How Do I Preserve Water Hyacinths Over The Winter? - Knowledgebase Question

My Water Hyacinths grow great in 2 outdoor environments: 1) a 18"-deep dirt ditch that's fed water every day and 2) a dirt container in a 50 gallon goldfish pond with a waterfall pump that keeps water moving so the multiplying Hyacinth's roots gather food simultaneously clearing the water. Hyacinths are so expensive, I hate to have to buy new ones but I lose all my stock about every 3 years during the winter. The ones that survive best are always in the dirt ditch (my chickens watering source). How can I preserve at least 2 out of 20 - 30 plants until spring growing time starts? Bringing them indoors in a 5-gal bucket of dirt and water always fails but the same bucket outdoors sometimes is successful.

As you've discovered, the plants are quite tender and will die when temperatures dip too low. Water hyacinths can be wintered over in a bucket in a greenhouse where both water and air temperatures remain warm, or indoors in an aquarium where a source of light can help them retain their health. Good luck with your plants!
