Tips on Creating An Amazing Koi Garden

What's the first word that comes to mind when you think “garden”?  Plants?  Vegetables?  Flowers?  These are great gardens and rewarding hobbies for those who have a green thumb. 

But they pale in comparison to a Koi garden, which mixes the natural element of water with plant life and beautiful, shimmering fish of all colors of the rainbow.  A Koi garden is a thriving ecosystem and is beautiful to see in action.

Whether you already own a pond garden or you are specifically building one for Koi, there are several factors you’ll want to consider...

Depth and Size

The first thing to consider when building a pond for your Koi garden is depth and size. Koi need a water depth of at least four feet to give them protection from their natural predators – cats, raccoons, and other carnivorous wildlife. Remember that Koi can grow to several feet long and need significant space to thrive.

A healthy Koi pond contains at least 1000 gallons of water. If you plan on having lots of Koi (or even a few large Koi!), you will want the largest pond your space can accommodate.  If you can only fit a small pond, you have the option of having fewer Koi or giving away your larger fish. 

Location, Location, Location

Once size has been determined, you must find an appropriate location. Find an area that is out of direct sunlight. Koi thrive best in cooler water, so you do not want them getting overheated during the day. A place shaded by a tree is ideal for maintaining temperature as long as you don’t mind skimming the water to catch fallen debris. 

Being under a tree also protects Koi from being scooped up by birds of prey like hawks. Be careful to monitor your use of pesticides and lawn chemicals. These are deadly to Koi, even in tiny amounts.

Plant Life

Because Koi are opportunistic eaters (see Koi feeding), they generally do not co-exist well with plants. Koi like to “dig” into potted underwater plants, causing a mess of soil and plant debris. They will also nibble on the foliage.

However, it is possible to integrate plant life into your Koi garden! Some solutions that have worked for other Koi owners involve putting netting over the plants or weighing potted plants down with river stones.

You can also choose floating plants like water lilies, which come in many beautiful varieties. Find out which water lilies do best in your pond’s water depth. Lilies do not oxygenate the pond water, but they have the bonus of giving shady areas for Koi to relax.
