This year most of my hyacinth have satyed in the yellow rather than
green phase. And they have not grown as tall as usual. I tried
potash. It helped a few of them. The water celery is thriving.
Could this be an iron issue? Any suggestions as to a good source for
iron, if that is likely to be it? I have ironite that I use in the
garden, but I don't know if it would have bad effects for trace
minerals if used in the pond.

Suggestions?

Jim,
A couple of things.

That could be a nitrogen deficiency. Take a few of them and plop them in a
pail with some water and a high nitrogen fertilizer.

Could also be a ph issue. Different nutrients are drawn into different
plants between specific ph values. My ph is 8.5 and I rarely get the water
hyacinth to bloom and it doesn't look anywhere near as green as the water
celery.
