Scallion Water Tank Cultivation Method: One unique and visually appealing way to grow scallions is by using a water tank. This method allows the green leaves of the onion to thrive in a clean, bright environment. By August, the plants can reach over 30 centimeters in height. At this point, dozens of flower stems can be harvested, and by the end of September, beautiful white flowers will bloom. What makes this method special is that the flowers appear below the water surface, creating a stunning contrast against the clear water. The white blossoms stand out among the lush green onion foliage, resembling delicate orchids floating in the tank. The specific method involves preparing several glass fish tanks measuring 90 cm in length, 50 cm in height, and 35 cm in width. In early April, plant mature onion bulbs into small containers—such as 4- to 5-cm-long plastic bags or light porcelain pots—that are filled with soil. Place the bulbs at a spacing of 2 to 3 cm apart. To encourage root growth, gently crush the roots with clay, fill the soil up to the top of the bulb, and lightly press it down. Then cover the top with a 0.5-cm layer of coarse sand before placing pebbles between the bulbs to keep them stable. After planting, place the tank in a sink or pool and gently tilt it from side to side to wash away any floating dirt. Then, fill the tank with water up to about four-fifths of its height. For added visual interest, you can introduce a few small tropical fish into the tank. Not only does this enhance the aesthetic appeal, but it also creates a mini ecosystem that supports healthy plant growth. With proper care, your scallion water tank can become a beautiful and functional addition to your home or garden.
