How to Create an Island for Your Fish Pond
An island is a place to have more plants in a fish pond. (Jupiterimages/ Images)

A little island in the middle of your fish pond adds interest and is a place to grow a few extra ornamental plants. Generally, you include the island when digging the pond, but you can also add a simple floating island to small, established ponds. You simply need to ensure that the island is secure and won't collapse within a week. You also need to avoid using any toxic substances or stressing your fish during installation.

  1. 1

    Select enough large, relatively flat pieces of lumber to cover the area the size of your planned island. Arrange them parallel to each other and bolt together to form a square.

  2. 2

    Attach a few wooden slats to the top with nails, leaving narrow gaps between them for plant roots.

  3. 3

    Attach the plastic drums to the underside of the raft with wire.

  4. 4

    Hold everything together more securely by tacking wire netting into place over the entire island.

  5. 5

    Attach a chain to the underneath of diagonally opposite corners.

  6. 6

    Float the island and attach the other end of the chain to a large, heavy rock to secure the island in the middle of your pond. Otherwise it is liable to drift to one side. A bit of leeway on the chain lets your island move around a little; securing it very tightly keeps it anchored in one place.

  7. 7

    Add gravel until the top of the island is a few inches above the surface of the pond. If you want decorations such as sculpture or rocks, put them on first, then add gravel to lower the island.

  8. 8

    Add garden soil on top.

  9. 9

    Add emergent plants to the island. Wetland plants suited to very watery habitats on the edges of ponds also grow well on pond islands.
