the grapevines covering it created too much shade.

But in the big pond, approximately the size of an Olympic swimming pool, They
shrivelled up and died. I blamed that on residues of a herbicide, which somebody
had dumped into the water years earlier, until I learned, that Koi (we have them in


that pond) love to chew off the roots of water hyacinths.

Thus I suspect, that, since all the plants around it that pond do well, this expert has
probably missed the most obvious cause: fish in the pond. Since goldfish are also
members of the carp family, I presume the love for hyacinth roots goes for them as
well.

That is just to show, that you should be guided by experts, but do not trust them
completely.

These water hyacinths had their roots protected by large perforated pots,
kept afloat with a Styrofoam collar and set adrift in a pond with koi carp.

As you can see, they are doing well

Best,

Well this expert is probably not a Tropical Botanist
