Water hyacinth

When should I bring in my water hyacinth?
I have about 20 something water hyacinth in my koi pond. I want to keep them for next season also. When should I bring them indoors? I live in maryland.  Also what can I do to make them grow great, like what nutrients should I add to their water? Is it safe to pluck their nast,y mushy stem and leaves, or should I leave them be? 


Answer:
Take off all the mushy stems and leaves before you bring them in. Add only a dechlorinator to the water inside. Since they need full sun to grow, they may well go dormant before next spring, but they will come back. Bring them in when the nights begin reaching temps of 55º at night.

If the water they are in gets too unbearable, pack them in damp sand and leave them in the garage.
