(1) Flower basket type: On the premise of trimming the flowers into a large plane, leave a 500-600mm long branch at the diagonal corners of the flower plane, and gently bend the branches inward. , overlap at 100-200mm, and tied together to form the handle of a flower basket. This is a flower basket type.

(2) Multi-tower type: Cut out all the side branches, leaving only one or three upright branches. If three branches are left, they must be tied or braided together until they grow to the ideal height. , cut off the top to allow side buds to sprout, and remove excess buds at intervals of 400-500mm to form a multi-tower shape.

(3) Cliff type: The binding method is used to make some branches droop, like a cliff, which is called cliff type.

To encourage flowers

Full pattern: that is, the whole tree is in flowers. The method to promote flowering is to apply a 1:1:1 compound fertilizer 45 days in advance and then control the water. After the leaves wilt, add a small amount of water and combine it with leaf spray. Repeat this until all the leaves fall off, then water thoroughly. What is born at this time will be a tree full of flowers. This process must be carried out under full sunlight.

Bougainvillea is a plant that likes high temperatures and strong sunlight, so potted bougainvillea should always be placed in a sunny place. This is not only beneficial to its vegetative growth, but also beneficial to reproductive growth.

1. Often exposed to the sun

Bougainvillea is a plant that likes high temperatures and strong sunlight, so potted bougainvillea should always be placed in a sunny place. This is not only beneficial to its vegetative growth, but also beneficial to reproductive growth. Practice has proved that plants treated with strong sunlight have short internodes, substantial growth, large number of flowers, deep flower colors, and a long flowering period.

2． Prune frequently

Bougainvillea has a long growth period and a fast growth rate. The plant shape must be fixed and maintained through timely pruning and topping. Topping also helps encourage new shoots to bloom more - because flowers only bloom at the tops of new branches. Pruning is generally done in spring and summer. Pruning after mid-August will affect flowering and should not be done again. The pruning objects are inner branches, slender branches, leggy branches, cross branches, etc. Some branches that are too long should also be cut short with 1 to 2 bud eyes.

3． Strict watering

Purple bougainvillea should start watering 5 weeks before flowering (that is, around mid-August). After watering once, wait until the leaves and buds have drooped before watering again. The degree of water deduction shall be subject to the fact that the plants do not dry out to death. Repeat this process until the rudiments of flowers appear between the leaf axils at the ends of the branches, and then gradually return to normal watering. Withholding water increases the concentration of cell fluid, thereby promoting the differentiation and formation of flower buds.

4. Clever Fertilization

Bougainvillea is very sensitive to urea and still needs to be fertilized with urea once in the early growth stage of the flower branches to facilitate the growth of the flower branches. Among the above four measures, the last two are the most important. If these two are well mastered, the adverse effects caused by insufficient sunlight can be completely overcome.
