A koi pond garden delights everyone who experiences it.
Whether you are adding koi to an existing outdoor pond garden or creating a garden specifically for koi, there are several important factors to consider. A koi garden brings together three main elements: the pond, the fish and plant life.
Give koi room to thrive
The size and depth of the pond matter greatly. A pond at least four feet deep gives koi enough room to thrive and provides additional protection from predators such as cats and raccoons.
Koi can grow large, which is another reason to allow enough space. A larger pond also gives you the option to add more koi as your confidence in caring for the garden grows.
Choose the right location
Once you know the size of your pond, consider its position carefully. A location out of direct sunlight is usually best. Tree shade can help limit the view from flying predators, but it can also mean leaves and debris falling into the water.
Keep the pond away from pesticides and other harmful chemicals. Even small amounts of common lawn chemicals can be dangerous to koi.
Balancing koi and plants
Koi and plants can be challenging companions, but you can still enjoy planting around and within a pond. Koi may dig in potted plant soil, knock pots over, or forage on foliage, which can make a pond messy and create extra work.
Place netting over the top of plant pots to stop fish from digging, or cover the surface with pea gravel followed by larger river stones. This helps protect the pots from curious koi.
Use lilies for shade and shelter
Lilies are a lovely choice for a koi garden, with varieties suited to shallow and deeper ponds. Although they are not generally considered oxygenating plants, they provide useful shade and shelter for koi.
When you design the koi garden as a whole — rather than concentrating only on plants or fish — you create a space that can remain beautiful and thrive for many years.
