What are the methods and precautions for growing Bougainvillea?
Although bougainvillea is a toxic and thorny plant, this does not stop people from liking it. More and more people bring bougainvillea home to grow, though not everyone can grow it well. But those who can grow bougainvillea well must be people who have mastered bougainvillea growing techniques and methods.
How to grow bougainvillea
1. Control water to encourage blooming: Bougainvillea especially loves strong light and high temperatures, is not afraid of full sun exposure, and does not require much water; it is enough to keep the potting soil moist. In autumn and winter, be sure to control water for 1 month, keeping it half dry and half moist; even if green leaves fall, it does not matter. Water control actually helps promote blooming, which is why home-grown bougainvillea "blooms little when tended diligently, but blooms constantly when neglected."
2. Root pruning and rejuvenation require water control: Bougainvillea is vigorous, sprouts strongly, and is especially tolerant of pruning. Regular pruning and shaping can make its branches numerous and flowers abundant. It should be noted that it has the unique habit of first sending out buds, growing branches, and rooting. When repotting and pruning the roots of old potted plants, do not water immediately; water thoroughly once two days later. After that, keep it moderately moist. Once the new shoots and stems have basically grown out, gradually switch to normal watering and place it in a spot with ample sunlight at a temperature of about 25°C.
3. Keep warm and control water for overwintering: Bougainvillea likes warmth, is not cold-tolerant, and dislikes waterlogging, so attention must be paid to keeping it warm and controlling water in winter. In winter, maintain a temperature above 7°C, otherwise it will freeze and die. Once the temperature drops sharply, the plant will shed a large number of leaves, and at this time it must absolutely not be overwatered. It should be placed in an environment of 10°C to 15°C, watered about once every 10 days, and when it sprouts and grows leaves the following spring, gradually increase the amount of watering. Otherwise, it will lead to root rot and death.
Bougainvillea growing methods and precautions
1. Soil selection
Bougainvillea soil is generally made by mixing garden soil, leaf mold, and fine sand, with an appropriate amount of bone meal added. If you buy a small pot of bougainvillea directly from a flower market, there is no need to change the soil in the short term; using the original soil is enough. After growing it for 1-2 years, when repotting, replace part of it with new soil. The mixing ratios are as follows (I would not tell just anyone):
Mix garden soil: leaf mold: sand at a ratio of 5:3:2, or mix peat soil: leaf mold: sand: perlite at a ratio of 5:2:2:1.
2. Watering method
Bougainvillea has a relatively large water requirement, and watering differs slightly by season:
In spring, as bougainvillea growth gradually speeds up, it needs watering every day, and the leaves and surroundings should often be sprinkled with water to increase air humidity. If less water is given in spring, leaf drop may occur due to insufficient humidity.
In summer, bougainvillea needs water; water twice a day, spray water in the morning, and water once after 4 p.m.
In autumn, after the temperature drops, just keep the potting soil moist. When the temperature is below 10°C, reduce watering and keep the potting soil on the dry side. If the temperature is above 15°C, watering can be done appropriately.
In winter, reduce watering; do not water unless the potting soil is dry.
3. Fertilization method
Bougainvillea likes fertilizer. After the weather turns warm in spring, apply nitrogen fertilizer once every 10-15 days; during the growing period, apply cake fertilizer water once a week; during the flowering period, increase phosphorus fertilizer several times. After autumn turns cool, reduce the amount of fertilizer, and stop fertilizing in winter. During the peak growing and flowering seasons, foliar spray can be applied 2-3 times with 1000 times diluted monopotassium phosphate solution, or a general-purpose fertilizer can be applied once every 10 days.
4. Light and temperature requirements
The suitable temperature for bougainvillea growth is 20-30°C. In winter, below 5°C, leaf drop will occur.
Bougainvillea likes light. With insufficient light, the plant grows weakly, which affects flowering. In winter, place bougainvillea in a bright place, and the daily light duration must not be less than 8 hours, otherwise large-scale leaf drop will occur.
5. Pest and disease control
Bougainvillea has relatively few pests and diseases, generally appearing in winter and spring. When moving outdoors and indoors, it may suffer damage from scale insects and slug moth larvae. In home care, remove them promptly when found and spray pesticide.
Bougainvillea variety characteristics
1. Bougainvillea is easy to propagate and grows quickly
When propagating bougainvillea, cuttings are mostly used; the survival rate is relatively good, and propagation is relatively simple. Generally, bougainvillea is propagated from March to June. With sufficient water, fertilizer, and light, it can grow quickly.
2. Bougainvillea has many varieties and rich flower colors
Although we say flower colors, this mainly refers to the colorful bracts of bougainvillea. The colorful bracts of bougainvillea actually come in many colors. Besides the most common purple, there are also patterned, yellow, white, and others. The bracts may be single or double, and all are very beautiful.
In addition, bougainvillea also has some artificially bred varieties; through grafting, it can even have multiple colors on one tree, and its ornamental value is truly very high.
3. Bougainvillea has a long flowering period and high ornamental value
Bougainvillea's flowering period is very long. Although the small flowers of bougainvillea are not that showy, they are also quite lovely, and together with the long-lasting colorful bracts, many people will surely enjoy admiring them.
Generally, bougainvillea can be used as urban landscaping plant, while for home growing it is usually potted for ornamental display; both have unique ornamental value.
Can bougainvillea be grown at home
Although bougainvillea is a toxic plant, it can be grown at home.
On the one hand, although bougainvillea is toxic, it also has good medicinal value. Its leaves can be used medicinally; mashed and applied to the affected area, they have the effects of dispersing blood stasis and reducing swelling, promoting blood circulation and regulating menstruation, and resolving dampness and stopping vaginal discharge. They have notable effects in treating blood stasis amenorrhea, irregular menstruation, and red and white vaginal discharge. This shows that bougainvillea is not only toxic; it can also serve as a good medicine to treat illness.
On the other hand, the toxicity of bougainvillea is mainly in its sap; if it is not eaten by mistake, it will not cause poisoning. Moreover, bougainvillea has high ornamental value, and as a home plant, it is also good for decorating the home.
Therefore, growing bougainvillea at home is worth a try.
Although bougainvillea contains a certain toxicity, it can still be grown at home, because the toxicity of bougainvillea is very weak. As long as bougainvillea is not eaten, it will not cause any harm to the human body. At the same time, bougainvillea has strong ornamental value and medicinal value, so growing bougainvillea still has more advantages than disadvantages.
