Trim Yellow Iris Regularly
If you happen to plant some Yellow Iris near or around (or even “in”) your pond, you should trim them regularly. Doing so will “encourage” growth and ensure that it consumes just the right amount of nutrients from the pond water and/or substrate/surrounding soil. If left untrimmed, the plant would consume excessive amounts of nutrients from the pond’s water but these nutrients may not be evenly-distributed among the plant’s parts because of the long, untrimmed stems.
