Bougainvillea is a kind of flower in the south. When it blooms, it is very gorgeous and the flowering period is quite long. In the process of maintenance, irregular pruning is needed. Prevent the branches from growing white, keep a relatively compact shape, and help them bloom. Bougainvillea grows very fast, and many flower lovers like to use large pots of flowers, so bougainvillea grows very tall.

The bougainvillea has grown taller. Can you cut it from the pole into a single-edged bald head?

It is possible to dwarf bougainvillea when it grows into a slender stem, but it is necessary to find the right time and see the growth of the tree before dwarfing and cutting it down. Otherwise, the cut bud position may not be ideal, and the whole plant may die. Pay attention to the following three points when cutting bougainvillea twigs:

I. Cutting time:

When cutting bougainvillea, suggestions can be made in spring or autumn. The spring cutting time is slightly close to that of Tomb-Sweeping Day, and the temperature is stable above 22 degrees Celsius. It is best to cut it dry in late summer and early autumn, and pay attention to lowering the temperature below 32 degrees Celsius. When the temperature is slightly higher, you need shade. The seasonal temperature varies greatly from place to place, so? Season is secondary, and temperature is dominant? )

Second, the preparation before cutting:

The cutting time of bougainvillea is suitable, and the bougainvillea should be fertilized before cutting. What is the main purpose of fertilization? Nitrogen? Fat. Irrigation with urea and water about 600 times. After a week of fertilization, control the water for 3 to 5 days, and let the leaves droop slightly before cutting. Fertilization can promote germination, and it should be carried out before the fertilizer is absorbed. )

III. Interception operation:

When cutting dry, move bougainvillea to a bright place to avoid strong light. Select the position of the stem, and cut the stem with branches (it is best to have side branches at the selected position to prevent the branches from shrinking after cutting). The wound should be trimmed and leveled with a utility knife, and the wound should be coated with a wound healing agent to prevent rainwater from invading the wound and becoming moldy. At the same time, it promotes wound healing. It's rainy in spring, so you can wrap a plastic bag to prevent getting wet. Dry in autumn, wrapped in plastic bags, can keep moisture. )

Four, maintenance after cutting:

1, bougainvillea bougainvillea should be watered immediately after being cut, and the branches should be wetted with water 3 ~ 5 times a day. Be careful not to wet the wound when spraying.

2, put it in a bright and ventilated place for a week, and then you can move the basin to a position with astigmatism. Avoid strong light at noon, and it is best to have about 3 hours of light in the morning or evening.

3. About 15 days after the stem is inserted, bougainvillea can grow new buds after the fertilizer effect is exerted before the stem is inserted. In the later stage, all fertilization was changed to organic fertilizer with balanced nutrients. Make thin fertilizer, apply it frequently, 1 twice a month.

4. After the bougainvillea is cut, the new buds grow to about 20 cm, and the buds can be pulled into horizontal growth by pulling. In the later stage, the crown area can be enlarged and more flowers will bloom.

Summary: bougainvillea grows faster. If it grows into a tall and thin rod, you can choose to cut it at the right time. The truncation operation can refer to the above method. Generally, after 1 month management, you can enter the vigorous growth period or flowering period without delaying flowering.
