I also have found that hyacinth like to be crowed. If they are just
floating in the pond that is sometimes a problem. In the wild they will
root into the edge of the water and grow out from there.
If you take one or two of the larger ones and stick them into a pot, no dirt
needed just rocks at the bottom to anchor, and then let the babies grow from
that, they do well. My sister lives in Michigan and her weather has not
been really warm this summer and hers are still green. This way too you can
tuck a pondtab into the pot.

Hi Tim,

We have not had a problem before this year. It may be that our koi were
happy with their catfish food and have a little less this year.
Previously,
they nibbled, but did not savage them as this year. We may need to swap
them around. In previous years, we have had a lot of smaller WH in the
pond. This year, we moved a smaller number of 18" hyacinth into the pond.

Jim

I also notice that my WH are much happier in the VF, much greener and
with
much longer roots than those in the pond where they are viciously
nibbled
at! I switch the yellower, anemic-looking ones in the pond to the VF,
and
the ones in the VF to the pond for a while...

Hi BV,

We wondered if that could be the case...however, we keep feeding the
koi
and
goldfish and it seems unlikely they would starve with respect to koi
waste
food. HOWEVER, the iron has made a difference.

The berm WH are returning to their dark green selves and have
begun
to
send out daughter plants...normally this happens at a wild rate. With
the
yellowing, it essentially stopped.

The (munched-root) WH in the pond are a LOT behind, but some are
getting
green streaks in the leaves...a first step.

The munched ones we floated in the tomato fertilizer (low
nitrogen)
are
slowly greening, about like the ones in the pond.

I infer the yellowing problem was indeed iron as that alone has
changed
the
WH in the berm. I infer the secondary problem for the pond WH is
eaten
roots.

With respect to starving, I infer we did starve them of iron. Regular
potash additions seem to have handled that aspect of things.

Thanks for wrestling with our problem with us.

I am delighted that the pf is doing well for you. Until the
yellowing,
I
used to cut over a foot a week from the pf in ur u-shaped falls and
the
two
barrels with it on top.

Jim

Jan,

Thanks for the suggestions.

I will give that a try. One new container with tap water coming
up!

The ones on the berm are progressively darkening.

Jim, you and Phyllis have a pretty seriously stocked VF, could you
simply
be
starving the plants? BTW, the PF you sent me, is taking over the VF.
Literally TAKING OVER. It looks awesome.

BV.
