Ponds have a tendency to ‘green up’ with algae, especially if sited in full sun. Including plants can give clearer water and, if you’ve got fish, help supply more oxygen for them.
When choosing plants for the pond you first need to establish if you’re going to put fish in it or not.
If you do decide to have fish, make sure to section off new plants until they’ve grown new roots. This is because fish have a tendency to eat plant roots.
Pond plants are classified into five main groups: moisture loving, marginal, oxygenators, deep-water and floating. It’s possible to have plants from all these groups growing in the same pond.
