Distribution of Plumeria rubra

Plumeria rubra is cultivated in Guangdong, Guangxi, Yunnan, Fujian and other provinces of China, which is wild in the mountains of southern Yunnan. Plumeria rubra is native to Mexico; It is widely grown in tropical and subtropical Asia. 

Plumeria rubra growth environment

The Plumeria rubra is a hot, humid, sunny, well-drained environment, strong in nature, able to withstand drought, but fear cold, avoid waterlogging, like acidic soil, but also resistant to alkalinity. It is better to cultivate acid sandy loam with deep, fertile, transparent and rich organic matter. The optimum temperature is from 23℃ to 30℃. In summer, the plant can withstand extreme high temperatures of 40℃, and the temperature is below 15℃. The deciduous dormancy of the plant begins until about April of the next year. In the temperate zone cultivation of winter is easy deciduous. In the south of China, it can be planted, but also appropriate pot plants. The Yangtze River basin and the north can only pot plants, 80 cm to 150 cm high, when flowering sends out fragrance.

Plumeria rubra cultivation technique

Plumeria rubra prefers hot and humid climate, drought tolerance, and prefers lime rock ground, which is easy to survive cuttings propagation. Generally appropriate in the middle and late may, from the base of the branch pruning take branches long 20-30 cm, cutting the mouth has white milk outflow. It needs to be placed in a cool and ventilated place 2-3 days, so that the wound forms a layer of protective film and then cuts. Cutting with milk is easy to rot.Insert into a clean vermiculite or sand bed or shallow sand basin and spray water. Place it in an indoor or outdoor shade and spray water once every other day to keep the substrate moist. 15-20 days later, move it to a half after the plug in the shade, to see the weak light. It takes 30-35 days to take root, 45 days on the basin. T timely transplanting basin in diameter 20 cm, frangipani on soil is relaxed. Appropriate planting in the loose soil, containing humus more basin can be slightly visible when plant root. Plumeria rubra grows rapidly and needs to be changed once a year in spring. Generally, they can be changed into a pot with a diameter of 30 cm. The pot soil can be mixed and prepared according to 4 portions of garden soil, 4 portions of horse dung and 2 portions of river sand. After changing pot planting, pour permeable water, grain rain before and after the relocation of the outdoor sunny place. 

Plumeria rubra prefers warm, wet and sunny environments, no shading is needed in summer. It can be placed outside for sun exposure. Summer and autumn two seasons are frangipani growth, flowering period, watering every night 1-2 times. In the summer and autumn, it should be promptly poured out of the basin water. From June to November, apply liquid fertilizer once every 10 days or so, with a concentration of 15%. Southern frilled frilled flowers are planted in open fields. They lose their leaves in winter and regenerate them in spring the following year. Potted plants in the north should be moved to the south window in mid-late October, pay attention to ventilation and light. The room temperature should be above 10℃, low temperature and poor indoor ventilation will make the plant leaves, indoor watering once every two weeks.

Plumeria rubra main value

Plumeria rubra flower is white yellow heart, fragrant, large dark green leaves, beautiful crown, often planted for ornamental. Guangdong, Guangxi folk often pick its flowers dry tea drink, which has the treatment of damp heat dysentery and detoxification, runfei. Propagation methods can be cut or layering, and are very easy to survive.
