Water Plants in Containers
Start with any watertight container—a decorative pot, galvanized bucket or can, trough, or whiskey barrel. When using a planting pot, plug drainage holes. With a wooden container, attach a pond liner to the inside before adding water.
Larger containers hold greater water volumes, which provide more insulation against fluctuations in water temperature. Fish can’t tolerate extreme temperature changes. You need at least 20 gallons of water to support goldfish.
