The potted lotus planting method allows seedlings to retain the essential traits of the original species. Key techniques include: (1) Selecting suitable potted varieties such as Jade Bowl, Red Tower, Mountain, Pink Pocket, Table Jane, Red Peony, and Small Silver Ball. These varieties bloom earlier, more frequently, and have a longer flowering period. (2) Choosing appropriate pots—such as clay, plastic, or bonsai pots—with a diameter and height ranging from 18 to 28 cm. Smaller pots are elegant, while larger ones support more foliage. Ensure the pot's bottom is sealed with cement to prevent water leakage. Prepare the soil by using farmland soil or unpolluted pond mud, soaking it in water for two weeks before use. (3) Planting should be done in mid-March in the south and mid-April in the north. In recent years, Liujia Garden in Anhui has used plastic film covering, advancing planting and blooming by 3-4 weeks. This simple technique significantly improves results. (4) Avoid adding base fertilizer during initial planting. Place the tuber at an angle downward, with only one plant per pot. Add 12–15 cm of soil or garden mud, keeping the water level 2–3 cm below the rim. After leaves emerge, apply a small amount of granular or compound fertilizer. (5) Position potted lotus in sunny, well-ventilated areas. With proper care, buds appear by late May, and full flowering begins in mid-June, lasting until mid-September. (6) Potted lotus is generally pest-free, but in areas with poor ventilation or near vegetable gardens, aphids may appear. A diluted solution of water and detergent (600–800 times) can be sprayed. Recently, Liujia Garden has used plastic film to cover potted flowers, using sunlight to steam and kill pests. This method controls temperature and humidity effectively, eliminating the need for insecticides and promoting healthy growth.
For seed propagation, choose large, shiny lotus seeds and plant them between April and June. First, manually crack the hard seed coat. Rub the pointed end on a rough surface or use a vise to create a small opening. Soak the seeds in warm water (20–30°C) in a thermos, changing the water twice daily. Within a week, sprouts will appear. Once sprouted, place them in a sunny, sheltered area with shallow water. After two weeks, fine roots and floating leaves will develop, making it ready for potting. Each pot should contain only one plant, and flowering can begin by mid-July.
To achieve off-season blooming in August and September, use late-flowering, cold-resistant lotus seeds. Sow the seeds and transplant the seedlings into a plastic greenhouse, maintaining a temperature between 20–30°C. During winter, install a reflective surface made of mirrors or aluminum foil on the north side of the pots to enhance light exposure. This helps the lotus bloom from New Year’s to the Spring Festival, extending the flowering season and offering a beautiful display during the holiday period. This method not only provides ornamental value but also increases the marketability of potted lotus plants.
Polyols are a group of alcohols that contain two or more hydroxyl groups in their molecules. The general formula is CnH2n+2-x(OH)x(x≥2). Polyols are generally soluble in water. Most polyols are viscous liquids or crystalline solids with high boiling points, strong solubility in polar substances, low toxicity and volatility. The boiling point, viscosity, relative density and melting point increase with the increase of molecular weight.
