Marginals25th October 2019 | Planting Advice
Marginals have a purely ornamental role as they do not play a part in maintaining the balance of a pond. Marginal plants are those that grow around outer edges of the pond where the water is shallow or in damp soil at the edge of the pond. Marginals help to disguise the edges of the pond but you should plan them the way you would any border in the garden as they provide floral colour and/or interesting foliage.
Marginals plants prefer to have their roots and crown (where the stems join the roots) wet, the recommended planting depth is 0-6 inches depending on the variety. The traditional method of growing them is to plant them on or in the shallows of the pond, you can also set them in baskets lined with hessian.
