Brazilian jasmine flowers bloom continuously from early spring to late autumn, with pink, peach, bright red, etc., and rich in variety, and is known as the "queen of tropical vine". Brazilian jasmine likes warm and wet conditions, but it does not branch well.

Brazilian jasmine (Mandevilla sanderi) is a perennial evergreen vine of the oleander family.
Leaves of glandular vine (Mandevilla sanderi) are oblong, large, wrinkled, sub entire, dark green, glossy, apex acute, leathery; The color is bright, funnel-shaped, mostly dark pink; Beautiful and unique branches, branches soft, can do a variety of modeling. Double glandular vine from early spring to late autumn flowers constantly, flowers from the bottom to the top have been open, the color of flowers from spring to summer more and more deep, more gorgeous, give a person with the feeling of rich and rich flowers, ornamental value is very high, love.
The flowers of Brazilian jasmine (Mandevilla sanderi) are axillary, with funnel-shaped corolla. The colors of the flowers are red, peach, golden red, pink, etc., and rich in variety. It is called "queen of tropical vine".
Brazilian jasmine (Mandevilla sanderi) bloom flowers mainly in summer and autumn, and can blossom in other seasons if properly maintained.
Brazilian Jasmine (Mandevilla sanderi) is distributed in tropical America.
Brazilian jasmine (Mandevilla sanderi) likes warm, humid and sunny environments, and it can also be placed in a slightly shaded place, but lacks light and less flowering. The suitable temperature for growth of Brazilian jasmine is 20-30 ℃, and it has strong adaptability to soil, but the sandy loam with rich humus and good drainage is the best.
The optimal illumination intensity is 10,000-20,000 Lux. They are fond of warm and sunny environments, and are not cold resistant. They grow at a temperature of 20℃ ~ 30℃, and their growth is inhibited when the outdoor temperature is below 7.5 °C.Beijing area should be in winter, winter may fall leaves, until the spring blooms again.
Too dry soil affects fertilizer absorption, and too wet soil can cause root death or other diseases. Especially in winter, you need to reduce watering and keep the soil dry. Increase watering in summer to prevent the soil from drying out completely. Outdoor cultivation should not be planted in too low-lying places, so as not to water caused by hypoxia and poor growth. The most suitable air relative humidity is 70-80%, which should be under 50%.
Brazilian Jasmine (Mandevilla sanderi) has strong adaptability to soil. The basin soil needs to be well drained, and it is better to add a modifier and humus matrix.
Indoor potted north usable rot leaf soil adds a small amount of coarse sand, the south can use pond mud, peat soil, river sand to press 5:3:2 mixed preparation. In the growing period of Brazilian Jasmine, it can be an appropriate amount of topdressing compound fertilizer 3-5 times, but should control the amount of nitrogen fertilizer, so as to avoid excessive growth of nutrition and affect reproductive growth, so that the flowering reduces. In the maintenance process, to properly control watering, in order to form a developed root system.
Rational fertilization is needed in the vigorous growth period of spring and summer. Balanced slow-release fertilizer can be applied to the potted soil, followed by liquid fertilizer every 7-10 days.In general, in the spring, apply a balanced ratio of N, P and K compound fertilizer, such as 15-15-15, twice a week, about 150ppm each time; In late spring or early summer, 150ppm of phosphate fertilizer, such as 10-20-10, can be added to promote flowering. When serving the pot, add some slow - release fertilizer is also possible. Burning symptoms at the tips of leaves, or black spots on the top and sides of leaves, indicate a possible lack of fertilizer.
After the flowering period can be pruned, if it is a biennial plant, it can be lightly cut, pruning is mainly for plastic. Perennial plants can be strongly cut in spring to promote the germination of strong new branches.
Occasionally removing the growing spots helps maintain the shrubby shape of the plant, promotes branching, and makes the plant fuller.
Highly growing varieties tend to overgrow pots, causing a lack of fertilizer, yellowing of lower leaves and non-flowering. As soon as possible, remove the old support and wrap the straggling branches around the new support.
Brazilian jasmine (Mandevilla sanderi) can be propagated by sowing, cutting, and tissue culture.
When sowing, the temperature is required to be between 18-23°C, and it is generally carried out in spring. Cuttage is the most common method, often in late spring or early summer to choose half lignized branches, generally an internode used to do cuttings. Its cutting rooting time is longer, want 1 month above, dip in raw root powder can accelerate rooting.
The diseases of Brazilian Jasmine (Mandevilla sanderi) are mainly leaf diseases such as leaf spot and leaf blight caused by tailospora, and root rot and stem rot caused by fusarium. Carbendazim and mancozeb can be used to control the diseases in the early stage.
Prevention of root rot involves selecting a well-drained substrate, watering alternately between wet and dry, and placing the plant in a bright, hot place.
Red spider and whitefly are the insect pests with the greatest harm, which can be prevented and treated with imidacloprid.
Place: indoor potted plants should be placed in a bright place with a certain amount of scattered light. We must pay attention not to put the powder palm in the environment with strong direct sunlight. Brazilian jasmine is resistant to stress and rarely infects diseases, so it can be prevented by spraying a microbicide once a month during the growing season.
Brazilian Jasmine can be used as indoor balcony viewing, its tendrines naturally strong, and can be in the indoor sunny balcony potted ornamental. During the flowering period of the big flowers in red and pink competition to open, bursts of pungent fragrance makes people relaxed and happy.
Brazilian Jasmine can also be used for outdoor viewing. It likes strong light and has strong heat resistance, so it is suitable for cultivation in summer courtyards in the north and south. It can be used for beautifying small courtyards such as containers, fences, trellises and rooftops to make the courtyards full of tropical exotic atmosphere.
