How to grow bougainvillea properly? A detailed guide to care methods and techniques

1. Potting soil

The potting soil for cultivating bougainvillea should be loose, with good drainage and water retention. Usually, the potting soil is prepared using leaf mold rich in humus.

2. Planting

Newly planted plants should first be placed in a semi-shaded environment for 1 week, and after their root systems regain their absorption capacity, they can be moved to a sunny place.

3. Light

Bougainvillea needs sufficient light for growth, so during the growing season it must be placed in a sunny place.

4. Temperature

The most suitable growing temperature for bougainvillea is 10-15°C, and the lowest temperature should not drop below 3°C, otherwise its branches will be damaged. Therefore, our bougainvillea is best kept in a ventilated, sunny spot.

5. Watering

Bougainvillea likes water but hates waterlogging, so when watering we should be careful: if the soil is not dry, we do not water.

6. Fertilizing

The amount of fertilizer also varies with the season. Fertilize more in spring and summer, and reduce the amount of fertilizer in autumn and winter.

7. Shaping and pruning

Bougainvillea has strong growth vigor, so it needs shaping and pruning every year, cutting off overly dense branches, dry branches, diseased and weak branches, etc., to encourage new branches.

By following these methods, you can not only grow bougainvillea but also grow very beautiful bougainvillea. If everyone can be even more careful about the watering and fertilizing requirements, you will definitely be able to grow beautiful bougainvillea. Do you want to know what value the bougainvillea you grow has?

Bougainvillea (also called triangle flower, ninefold kudzu) is also known as triangle flower, indoor flower, ninefold kudzu, spring greeting red, etc.
Nyctaginaceae
[Ornamental value of bougainvillea]
An evergreen climbing shrub in warm regions, shrub-like when potted, with alternate ovate leaves, flowers borne at the ends of club-shaped branches, blooming profusely from April to May, but if the temperature is 28°C, it can bloom all year round, with every three small flowers enclosed in two large purple bracts. Varieties include red bracts, brick-red bracts, orange-yellow bracts, and purple bracts, all extremely bright and beautiful, suitable for balcony potting, and for use on trellises, hedges and walls, and as cut flowers.

[Habits of bougainvillea]
It likes warmth, sufficient sunlight and loose, fertile soil, and during the winter dormant period it will not freeze to death if kept above 5°C.
[Key cultivation points for bougainvillea]
(1) In spring and summer, select plump branches, cut them into 10-12 cm lengths, insert half into sandy soil; at 28°C, they will root in 20 days, and after 1 month they can be potted, and they can bloom the following year.
(2) The potting soil uses six parts fine sandy soil mixed with four parts base fertilizer; the pot diameter is 25-30 cm, depth 20 cm, and the potting soil should not be filled to the brim, but kept 3-5 cm below the pot rim.
(3) Water as soon as the potting soil looks dry. If the plant's leaf color becomes pale and the leaves become thin, a dilute fertilizer solution should be applied immediately.
(4) In summer and autumn, pinch off the growing tips and prune overly dense branches and the top portions of branches. This is because strong new branches will grow after pruning.

How to grow bougainvillea - Propagation methods of bougainvillea

Bougainvillea, also known as triangle flower, belongs to the vine shrubs, will climb as it grows, and is a greening plant very suitable for home cultivation. How to grow bougainvillea? Let's look below at the answer and the propagation methods of bougainvillea.

How to grow bougainvillea

1. Soil

Cultivating bougainvillea requires loose, fertile, well-drained, slightly acidic soil. Generally, it can be prepared by mixing 1/4 each of leaf mold, peat soil, garden soil, and sandy soil, plus a small amount of decomposed cake fertilizer residue or bone meal.

2. Light

Bougainvillea likes light and prefers strong light. If there is insufficient light or it is kept in a shaded environment for a long time, new branches will grow thin and weak, leaves will become dull or fall off, and it will not bloom or bloom little. Therefore, except that newly potted seedlings can first be placed in a semi-shaded place to prevent them from dying, once the seedlings have grown they should be cared for in a sunny place.

3. Watering

Because bougainvillea grows vigorously, not only must nutrition keep up, but the water supply must also be sufficient. Especially in summer, it needs watering once each morning and evening, while in spring and autumn it changes to watering once every evening. But in winter, because the temperature is low and the plant is in a semi-dormant state, watering should follow the principle of not watering until dry, otherwise root rot easily occurs.

4. Fertilizing

Bougainvillea plants grow quickly and like fertilizer, requiring a full supply of nutrients. Therefore, in addition to adding new nutrient soil when repotting every 1-2 years along with changing the soil, during the growing period liquid fertilizer should also be applied frequently, generally once every half month with decomposed cake fertilizer water, and the concentration must not be too high; apply thin fertilizer frequently, and before flowering increase the application of quick-acting phosphorus fertilizer 2-3 times, or carry out foliar feeding, to ensure the nutritional needs during flowering. After each fertilization, water thoroughly promptly and loosen the soil, otherwise root rot or yellowing leaves may easily occur. Fertilizing should stop in winter.

5. Pruning

Bougainvillea is a vine plant, and its vines can grow more than 10 m, making it suitable for vertical greening. In southern cultivation, it is often made to grow drooping, that is, pinching off the growing tips at the seedling stage to encourage branching, keeping 3-5 sprouted branches per plant and letting them grow drooping; before long the hanging branches will be covered with flowers.

For potted plants in the north, pruning must be strengthened so they do not grow into a vine form. After flowering, cut off overly dense branches, slender branches, and leggy branches from the base of the plant, keep the retained branches about 30 cm long and then cut off the top shoots, and shorten all side branches to encourage new branches to sprout. It can also be pruned into a spherical crown to increase ornamental value. For old branches that have grown for 5-6 years, they should be renewed and rejuvenated to make the plant shape beautiful and robust.

Propagation methods of bougainvillea

Bougainvillea is usually propagated by cuttings, which can be done from May to August. When taking cuttings, choose woody branches after flowering as cuttings, cut them into 15 cm segments, and insert them into the cutting bed. Keep the cutting bed moist; the suitable temperature for the cuttings is about 25°C, and they can root in about 1 month. To promote rooting of the cuttings, they can be treated with 2×10 indolebutyric acid.

One month after rooting, transplant them into pots, with 1-3 plants per pot being suitable. Be careful to shade them; after the seedlings recover, give them sufficient light and proceed with normal management, and generally they can bloom the following year.
