What issues should be noted in hydroponic flower cultivation

Hydroponic flowers are also a form of soilless cultivation. They have many advantages, such as being clean and hygienic, requiring no watering, having roots clearly visible, and being able to form beautiful and charming shapes with the plant. Among foliage plants, many can be grown in water, such as Guangdong evergreen (Aglaonema), dragon tree (Dracaena), foliage begonia, clearweed (Pilea), pittosporum, inch plant (Tradescantia zebrina), and wax begonia. The following points should be noted with hydroponic flowers:

(1) Soaking cuttings to root. Cuttings should be 8-12 cm long and contain 3-4 stem nodes, and the cut surface of the cutting should be smooth and slanted. The cuttings and bottles should be disinfected with alcohol.

(2) Change the clean water once every 2 days. At 20-30°C, roots will form in half a month. During the rooting period, it is best to cover the cuttings with a plastic bag to maintain humidity, and place them in a semi-shaded spot indoors. After rooting, the water should not be changed, to prevent damaging the roots; when the water runs low, refill it promptly.

(3) The roots can grow as much as the bottle allows, but roots grown in water are relatively thin and weak.

(4) Bottle-grown water culture also requires fertilizing. During the growing season, apply a small dose of foliage flower fertilizer once every 2 weeks, which can promote robust plant growth.

(5) If the container used is transparent, it is best not to place it in direct sunlight, to avoid the water temperature rising and algae growing, which would affect root growth.

Hydroponic flowers are different from the plants that can grow in water mentioned in the previous article. Growing in water means completely submerging the plant in water, while bottle-grown water culture means that part of the plant's root system grows in water, while the branches and leaves still grow in the air. The two should be distinguished.
