Types of aquatic plants

Aquatic plants fall into four sub-categories depending on where in the pond they should be planted.

  • Bog plants – suited to damp areas to the outer ground of a pond
  • Floating plants such as waterlilies give cover to spawning fish and aquatic insects.
  • Marginal plants are planted on shelves around the outer periphery of a pond. They are perfect for natural or wildlife ponds providing much needed cover. Popular choices include the Arum Lily, Iris, Lobella and Cyperus (Paper Reed Papyrus). For some marginal aquatic plants the depth of water they are grown in is very important, so read labels and check the requirements before buying.

Try to have a mix as well as variety of floating and submerged plants that suit your pond size.  When positioning aquatic plants in your pond it is best not to use a garden fork or stick to aid your planting as you may inadvertantly touch the bottom of your pond and damage the pond liner.

Protecting the pond liner from damage should always be considered when placing plants in your pond.

One further tip is to ensure the plants you buy are healthy and free of pests or disease. It is advisable to rinse them off under clean water before adding to your pond.
