How to Use This Planner
Ponds are living, breathing ecosystems and no two are ever quite the same. Factors like sunlight, shade, water quality, rainfall and even nearby trees all play a role in how your pond develops over time. That’s why this calculator is designed as a guide to planting, not a strict rulebook.

You’ll find two helpful calculators below:

Pond Area Calculator uses your surface dimensions to estimate how many oxygenators, floating plants, waterlilies, and deep water plants you’ll need to create a balanced, healthy pond.

Marginal Shelf Calculator works differently, it’s based on a linear shelf measurement and tells you how many marginal plants to place along the pond edge.

Marginal Planting Tips - For the most natural effect, we always suggest clump planting. Buying three of each variety allows you to create attractive, bold groups that blend beautifully into your pond’s surroundings.

Try to leave a little space between plants too, this helps prevent overcrowding and gives each species room to thrive without one taking over.

Our recommendations follow best practice for stocking and is a great starting point for building your pond's plant life. From here, you can fine-tune your planting depending on your pond's shape, microclimate and wildlife goals.
