The best breeding time: Generally, the cutting season should be carried out from March to June, Hangzhou is the best from late May to early June.

The best growing soil: Bougainvillea has less stringent soil requirements, is resistant to infertility and drought, and avoids standing water. Sandy soil that is rich in humus, loose, fertile, and highly permeable is better, and clay is not used.

Humidity requirements for growth: When growing Bougainvillea, the potting soil needs to be kept moist.

Optimum growth temperature: The suitable temperature for the growth of Bougainvillea is 15 ~ 30 ℃. In the summer, it should be properly shaded or sprayed with water and ventilated. In winter , the ambient temperature should not be lower than 5 ℃.

The best growth light: In addition to the new plantlets in the four seasons should be placed in the shade. In winter, it should be placed in front of the south-facing window, and the light time should not be less than 8 hours.

Notes on growing Bougainvillea:

Fertilizer application: Bougainvillea needs certain nutrients, and it must be properly fertilized during the growing period to meet its growth needs. Fertilizer should be decomposed, fertilized in a small amount and many times, the concentration should be light, otherwise, it will easily damage the root system and affect growth.

Planting and potting: Bougainvillea cuttage survives branching into pots, cuttings that survive for 40 days are planted under strong sunlight for a week, and thinly fertilized. 50 to 60 days, plant the pot, cut seedlings and put them into the water basin, bleach the substrate away from the root, or pour out the root directly to separate the substrate and plant it in the culture soil.

Watering points: Watering is also very important in the cultivation methods and precautions of Bougainvillea. Bougainvillea should be controlled before flowering. The leaves are usually watered. in principle. However, in order to make the leaves bloom neatly and multi-flowered, water control must be performed before blooming.

The watering of the leaves has been controlled since September. Each watering can only be performed after the potting soil is dry and the branches and leaves are drooping. This is repeated for half a month, and normal watering is resumed after half a month. Do not fertilize during water control to prevent fertilizer from burning the roots. In this way, in about a month, the leaf flower can show buds and bloom, and the flower is open and neat and prosperous.

Reproduction points:

(1) Cutting propagation: The leaf flower reproduction is mainly cuttings, and the cutting survival rate is high in summer. Cuttings should choose annual semi-lignized branches, cut into 10 to 15 cm segments, and cut into sand beds at a temperature of 20 to 25 ° C. Next, rooting can take place in 20 to 25 days, and the pots can be planted after 40 days, and flowering can be achieved in winter the following year. Such as hormone treatment before cutting can promote rooting and improve survival rate.

(2) High-pressure breeding: ordinary weeding can be used for beading, which is usually carried out in spring and autumn. The beading portion can be nicked first, then buried in the soil, and maintained at a temperature above 20 ° C, and roots can be made in about 20 days.

Pruning essentials: Bougainvillea should master the principle of "short, heavy, and sparse" when pruning, that is, to cut horizontal branches and re-cut new branches. Thinning off weak branches. Red flower bougainvillea is relatively weak, and it is pruned about once a year in March-April; purple flower bougainvillea needs to be pruned twice a year, the first time before germination in March-April, and the second time in November-December. After the new branches grow, to ensure that the flowers bloom vigorously every year.

Pot soil replacement: Bougainvillea grows fast, the root system is developed, and there are many fibrous roots. Pots need to be changed once a year. Due to long-term watering, fertilization, and rain erosion, the bougainvillea is easy to settle. Therefore, it is necessary to loosen the soil regularly and remove the weeds in the pit soil to facilitate the growth of bougainvillea. Otherwise, the pot soil will stagnate and stagnant water, which may easily cause the root system of bougainvillea to rot or grow poorly.

Watering requirements: watering should be done once a day in spring and autumn, watering can be done in the morning and evening in summer, and watering should be controlled once a day in the morning and evening after the emergence of watering flower buds, while spraying water on the foliage 1 or 2 times. During the rainy season, water should be prevented to prevent plant death from rotten roots.

Disease and pest control: Common pests of Bougainvillea are leaf beetles and aphids, and common diseases are mainly blight shoots. Normally, weeding should be strengthened to remove weeds, remove dead branches and diseased leaves in time, and pay attention to ventilation to reduce the spread of disease sources. Strengthen the inspection of the condition and find that the condition is dealt with in a timely manner, which can be prevented with solutions such as Dimethoate and Tobbutin.

Experiences in growing Bougainvillea:

可以安全越冬,否则就要防冻保暖或移入室内养护。 1. Bougainvillea can be safely overwintered at a temperature of not less than 5 ° C in winter, otherwise it must be protected from frost and warm or moved to indoor maintenance.

2. Bougainvillea grows water under strong light and high temperature. Triangular Meite likes strong light and high temperature, it is not afraid of exposure, but it does not require much water, as long as the pot soil is kept moist. Especially in the beginning of autumn, you need to make water for one month and keep it half dry and half wet. It is okay to cause the green leaves to fall, but it is conducive to long flowers.

Conclusion: Through the introduction above, I believe that everyone knows the cultivation methods and precautions of Bougainvillea, I hope everyone can cultivate beautiful Bougainvillea!
