Traditional aquatic baskets come in a wide range of sizes and shapes to suit every water feature and pond. There are two main types available: one with an open, wide mesh and ones with a fine, louvre-type mesh. The former have to be lined with material such as hessian or a woven polypropylene, these are permeable materials that will allow water and gases to move in and out but will prevent the compost escaping into the water. The louvre-type need no lining as the way the mesh is designed contains the compost.
In addition to these traditional containers there are also non-rigid, bag type ones which have floats, these can be used for marginals where shelves are not built into the pond. Also available are cubes of rockwool, in which the plant is already growing, these can simply be dropped straight into the pond.
