Choose the place

Cultivation place, should choose the sunny, ventilated cool place. Orange Trumpet Vine is less soil intensive, but grows better when planted in rich, well-drained, rich, rich soil.

Planting hole to dig a little bigger, and apply sufficient base fertilizer, base fertilizer should be used to decompile and add an appropriate amount of bean cake or bone meal.Hole soil to mix evenly, and need to pour 1 time to permeate, let it ferment for 1 ~ 2 months before colonization. After the first watering thoroughly, it needs shade. When waiting for seedlings to grow tall 70 cm or so, we need to set scaffold, pull its branch on the frame, and we need to undertake picking the heart, making a germination side branch, in order to be conducive to more flowering. 

Water

Fertilizer and water should be appropriate. Fast production, lots of flowers, long flowering period, so full of fat and water should be needed. Top dressing should be applied once a month during growth. Top dressing should be used with decrepit and thin bean cake water or compound chemical fertilizer to promote its luxuriant foliage and blooming branches. To keep the soil wet, the number of watering should depend on the soil wet conditions, in hot summer in addition to watering, but also to the branches and leaves every day 2 ~ 3 times and around the ground sprinkling water, in order to improve the air humidity. Autumn into the flower bud differentiation period, watering should be reduced, fertilization should be turned to phosphate fertilizer. During the growing season, thin liquid fertilizer combined with nitrogen and phosphorus should be applied once every 2 weeks or so. Pregnant bud period topdressing with nitrogen fertilizer - based liquid fertilizer, for the benefit of flowering and plant growth. Watering should be sufficient, at the same time to sprinkle water on the ground near the pot, in order to improve the air humidity. In autumn, it began to enter the flower bud differentiation period, and watering needs to be appropriate less at this time, in order to control nutrition growth, to promote flower bud differentiation.

Maintenance

Orange Trumpet Vine (Pyrostegia venusta), a perennial, evergreen climbing vine having a tendrils that allow it to grow upwards with the aid of other plants. For family cultivation, in order to improve the ornamental effect, large and deep pots can be used when planting. When the seedlings grow to a certain height, a flower stand can be built in the pot, and the stems and tendrils are tied to the flower stand, and the distribution should be paid attention to evenly, and the plants should be placed on the balcony with sufficient sunlight for maintenance. Also we can plant it inside a big basin, a flower frame is set on the balcony, let it climb upward to grow, when waiting for the branch to grow to a certain height on the attached object. We need to hit top, make buds new branches, and facilitate blossom more. Open the branch that spends, the coming year is not in blossom, and the new growth branch wants a pregnant bud, because this is right a few old branches, weak branch to wait to want timely cut off, lest consume nutrient, affect the second year blossom.
