Aquatic Plants for Natural Swimming Ponds
By planting and growing the correct mixture of aquatic plants, a natural swimming pond will stay clean and clear. We prefer to use British native plants as much as possible and can create the best mix of planting to suit the colour palette and overall look that you prefer. Generally speaking, this means planting low height plants at the front the regeneration area, moving to taller more structural plants at the outside edge of the pond. Please see below for a selection of recommendations, presented in ascending height order.
