When does bougainvillea bloom? When does bougainvillea bloom? What are the symptoms before flowering?
Bougainvillea usually blooms around 1 1, and the flowering period is about two months. It is very common in the south, and potted plants are used in the north. Indoor temperature, light and fertility can meet the needs of plants, and continuous flowering and multiple flowering can be controlled in one year.
Symptoms of bougainvillea before flowering: the new leaves at the top of the branches grow very little, the branches grow slowly and become stout, and the new leaves are smaller and redder than the old ones.
Bougainvillea likes light, potted plants can be placed in a bright and ventilated place on the balcony, and the dark light is easy to grow white and cannot bloom.
Bougainvillea is drought-tolerant. Generally, it can be thoroughly dried and watered. If the soil is not dry, don't water it for fear of waterlogging. Roots rot easily when humidity is high.
Controlling watering before flowering and topdressing phosphorus and potassium fertilizer can promote plant flowering.
Bougainvillea grows faster, so we need to pay attention to pruning, cut off long branches, promote the growth of lateral branches, have full shapes, and look better with more flowers at the top of branches.
When do Chinese parasol trees and bougainvillea bloom?
Sycamore trees bloom in June and July. Bougainvillea can blossom only when it is above 15℃.
Platanus acerifolia is a tropical tree species, which began to blossom after 6-8 years of planting. Platanus acerifolia flower border surrounded by high temperature and high humidity sunshine, the growth temperature is 20-30℃, it is not cold-resistant, and the winter temperature is not lower than 10℃. It is suitable to use deep and fertile sandy loam rich in organic matter; Fear of stagnant water, good drainage and drought resistance; Fertile soil Generally, the height of 1 year-old can reach1.5 ~ 2m, and the height of 2-year-old can reach 3 ~ 4m. Flowers begin to bloom after 6~8 years of planting.
Bougainvillea likes warm and humid climate, not cold-resistant, high-temperature resistant and afraid of drying. It is safe to overwinter above 3℃ and bloom above 15℃.
I like plenty of light. The requirements for soil are not strict. It grows well in well-drained clay loam and well-drained sandy loam, and is resistant to barren, alkali, drought, waterlogging and pruning.
When did bougainvillea bloom?
The flowering period of pruned bougainvillea is generally between 1 1 ~ 12. If properly managed, it will bloom all year round.
Therefore, after flowering, it is necessary to prune properly, cut off pedicels, retract13 branches, and sparse weak branches, short branches and internal branches. Pruning should be short, heavy and sparse in combination with soil replacement in winter.
Short, short-cut, branches with 1/3 reserved; Heavy, used to cut long branches; Thinning refers to thinning weak branches to make them grow strong branches again, which is also called renewal pruning. The cut branches can be reserved for cutting seedlings. Bougainvillea bougainvillea is planted in the south as a flower stand, fence and doorway. In winter, bougainvillea doesn't rest or shed leaves, but it is only lightly cut, but it should be tied, distributed and pulled so that the flower branches can stand evenly, be distributed reasonably and be covered with flowers.

How long is the flowering period of bougainvillea?
Rattan shrub. Stems stout, branches drooping, glabrous or sparsely pilose; Axillary spine,
Phyllanthus
5- 15mm long. Leaf blade is papery, ovate or ovate-lanceolate, 5-65438 03cm long and 3-6cm wide, with a sharp or tapering tip, a round or wide wedge-shaped base, hairless upper part and puberulent lower part; Petiole length 1 cm.
Among the three bracts of the top branch of the flower, the pedicel is attached to the bract midvein, and a flower is born on each bract; Bracts leaflike, purple or magenta, oblong or oval, 2.5-3.5 cm long and 2 cm wide, papery; The tube is about 2 cm long, light green, sparsely pilose, angular and 5-lobed at the top; Stamens 6-8; Style lateral, linear, margin spread into thin slices, stigma pointed; The base of the disc is unified into a ring, and the upper part is torn. The flowering period is between winter and spring (Guangzhou, Hainan and Kunming), and it blooms in greenhouse cultivation in the north from March to July.
When does bougainvillea bougainvillea bloom?
The flowering period can start from June 1 1 to June of the following year.
The florescence of safflower and purple flower is the same. The key is the correct cultivation method.
