When to Plant Water Hawthorn

Water hawthorn, also known as Aponogeton distachyos or cape pondweed, is an aquatic plant that produces delicate white flowers and is commonly used in outdoor ponds and water features. If you’re considering planting water hawthorn in your water garden, it’s important to understand the ideal planting time to ensure the plant thrives.

Planting Time

The best time to plant water hawthorn is in the spring, typically between March and May. This is when the water has warmed up to around 50-60°F (10-15°C), which allows the roots to settle and establish before the summer heat arrives.

Planting water hawthorn in the fall is also an option, but it’s important to do so at least six weeks before the first deep freeze to give the plant enough time to establish roots. Additionally, water hawthorn may not produce flowers if planted too late in the fall.

Planting Process

Before planting water hawthorn, make sure your pond is deep enough to accommodate the plant. Water hawthorn prefers a depth of at least 18 inches (45cm) but can tolerate much deeper water as well.

To plant the water hawthorn, use a planting basket with a fine mesh to allow the roots to grow through. Cut back any dead or damaged leaves and roots, and gently place the plant in the basket. Cover the roots with washed gravel or aquatic planting soil, and gently lower the basket into the water to the desired depth.

Once the water hawthorn is planted, make sure it receives adequate sunlight at least six hours a day, and use an aquatic fertilizer to promote growth and development.

Care and Maintenance

Water hawthorn requires relatively low maintenance compared to other aquatic plants, but it’s important to keep it healthy to promote growth and prevent disease. Some tips for caring for water hawthorn include:

Trimming underwater leaves regularly

Removing any dead or damaged leaves and roots

Checking for pests and diseases regularly

Maintaining a consistent temperature and water quality

If cared for properly, water hawthorn can thrive in a water garden and produce beautiful and delicate flowers. Remember to plant at the right time, provide adequate care, and enjoy the beauty of this aquatic plant in your outdoor space.
