Our aquatic soil is perfect for all pond plants including Water lilies and marginal pond plants and is harmless to all known pond life.  For some pond plants like Water lilies and Irises, which are heavy feeders requiring higher nutrient levels, we would recommend the addition of slow release fertiliser tablets at the beginning of the growing season.  You should never use ordinary compost in ponds as the nutrient levels will be far too high and exacerbate problems with algae, and it will not provide sufficient weight to anchor the plants and baskets in place.  However, if cost is an issue you could consider using garden subsoil as long as it is free of herbicides and pesticides.  Some people advocate planting just using gravel as a substrate, but as to whether this will be successful or not will probably depend on the chemistry and individual characteristics of a pond: if the plants are able to obtain sufficient nutrients from the water they may be ok, but if not their growth will be weak, flowering poor and foliage sparse.  They may also be more susceptible to disease, however many swimming ponds are successfully planted on this basis.

Aquatic soil has a lower nutrient level than other soils and composts this will help minimise algal growth
