Can Ginger Lily Be Grown in Water? Hydroponic Methods and Flowering Care Tips

Ginger lily flowers resemble butterflies and have a fresh, delicate fragrance that fills the air. Many gardening enthusiasts want to know: can ginger lily be grown in water? The answer is yes. Like most hydroponic plants, ginger lily can absolutely be grown in a hydroponic container with a planting basket to hold it. However, growing it in water requires more attention to method than growing it in soil; water changes, pruning and adding nutrient solution are all steps that require skill, otherwise the plant is prone to problems.

Four steps to growing ginger lily in water

Step one, removing from the pot: take the ginger lily out of the flower pot together with its root ball. Before removing it, you can tap lightly around the sides of the pot to loosen the soil from the pot walls, so the stems and leaves are less likely to be damaged during removal.

Step two, removing soil and disinfecting: rinse the soil off the roots with clean water, then soak them in a potassium permanganate or carbendazim solution to disinfect and sterilise. This way, excessive microorganisms are less likely to breed after growing in water, and pests and diseases can also be reduced.

Step three, planting: place the plant into the planting basket, fix the roots in place with vermiculite, then set the planting basket into the mouth of the hydroponic container and add water. The water level should cover two-thirds of the roots, ensuring one-third of the roots are exposed above the water surface, which effectively prevents root rot.

Step four, later care: when first grown in water, change the water once every 10 days; after the plant resumes growth, change it once every 3-5 days; add nutrient solution once every two water changes. During care, if any root rot is found, prune it away promptly.

To get ginger lily to flower, light and temperature are the key points

As for light, ginger lily grown in water must not be placed in a dark spot, and especially not in a room with no light that is also rather enclosed. Insufficient light not only slows growth and makes flowering difficult, but also causes the plant to wither quickly.

As for temperature, ginger lily needs an environment of 25-30 degrees to flower, and it is very difficult for it to bloom when the temperature is on the low side, so when growing it in water you must be sure to keep the temperature moderate. In winter, take care to keep it warm, and the water temperature when changing the water should be close to room temperature; do not use water that is too cold, otherwise the roots will be damaged by the cold.

Is ginger lily toxic? Can it be grown without worry?

As the saying goes, "every medicine has some toxicity." As a Chinese medicinal herb, ginger lily's rhizome and fruit can be used in medicine, with effects such as warming the middle and strengthening the stomach, releasing the exterior, dispelling wind and dispersing cold, and warming the meridians to relieve pain, so it unavoidably carries a certain medicinal toxicity. But this does not stop us from growing it as an ornamental plant. It should be noted that ginger lily's fragrance is so strong that it can easily cause discomfort in people prone to allergies; for people who are not allergic, its floral scent is strong but not cloying, fresh and pleasant, and it also has the effects of purifying the air, relieving fatigue and refreshing the mind, and repelling mosquitoes, so it can absolutely be grown without worry.

Finally, a little profile of ginger lily: scientific name Hedychium coronarium, also known as wild ginger lily, butterfly lily, and spiked ginger lily. Its underground stem is tuberous and grows horizontally, with its own fragrance, resembling ginger; the inflorescence is terminal and spicate, with each inflorescence bearing 10-15 flowers, and flower colours include white, yellow, red and orange. It likes light, tolerates partial shade, and is not cold-tolerant; it prefers a warm, humid climate and grows well in slightly acidic, fertile sandy loam; when the winter temperature drops below 10°C, the above-ground parts wither and the underground ginger tubers go dormant to overwinter. The flowering period is from May to November, and its flower language is trust, noble purity and elegance, and simplicity. Besides being grown in water for ornament, ginger lily is also suitable as a cut flower, or for mass planting beside roads, on lawns, by streams, beside ponds and next to rockeries.
