Water Hyacinth Eichhornia
The water has to be warm, above 75 degrees
They need to be crowded together. You can make a ring out of tubing
to confine them
Koi love to eat the roots so keep them separate from the fish. Once
they eat the roots the plant goes down hill.
Remove them from the pond periodically and dip them up and down in a
bucket of clean water to release all the crud they collect.
If they become yellow, remove them from the pond and soak them over
night in a bucket of water that has water soluble fertilizer added
The soft plants and roots make for a great place for the fish to
Water hyacinths love moving water
They are hardy to zone 8. In lesser zones you can over winter them
in a suitable container in front of a sunny window.
This plant is illegal in AL, AR, AZ, CA, FL, LA, SC, and TX and can
not be shipped to those states!
