Bog Plants Turning Yellow

[don't ask]

been taking in all the info plus what i can find online... my potted plants are doing fine, although lilies only bloomed once.. floaters look green and yellow and still haven't decided what the actual cause is making them yellow--from lack of nutrients, to fish nibbling on roots, to possibly too hot ...all of the above? man ponding can be frustrating

The only plants in my bog now are Forget-Me-Nots. They are all green now. Since I started this thread, I have opened the drain on the bog about 3 times and let it drain for about 3 minutes. Don't know if that helped or if they would of turned green anyway. Our weather has been up and down. Hardly any rain and the temp can be 20 degrees different from one day to the next. The Forget-Me-Nots are spreading nicely and filling in the spots where I tore out the Iris's.
The plants in the pond are doing great. No yellowing.

all part of ponding! figuring out what you should or should not worry about.
