Once a Phoenix homeowner becomes a pond owner, they often receive gifts of free aquatic plants. This could be from plant exchanges through hobby clubs or simply gifts from well-meaning friends. And that’s great – as long as you know what you’re getting.
There are some plants that should NOT be added to a standard-sized living, liner ecosystem pond in Phoenix. We have had to charge clients thousands of dollars to repair damage caused by aggressive, invasive aquatic plants because they’ve taken over their pond, rooted through the liner, rooted into the equipment, and basically wreaked all kinds of havoc. We advise our clients to never add anything to their backyard pond that’s not specifically listed on our website on the Plants page as safe without first running it by us.
Here are a few plants that can potentially cost a Phoenix homeowner thousands of dollars to remove once established:
Umbrella Palm
This plant is super-happy with our Phoenix weather and high-alkali water! It’s an attractive plant that grows fast and strong, which is probably why people might choose it for their pond. It’s aggressive and has strong sharp roots, as well as leaves that will cut through even the toughest calloused skin, making it a nightmare to keep under control and/or remove.
Yellow Iris
This is not your typical Louisiana Iris that stays demure. This guy is a monster! If you’re going to use it, you must absolutely stay on top of keeping it thinned out because it will eat your pond.
Full-Size Cattail
While the dwarf variety is a wonderful backyard pond plant, stay away from full-size cattail. Like the Yellow Iris, it can get out of control quickly. It spreads by its roots and its fluffy seeds.
Pennywort
This little guy will go nuts and cover your entire pond in one season. And getting rid of it requires getting every single little hair root out, and staying on top of it the second another plant starts to form. Many people love this plant in their pond; just make sure to keep it under control through regular thinning practices.
Equisetum
Another large aggressive plant that doesn’t belong in a standard backyard pond. If you must have it, you can keep it in a pot, where you can control it.
Bamboo
Although you might think that bamboo and ponds just naturally go together, this one is a huge no-no. Its roots are super-sharp, travel underground where you don’t even see it happening, and will stab through even concrete, let alone liner.
So, if someone gives you an aquatic plant, thank them kindly, and then do your research before plopping it into your pond.
