How to Winterize Water Hyacinth

While water hyacinth is an invasive plant in ponds and lakes, you can grow it in your water garden as long as it is container-bound. Water hyacinth are native to South America and float on the surface of the water, forming a thick canopy of foliage. The flowers of the water hyacinth are similar to true hyacinth blooms. Water hyacinth is only hardy in U.S. Department of Agriculture zones 8 to 11, so it needs special winter protection in most of the U.S.

     Place the container in a large tub. Fill the tub with water.

     Place the tub in a location where the temperature won't drop below 10 degrees Fahrenheit. A garage is a good location for the water hyacinth. Change the water in the tub every week to prevent disease.
