Theoretically, a bucket of pond water with some Hyacinths in
willoverwinter in
the greenhouse/garage/shed as long as it doesn't gettoo hot/cold. They
can
then be returned to the pond after the last
frost of the spring.
Glad to
see
you wrote the word theoretically....because in all my ponding years I have
never known anyone in zone 7 or colder to sucessfully winter any over.
Even
with grow lights and the whole bit Jerri

I live near Denver (zone 5A?) and the winter before last I was able to
keep Water Hyacinths in our porch/green house area. I kept them in
a very large plastic tub in the window. The temperature in the porch
varied between about 45F and 70F. I added fertilizer about every
two or three weeks. They grew very well and I had to throw some out
during the winter because they grew during the late winter and spring.

This past winter, that plastic tub was used for something else and I put
them in a smaller tub. I also put some anarchis (sp?) in there and they
overwhelmed the water hyacinths. I also didn't remember to fertilize
them as often. This time they did not survive.

So it isn't quite as easy as just putting them in a bucket of pond water.
It does take some effort. Hopefully I will repeat the first year results
this
next year.
