      How to select plants suitable for a wetland filter?

      How can I go about selecting plants suitable for a wetland filter?

      I talked to some locals who are gardeners, and they say gardening is super challenging in my area, due to the climate (New Mexico). They suggest only planting native plants.

      The problem is, most native plants don't like water...the wetland filter has tons and tons of water.

      I did find a list of plants that are found in the Rio Grande River, probably to be planted underwater. Will these qualities make it suitable for a wetland filter? Do I need to fill the wetland filter with a deeper layer of water?

      Everything I've planted in the water eventually over spread their area and become
      invasive. I'd put each plant in a pot and pull it every year and be sure to remove
      any runners that have made it out of the pot.

      Look for plants called marginals or bog plants. There are plenty that should thrive in your climate. Cattails and Pickerel rush are two that I have. As long as the pot is slightly under water, they will grow. If you don't have them potted in your wetland, you are going to end up with a tangled mess all jumbled together. You might consider having a single species to avoid that problem. Then you can simply dig out some of them to thin. Cattails are especially good at removing nitrates. Pickerel rush blooms all summer with purple flowers. It grows really fast and is very invasive.

      Plant selection depends on climate and your size and concept details of a wetland filter. Most bog systems get too overgrown after several years. Even with occasional maintenance they get to the point where a big messy, difficult and time consuming clean up is needed.

      Can't beat the anoxic filter concept for a plant filter considering short and long term maintenance issues and time and labor needed. The anoxic system of a cleanable bottom and removable plant baskets that grow well results in a more easily maintained system.

      I never had a problem with my big filter and I used various types of plants. Just don’t neglect maintenance because it is doing well and is healthy. Every two or three years thin out your plants and replant or replant with a different plant for a different look. By replanting your plants do not get so thick or root heavy.
