Too much sun for WH

I notice that the water hyacinth in my main pond is not nearly as
green as those in a smaller pool that is in my waterfall stream. The
pool hyacinths are deep green and are even flowering while the main
pond hyacinths are lime green - yellow.

The pool is partly shaded by some grasses nearby but the main pond
gets full sun.

Is it possible that WH wants only partial sun?

TIA

Take some of them out to a tub of water and Miracle Grow for a two
week vacation. This year I bought water lettuce and yesterday it
escaped the hula hoop I kept it correled in. Hyacinths like to be
crowded together too. happy water gardening.

Hi,
Water hyacinth will grow in FULL sun. Is there any chance that the roots are
touching bottom in the smaller pond?
They do grow better with the roots 'dragging' in the mud.
HTH -_- how
no NEWS is good

My theory: In sun the metabolism of the WH is so high it quickly eats
everything and starts to starve/yellow. ~ jan

That seems to be the case. Our pond is in part shade, water hyacinths were
always lush. Mom's pond is in full sun, they don't even seem to grow!

Disregarding nutrient limitations, most plants
exhibit some level of apparent greater growth under shaded conditions.
Waterhyacinth is one of those plants. Under full sun, plants produce
growth regulating hormones that result in compact, high density stem
and leaf growth. When shaded, less of the hormones are produced and
plants tend to elongate, attaining greater stem lengths, etc (but
usually lower biomass than those plants under full sun). "Leggy"
growth of plants is often the result of full sun species kept under
shaded conditions. Three and four foot tall waterhycainths are not
uncommon in the backs of shaded coves in some lakes.


An interesting example is seen in house plants. Most of us have noted
that some house plants tend to grow towards light (a window). This
occurs because the cells on the opposite side from the window grow
(elongate, not multiply) at a greater rate than those on the lighted
(window) side. The differential growth is caused by different growth
hormone concentrations produced in response to variable light
intensity on either side of the plant. The result is stems bending
towards brighter light.

Could depend what state you are in. In the south west it gets too hot and
the plants burn. Which doesn't hurt, since most of the states where they
would winter over if babied, they have been banned. I have been told that is
why my water lettuce yellows , it is burning faster than it can re-hydrate
it's self. At least that is the story I get. KathyAZ

Yellowing leaves are not a symptom of (heat or sun) burning. They are
a sign of nutrient deficiency or aging.

Ours yellowed for the first time this year. It turned out to be lack of
iron. We checked a variety of factors. HOWEVER, where the koi ate the
roots, the plants did not come back to green. Previously they have. The
pond hyacinths are yellow green. The smaller died. The ones in the berm
with the muck and no koi have darkened and are multiplying again. Our other
plants also yellowed and re-greened with iron. In our case, it was years of
growth without iron-replacement therapy.
