When is the best time to plant Chinese牡丹 (Sedum aizoon)
Chinese牡丹 (Sedum aizoon) is more suitable for planting in the fall every year, specifically from mid-October to mid-November. This is mainly because the temperature is suitable at this time, allowing the plants to grow better after sowing. It is recommended to pre-germinate before sowing to ensure the seeds are fully hydrated. This way, seedlings can emerge in about a week, and the germination rate will significantly increase.
Chinese牡丹 (Sedum aizoon) flowering period
The leaves of Chinese牡丹 (Sedum aizoon) resemble celery, and the flowers resemble peonies, hence the name "Chinese牡丹." Chinese牡丹 cannot bloom throughout the year, and its flowering period is from April to May. A single flower can bloom for more than half a month, and if there's no rain, wind, or hot weather, it can even bloom for nearly 25 days.
When Chinese牡丹 blooms, there are usually 1-4 flowers, each with 5-10 petals. The flower colors are rich and vibrant, ranging from solid colors to white backgrounds with pink borders, gradient yellows, and more.
Planting time and method for Chinese牡丹 (Sedum aizoon)
The leaves of Chinese牡丹 (Sedum aizoon) look very similar to celery, and the flowering shape resembles peonies, thus called Chinese牡丹. Chinese牡丹 can be propagated through grafting, dividing, and sowing, with dividing and sowing being the most common methods. Different methods have different planting procedures.
Grafting
After the Chinese牡丹 flowering period, choose a suitable rootstock, with peony roots being the best. Cut a 10-18 cm branch, ensuring it has 1-2 buds. Both current-year soil buds or new branches can be used as scions. Insert the scion into the rootstock's cut, and after the grafting takes, it needs to be cultivated for 2-3 years before it can bloom and be transplanted.
Dividing propagation
Chinese牡丹 is suitable for dividing propagation in September-October every year. Dig up the Chinese牡丹 plant from the soil, gently shake off the old soil, then divide the plant, ensuring each division has roots. Trim long, rotting, or decayed roots with scissors and place them in a shaded area to dry for 2-3 days before replanting.
Chinese牡丹 prefers loose, fertile, and well-drained soil. After planting, place it in a well-ventilated area with diffused light, and water to keep the soil moist, avoiding waterlogging.
Seeding
The best time to sow Chinese牡丹 is from mid-October to mid-November. Soak the seeds in water for 24 hours, then wrap them in gauze and control the ambient temperature at 10-15℃ for germination. Rinse with clean water in the morning and evening, drain the excess water, and always keep the seeds moist.
Chinese牡丹 prefers well-drained neutral or slightly alkaline soil, and the sowing depth should not exceed 3 cm. Maintain a daytime temperature of around 20℃ and a nighttime temperature of around 10℃. Germination can occur in 20-30 days, and the plant will bloom in April of the following year.
