Plants may be included in the backyard pond in a
number of ways. The most common method for most non-floating plants is
to pot them up and set the pot in the pond. Some people put soil in
pockets in the liner that allow the plants to take root and survive in
the pond.
Pots in the Pond - With
the advent of flexible liners for backyard ponds, there was a
transition from soil bottoms. So, people began putting more plants
into containers which are placed on shelves at different levels in the
pond.
Water lilies, lotus and many other plants like to have their roots
in soil rather than having them just float freely in the water. The
roots and rhizomes of such plants need to be placed in containers
before being positioned in the pond. Containers allow you to place the
pots at the correct depth and to move them for a change of pace or for
winter storage.
