Using the Best Plants for Koi Ponds has various benefits as it enhances the look of any landscape. Each pond needs a variety of the following shade and shelter-giving plants as part of their maintenance and upkeep. The addition of certain plants for filtration and oxygenation is also highly recommended.
This is because these beneficial additions will help the pond’s ecology. You can also stop algae growth by covering half of the pond’s surface with floating leafy plants. However, before deciding which ones best suits your display, it is advisable to look into the ones that koi won’t eat. The eye-catching umbrella plant, the large-leaved lotus plant, the water poppy with yellow flowers, and the floating water lettuce are some great suggestions.
However, an overpopulation of aquatic plants can stress a pond’s environment and perhaps harm the fish. Plants create oxygen throughout the day and raise the pH of the water but they also respire, taking oxygen and adding carbon dioxide, which lowers this level. Therefore choosing the best one for your pond is vital. Let us help you make the best choices with our suggestions below!

Aquatic Plants for Koi Pond – Best Picks
Aquatic plants can enhance a koi pond’s aesthetic appeal and environmental quality. The nitrogen that fish make from their diet is used by plants to produce oxygen for the water. These beneficial plants also shield the fish from predators and offer an abundance of shade. While floating plants for koi pond are highly recommended, there are others that you should also consider.
Consider the options below before adding any to your water feature.
1. Koi Pond Floating Plants
Due to the fact that they only sit on a pond’s surface, these plants are frequently referred to as floating plants. Although they can dominate a pond if not controlled, they offer shade to the fish and aid in keeping the water cool in the summer.
However, keep in mind that a koi pond shouldn’t have more than a third of its surface covered because a higher plant density could deplete the oxygen. Examples of surface plants that thrive in this instance include water clover, water fern, and water shield varieties.
2. Koi Pond Emergent Plants
Emergent plants float or stand above the water’s surface with strongly rooted stems below. They are commonly found in bogs and should be potted in containers and covered in pebbles because koi like to eat the roots of these plants.
Even though the fish will continue to consume some of the leaves, this should not harm this species of plant as long as a third of it is still above the water’s surface. The American lotus, cattails, and water lily are amongst the most commonly used for this purpose.
3. Koi Pond Submerged Plants
The term submerged plants refers to any plant that grows entirely underwater. Through their leaves, they take up the nutrients they require to thrive. Submerged vegetation filters the water while simultaneously supplying it with oxygen.
As a result of their competition with algae for nutrients, the growth of the latter is regulated. The varieties that fall under this category include water smartweed and the commonly known waterweed amongst others.
Koi Pond Care
The easiest technique to add plants to a pond is by using several types at once. Koi pond care is vital if you want to keep it in proper shape because you would find that some owners are unsure about whether or not they ought to have vegetation. For this curious fish species, new plants are novelties and are immediately consumed or knocked down.
This is less of an issue when introducing koi to an existing pond that already has a lot of plants in it, but it might be difficult when adding plants to an established koi pond that has few plants. Giving the pond an attractive appearance would require a little maintenance. Here are a few tips to keep your water feature looking its best!
Make sure the aquatic fertilizer is safe for fish before adding it.
The addition of salt to the water is a typical treatment for sick koi. Your plants will perish if you do this. Instead, remove the sick fish and isolate them before returning them to the pond as it is the safest way.
Emergent and surface plants compete with the algae for nutrients, which helps to keep its advancement under control.
To give the koi shade and keep the water cold enough in the summer around 70% of its surface should be covered by plants.
Larger ponds require fewer plants since the depth of the water keeps the koi cooler and offers shade.

Koi and plants can coexist if a few basic safety measures are taken. Put a lot of plants in the pond to spread out the fish’s curiosity, and cover roots and tubers with pebbles to protect them.

For this reason, ensure that you do not add any dangerous plants to your pond. Water gardens are not suitable for all plants.
