Our hyacinths continue to move from yellow to green on the berm. In the
pond, the greening is much less. Additions: only iron.

We noted that some of our other plants were also yellowing. They too may be
short on iron.

The hyacinths in a tub of water with a little iron and a little fertilizer
have not changed noticeably, although there was a big algae bloom for a
couple of days. Not sure what to conclude from that. Maybe those hyacinth
were too far gone.

We added some tomato fertilizer last night. Will watch that for a few days
to see if there is a significant change.

The ph is still 9, so that does not seem to preclude the greening.

Overall, it seems the iron was the issue.
