Strategically placing plants around a garden pond accentuates your water feature. In nature, ponds and streams are framed by marginal plants. Marginal plants have extensive root systems that help stabilise the soil and prevent erosion. Create a bog garden around part of your pond that will support marginal plants and give your pond a natural appearance. If a bog garden seems like too much effort, there are many plants available that are attractive and low-maintenance and readily grow along the edge of garden ponds.
Dig a small depression at least 12-inches deep around the edge of your pond and cover it with the pond liner. Ensure that the soil berm is sufficient to separate the pond water from the bog garden to prevent soil from entering your main pond.
Line the bog garden with a soil mixture containing half peat moss and half sand. Fill with water to create a muddy substrate.
Plant marginal plants in the bog area: Papyrus, marsh marigold and pickerel weed are all excellent bog plants.
Water the bog weekly.
Plant ornamental grasses, herbs and evergreen shrubs in other areas around the pond to create depth, add colour and increase biodiversity.
