The great bougainvillea will be moved to a cool and ventilated place for proper shade protection, and the Great Bougainvillea will be trimmed in time to increase air circulation. The following are steps to grow Great Bougainvillea.

1. Soil preparation

Great Bougainvillea likes loose, fertile soil to ensure that the soil is breathable and can be added with sand and gravel. Organic fertilizer was added to the soil to provide a proper nutrient supplement to the Great Bougainvillea. The Great Bougainvillea is often turned over to effectively promote the absorption of the root of the Great Bougainvillea, and there is more rain in the rainy season, so the soil drainage should be done well.

2. Plant treatment

The Great Bougainvillea plant is dug up and the damaged roots are properly trimmed to ensure the integrity of the roots. Proper pruning of the leaves of the Great Bougainvillea plant can reduce the consumption of nutrients. Place the roots in carbendazim solution, disinfect them, and then place them in a cool, ventilated place to allow the wound to dry.

Pour water to keep the soil moist, and place the Great Bougainvillea in a cool, airy place for proper shade protection. Control the temperature between 20 ~ 30℃, and wait for the germination of new branches and leaves.

4. Later maintenance

Rational fertilization

In order to make the Great Bougainvillea bloom more, it is necessary to ensure sufficient nutrients, and at the same time, the appropriate amount of fertilizer should be used properly.- April to July growth period, every 7 days to 10 days of liquid fertilizer - times, in order to promote the growth of plants robust, fertilizer can be 10 % to 20 % cooked bean cake, rapeseed cake water, or human dung water. Starting from August, in order to promote the gestation of flower buds, phosphate fertilizer was applied to fertilize them every ten days, and liquid fertilizer such as 20 % decomposed chicken, duck, pigeon dung and fish miscellany could be used. From August to the beginning of the flowering period, from now to the middle of October, apply a number of phosphate fertilizers every half a month, fertilizer water concentration of 30 % to 40 %. The Great Bougainvillea will continue to be replenished during flowering by applying top dressing after each flowering.

Control the water before flowering

Great Bougainvillea's usual watering master "don't water, watering is to thoroughly" principle. But for the Great Bougainvillea to bloom neatly and profuse, water control must be carried out before it blooms. Since September, the watering of Great Bougainvillea has been controlled. Every watering should wait until the basin soil is dry and the branches and leaves are soft and pendent. This is repeated for half a month, and the usual watering can be resumed after half a month. Do not apply fertilizer during water control, so as not to burn the root system. In this way, in about a month, the buds of the Great Bougainvillea will blossom, and the flowers will open neatly and abundantly. 

Loose soil weeding and change the basin

Due to long-term watering, fertilization and rainwater washing, the basin soil of Great Bougainvillea is easy to be hardened. Therefore, it is necessary to loosen the soil regularly and remove weeds in the basin soil to facilitate the growth of Great Bougainvillea. Otherwise, the basin soil is compaction and water accumulation, which will easily cause the root rot or poor growth of Great Bougainvillea. In addition, Great Bougainvillea grows fast, has developed roots and many fibrous roots, so it needs to be repotted several times a year.

Pruning should be proper

Great Bougainvillea grows rapidly, and plastic trimming should be paid attention to during the growth period to promote the growth of lateral branches and to produce more flowers. Trim times - generally 1 to 3 times, which should not be too much, otherwise it will affect the number of flowering. After each flowering, remove the remaining flowers in time to reduce nutrient consumption. After the flowering period to the dense branches, inner chamber branches, long branches, weak branches for sparse pruning, on other branches - like not pruning or only on the branches for a little pruning, and should not be heavy cut, in order to shorten the growth of the round, promote its early flowering, many flowering.

Pay attention to light and ventilation

The Great Bougainvillea is a positive plant. In order to make the branches and leaves grow normally and increase the number of flowering, the Great Bougainvillea must be placed in a well-lit and well-ventilated position, and it must be illuminated for 8 to 12 hours a day. Frequent shading will lead to barren growth and a decrease in the number of flowers. If the location is not ventilated or placed between the basin and the basin is too close, it will make the leaves fall off, especially in hot summer, suddenly hot and suddenly rain, easy to cause a large area of leaves fall off, thus affecting the growth and flowering of the plant.

Strengthening pest control

The most common pests in Great Bougainvillea are leaf beetles and aphids, and the most common diseases are shoot dieback. Usually to strengthen soil weeding, timely removal of dead branches, diseased leaves, pay attention to ventilation, in order to reduce the spread of the disease source. Strengthen the examination of the condition, found that the condition is handled in time. We can use dioate, tobujin to prevent.
