🌿 Myriophyllum Spicatum (Spiked Water Milfoil) – Fast‑Growing Oxygenating Aquatic Plant for Clear, Healthy Pond Water

Myriophyllum Spicatum, or Spiked Water Milfoil, is a high‑performance oxygenating plant ideal for improving water clarity, supporting fish and wildlife, and creating a naturally balanced pond ecosystem. Its fine, red‑tinged foliage forms elegant underwater plumes that sway beautifully in the water, adding movement and texture to any pond or water garden.

Thriving in still or slow‑moving water, this submerged plant establishes quickly and grows vigorously, making it one of the most effective oxygenators for ponds of all sizes. Once settled, it can grow at depths of 30–100 cm, offering excellent coverage and oxygenation throughout the water column.

🌱 Key Benefits

• Improves Water Quality — Produces oxygen and helps maintain a healthy, balanced pond ecosystem.
• Rapid Growth — Quickly fills space and supports natural filtration.
• Attractive Foliage — Red‑tinged, feathery leaves arranged in whorls of four create a striking underwater display.
• Ideal Submerged Plant — Provides shelter for fish and fry while enhancing water clarity.
• Versatile Light Tolerance — Grows well in full sun to partial shade.

📏 Recommended Quantities by Pond Size

These guidelines ensure effective oxygenation and ecological balance:

• Small Pond (up to 2,000 litres / approx. 2m²)
  Recommended: 3–5 bunches
  Provides strong oxygenation without overwhelming the space.
• Medium Pond (2,000–10,000 litres / approx. 3–8m²)
  Recommended: 6–12 bunches
  Ensures good coverage and supports healthy water quality.
• Large Pond (10,000+ litres / 8m² and above)
  Recommended: 12–20+ bunches
  Larger ponds benefit from multiple planting zones for maximum effect.

These quantities can be adjusted depending on fish load, sunlight levels, and whether the pond is wildlife‑focused or ornamental.

🪴 Planting & Care Instructions

Plant 2–3 bunches per m² for optimal performance. Anchor the stems in soil or gravel for stronger establishment, or place as weighted bunches for easier installation. Begin in shallower water and allow the plant to naturally extend into deeper areas over time. Once established, it thrives at depths of 30–100 cm.
