water clear and clean to help your lilies grow. Dirty water can stunt growth and lead to algae blooms. Consider installing a pond filter if your pond tends to get murky.

5. Fertilizing Water Lilies

Water lilies require nutrients to grow and bloom, so regular fertilization is important. Here’s how to keep your lilies well-fed:

• When to Fertilize: Begin fertilizing in the spring as your lilies start to show new growth. Continue fertilizing until mid-summer. After that, you can reduce or stop fertilizing for the rest of the growing season.

• Type of Fertilizer: Use a slow-release aquatic fertilizer specifically designed for water plants. Fertilizer tablets or stakes work well as they dissolve slowly and provide a steady supply of nutrients.

• How to Apply: Insert the fertilizer tablets directly into the soil near the roots of the water lily. Be sure to follow the instructions on the fertilizer package to avoid over-fertilizing.

• 
  

6. Managing Pests and Diseases

Water lilies are relatively low-maintenance but can occasionally suffer from pests or diseases. Here’s how to address common problems:

• Snails and Insects: Snails, aphids, and other insects can sometimes damage the leaves of water lilies. If you notice holes or damage, try removing pests manually or using non-toxic insecticidal soap.

• Fungal Diseases: Water lilies can occasionally develop fungal infections, especially if the water quality is poor. If you see discolored or decaying leaves, remove them immediately to prevent the spread of disease.

• Algae: Algae growth in your pond can compete with water lilies for nutrients and sunlight. Regularly clean the pond and consider adding pond plants that naturally help reduce algae growth, such as submerged oxygenators or floating plants like water hyacinth.

7. Trimming and Deadheading Your Water Lilies

To keep your water lilies looking their best, regular maintenance is key:

• Remove Dead Leaves: As water lilies grow, older leaves will die off. Regularly remove any yellow or decaying leaves to keep the plant healthy and prevent water quality issues.

• Deadheading: After your water lily flowers bloom, remove the spent blooms. This helps redirect energy into producing new flowers.

8. Overwintering Water Lilies

If you live in a cold climate, you’ll need to take extra care during the winter months. Here’s how to overwinter your water lilies:

• Hardy Water Lilies: These can be left in the pond over winter. Simply cut back the leaves and allow the plant to go dormant. The rhizomes will survive the cold, and new growth will emerge in the spring.

• Tropical Water Lilies: Tropical lilies need to be brought indoors or kept in a heated area for the winter. You can either transplant them to a pot and bring them inside or move them to a heated greenhouse.

Final Thoughts

Caring for water lilies doesn’t have to be difficult—once they’re established, they’re relatively easy to maintain. By providing the right environment, planting them properly, and keeping up with regular care, your water lilies will thrive and provide beauty and tranquility to your pond for years to come.
