Our retention pond in our neighborhood has a lot of algae and problematic plant growth due to the surrounding farms and lawn runoff, so we're experimenting with a floating island to pull nutrients out before they can cause problems. This will also provide some interesting flowering plants, and more fish habitats.
Will be an interesting experiment to see what survives and what does poorly.
Zinnias, sunflowers, marigolds, and a few others are in net pots, inserted into cutouts in EVA foam mats.

Very interesting project, I'm curious if this one ends up being more cost effective at scale due to the difference in planting styles.