Habits: like warm and humid climate, not cold-resistant, belonging to short-day plants, unable to differentiate flower buds under long-day conditions, like light and not tolerant of shade. The southern region can overwinter in the open air,
In the north, it is cultivated as a greenhouse flowerpot. The requirements for soil are not strict, but soft and fertile soil is suitable for potted plants. They like a lot of water and fertilizer, are extremely drought-tolerant, and are prone to falling leaves due to insufficient water supply during the growing period.
Cultivation and maintenance: the cultivation soil of Phyllanthus urinaria can be directly made of whole leaf soil or humus soil mixed with cow dung and sand. Because of the rapid growth, it has to be replaced every year. Open-air cultivation can be shrub-like or grid-like. Potted plants are mainly shrub-like, which can be maintained by pinching or cutting short after flowering. The new branches of leafy peanuts grow very fast for a long time, which easily makes them ugly trees and messy branches. Therefore, it should be cleaned and reshaped in time, and the dense inner branches, dead branches, old branches and diseased branches should be cut off or trimmed in time to promote the growth of more robust branches to ensure the prosperity of flowering. Regardless of indoor and outdoor maintenance, it should be placed in a sunny place, watered in summer, and the amount of watering should be reduced appropriately after flowering. Top dressing once a week during the growing season. 10 is moved to a high-temperature greenhouse for wintering in early October, which can keep flowering, and the room temperature is not lower than 10-12c to reduce defoliation. If you want the National Day to blossom, you can have a short sunshine treatment 60 days in advance, with 8 hours of sunshine every day.
How to control the flowering time of bougainvillea?
Let bougainvillea bloom more and longer.
1. Suitable for the site and suitable for the tree-the correct selection of varieties means choosing varieties suitable for local planting under suitable geographical and climatic conditions. Bougainvillea bougainvillea: It requires low temperature (it can be safely wintered above 3℃), and can be cultivated outdoors in the north subtropical region, and is mostly used as hedges and scaffolding. Bougainvillea: It needs high temperature (above 10℃) to overwinter safely. In the south subtropical zone, it is widely planted outdoors. Suitable for potted plants in different places and cultivated into bonsai. In winter, it is placed in a greenhouse with sufficient light at 10~ 12℃. Adjusting the room temperature to 15~25℃ created conditions for flowering. Hybrid: The growth and overwintering temperature is higher than that of Bougainvillea glabra. Under special circumstances, the favorable small terrain (such as lee facing the sun, facing the sun and leaning against tall buildings) can meet the light and heat requirements of bougainvillea flowering with the help of sunlight reflection or thermal radiation from buildings under the sun. In the northern tropical areas (such as Kunming, Chuxiong and Dali), some precious bougainvillea varieties and hybrid bougainvillea can still bloom luxuriantly.
2. The daily watering of bougainvillea is based on the principle of "wet and dry". On the basis of plant management, proper pruning and fertilization, water should be controlled 50 days before flowering. At first, the leaves and branches wilted and wrinkled slightly without watering for 3~5 consecutive days, then the canopy was sprayed with water every afternoon, and the watering was resumed on the fifth day of/kloc-0. It can promote the formation of flower buds, and can be properly fertilized after the flower buds grow.
3. Apply more phosphorus and potassium fertilizer to control fertilizer, topdressing phosphorus and potassium compound fertilizer or poultry manure once a month in slow growth period, topdressing cooked cake fertilizer and water once every half a month in vigorous growth period, and adding appropriate amount of ferrous sulfate (to prevent iron deficiency and yellowing of leaves), which can promote flower bud differentiation and be beneficial to flowering.
4. Change pots in time after pruning, and prune appropriately according to the purpose of plant cultivation and growth. The outer branches and leaves in the middle and upper part of bougainvillea plant bloom the most, while the long branches, inner branches and overlapping branches consume more nutrients and bloom less. Therefore, after flowering, the pedicel should be cut off, and the flower branches should be retracted by 1/3, leaving only 2~3 nodes in the bud to remove the redundant parts and promote the germination of the flowering mother branches. Re-cut long branches, lightly cut side branches, and delete all inner branches (branches that grow into branches) and overlapping branches (overlapping branches that grow up and down) to form a plant shape with good ventilation and light transmission. In addition, more flowering lateral branches can be cultivated by gently cutting off the extended branches (about one-fifth of the length). When the new shoots grow to 6 leaves, remove the core and keep 4 leaves. Repeated coring several times in the growing season can cultivate enough complete flower branches.
5. Chemical control and spraying CCC and paclobutrazol can inhibit vegetative growth and promote flower bud differentiation.
