What are marginal pond plants
As the name suggests, marginal plants are aquatic plants that thrive on the shallower margins of the pond, softening the edge of the pond while offering shade and shelter, reducing algae and improving the natural environment for wildlife.
What can I plant around the pond edge?
There are hundreds of great marginal pond plants, which can be subdivided into groups, including but not limited to:
- Pond rushes, grasses & reeds
- Irises for ponds
- Rafting pond plants
- Oxygenating marginal pond plants
- Caltha Water buttercups
- Low growing marginal pond plants
- Flowering Pond Plants
Where to position marginal pond plants?
Marginal pond plants can be planted either on the pond shelve to the maximum appropriate depth for variety. However a large number of marginal pond plants will also do well if planted in a bog/marsh garden where the soil is consistently damp. TIP: Always check plant advice label
Consider the maximum height your marginal plants may grow before positioning. Place the taller plants, including grasses, irises and rushes, at the back of the pond. In contrast, keep the rafting and lower growing pond plants at the front of your pond.
How deep should marginal pond plants be?
Marginal plants generally sit in the shallower edges of the pond. Different plant varieties can tolerate varying depths. Check each plant requirements before choosing its final depth and position.
How to plant marginal pond plants?
Marginal pond plants usually sit on planting shelves around the pond's edge. Most pond plants are sold as immature plants and will rapidly outgrow the supplied container.
We recommend replanting your pond plants into a good-sized pond planting basket for best results. Additionally, tall pond plants such as water iris or bull rush are particularly prone to be blown over, and using a sizeable aquatic basket will help counterbalance these plants.
Spreading and rafting plants can be planted into shallower baskets, but remember, they will need plenty of room for growth. Hence, it is always worthwhile replanting regularly to ensure the best possible display.
It may be possible in natural wildlife to plant directly into a pre-made planting area (See Edging a pond)
