The site for site preparation and selection should be warm, humid, sunny, well-drained, loose, rich in organic matter, and preferably slightly acidic loam or sandy loam. For potted plants, neutral or slightly acidic soils are suitable, while peat-based mixes enriched with phosphate fertilizers are commonly used as growing media.
Breeding methods primarily involve cuttings and high air layering.
(1) **Cutting Propagation**: Before spring, select mature, non-budding shoots from the previous year, cut them into 10 cm sections, and insert them into a propagation bed with leaves intact. Water thoroughly, cover with plastic film, keep the environment moist, and place in a semi-shaded area. Maintain high temperature and humidity, ideally around 28°C and 95% relative humidity. Summer is the best season for cuttings due to the naturally high heat and moisture levels. With proper care over 50 days, roots should develop. Soaking cuttings in naphthalene acetic acid, butyric acid solution, or vitamin B12 can enhance root development and increase survival rates. After one month, seedlings can be transplanted into pots and grown for 2–3 years before final planting.
(2) **High Air Layering**: This method is ideal for potted plants. In spring or summer, choose 1–2-year-old shoots with a diameter of 2–5 cm, and make a ring cut about 6–9 cm from the branch point. The incision should be slightly dried before wrapping it with moist soil, moss, vermiculite, or a mix of loam and cow dung. Cover the area with plastic film and water regularly to keep the wrapped section moist. After about two months, rooting begins, and after 3–4 months, the new plant can be separated from the mother plant and potted or transplanted.
(3) **Transplanting and Potting**: In warmer regions, transplanting is typically done during spring or summer. The potting soil should be fertile, consisting of 25% decomposed leaf mold, 50% compost, and 25% river sand, ensuring good drainage. A small amount of fully fermented cake fertilizer or slightly alkaline soil can be added. Peat soil mixed with phosphate fertilizer is also suitable. When planting in pots, ensure the spacing allows for adequate growth, and water carefully after transplanting. Avoid watering for about half a month to encourage new root development, and protect the plant from direct sunlight during this period.
**Field Management**: After transplanting, apply liquid fertilizer every 10–15 days using manure tea with ferrous sulfate. Spray leaves with room-temperature water before sunset to maintain humidity. During spring, when growth is vigorous, ensure sufficient water and high air humidity. In autumn, gradually reduce watering to maintain moderate moisture. Keep foliage clean by rinsing off dust with room-temperature water. In winter, maintain a temperature between 10–12°C. If temperatures rise above 18°C, the plant will grow and bloom normally, requiring watering every 2–3 days and occasional liquid fertilizer. Avoid overwatering below 12°C. Only water when the soil feels dry to the touch. When moving plants outdoors in spring, avoid direct sunlight and allow for a gradual acclimation period.
**Diseases and Pest Control**: Milan plants are generally resistant to diseases but are susceptible to aphids and leaf roller moths. Common pests include spider mites and scale insects, so regular ventilation is important. If infestations occur, spray with 1000–2000 times dilution of dimethoate or 100–150 times oil emulsion. For sooty mold, use 500–1000 times diluted carbendazim.
By following these practices, you can ensure healthy growth and vibrant flowering of your plants.
