Overwinter Water Plants  One year I left my water hyacinths in
our pond over winter and they froze. What should I do to keep
them alive? I'm also trying to overwinter water lettuce and
duckweed.  —Barbara Ray, Vidalia, Georgia  Melinda: Many common
water plants, including water hyacinths, water lettuce and some
species of duckweed, are tropical. They can't survive winter
outdoors except in regions where the water stays quite warm. In
those areas, these plants flourish so well they sometimes become
weeds and should be used only in contained ponds. To overwinter
these plants in other areas, place them in an indoor aquarium.
Make sure the water is warm and filtered, and use artificial
lights to supplement or replace natural sunlight. Then move the
plants back outside in spring once air and water temperatures
are consistently warm.  Follow us  facebook twitter Pinterest
