I Know That Floating Plants Help Shade My Pond, But What Do Submerged Plants Do? | Decorative Ponds & Water Gardens Q & A

I know that floating plants help shade my pond, but what do submerged plants do?

Q: I know that floating plants help shade my pond, but what do submerged plants do?

A: Got plants? If you’re like most pond hobbyists, you probably have plenty of growing and blooming greenery surrounding your water garden – but what about sub-surface varieties? Underwater plants, like hornwort, and red stemmed parrots feather, offer great benefits to your water feature and its inhabitants, including:

Filtration: Underwater plants naturally filter your water. How? Plants, with their copious amounts of surface area on their leaves, stems and roots, absorb nitrates and fish waste – which is actually fertilizer to them. The result is a body of water that’s cleaner and clearer, thanks to Mother Nature’s nitrogen cycle.

Predator Protection: Sub-surface plants also give your fish and other pond critters places to hide when predators stalk or attack. Koi and goldfish will swim into the lush growth and hide out when a raccoon stops by the pond or a blue heron circles overhead. The greenery provides excellent camouflage for your finned friends.

Aesthetic Appeal: As popular as they may be, gravel-bottom ponds are boring. And they’re not very natural-looking either. Have you ever seen a wild pond or lake with no plants beneath the surface? Nope, didn’t think so. Ponds planted with below-the-waterline foliage create a more realistic-looking – and aesthetically pleasing – water feature, which is something most (if not all!) hobbyists hope to achieve.

Oxygen: Underwater plants are called “oxygenators” for a reason. They naturally produce oxygen as a byproduct of photosynthesis – and oxygen is one of the best things for your pond’s health and vitality. When submerged plants are used in combination with a sub-surface aeration system, you’ll wind up with cleaner water that truly supports your pond’s inhabitants.

Spawning Areas: The leaves, stems and root systems of underwater plants give your pond life safe places to spawn and lay their eggs. And when those tiny fry hatch, the plants provide protection, food and a comfy place to call home.

Submerged plants are easy to add to your water garden or fish pond. Simply fill planting baskets, like the Laguna Submersible Pond Planting Baskets, with planting media, add some oxygenators, and place the planted basket on the bottom of your pond or on a plant shelf on the side of your pond. The planting baskets allow the plant’s roots to branch out and find nourishment while containing it and preventing fish from nibbling on its root system.

Add some plants to your pond today. Your fish will thank you for them!
