Here’s what you will need for your very own table-top water garden:
A glass container, bowl, wide-mouth vase etc.
Water plants such as taro, water lettuce, water hyacinth, duck weed, fairy moss etc.
Plastic pots shorter than the height of your glass vessel
Mosquito fish (optional)
Place the taro in your plastic pot and add soil. Pack the soil down snugly and cover with rocks and pebbles. Rinse off any loose soil from the exterior of the plastic pot. Make sure your bowl/vase/container is clean and free of cracks. Take a handful of charcoal and line the base of the vessel to help against odors. Cover with aquarium pebbles. Fill the vessel with the most pure water you can get your hands on; rain water, reverse osmosis water, or distilled. Place the potted taro into the vessel. Some loose soil may escape the pot- just scoop it off the top of the water, and add more rocks to the potted plant if needed. Pull off any dead roots from the floating water plants, and give them a good rinse before adding to the bowl. If you plan on taking the water garden outside, and then bringing it back inside later, mosquito fish are a good idea. Nobody wants mosquitoes hatching in their living room!
