Bougainvillea is usually pruned in spring, because the plant has resumed growth, so it can promote the development of new growth. Usually, new branches are pruned in a short-cut manner, cutting off one-third or half of them, and the cut should be close to the buds, which can stimulate their growth. Old branches need to be reduced, retaining weak branches is more helpful for flowering, and retaining strong branches is conducive to rejuvenation. In addition, it should be appropriately thinned to increase internal ventilation and light transmission.

1. Pruning time

1. Pruning time

Pruning of bougainvillea is best done in spring, when the plant begins to grow. Pruning is more conducive to recovery, and can also reduce nutrient consumption, which is helpful for plant flowering. If you prune too late, it will delay its growth, thus affecting plant development.

2. Pruning method

1. Short pruning: If the bougainvillea grows slowly, short pruning can be used to stimulate the development of new shoots. This method is generally aimed at new branches, and is divided into light pruning and heavy pruning. Light pruning should cut off about one-third, and heavy pruning should cut off half. Usually, the cut should be close to the bud, so the stimulation effect is better. In addition, short pruning can prevent the mother branches from thickening.

2. Thinning: If there are too many bougainvillea Dense, intersecting branches block ventilation and light transmission, are not conducive to internal growth, and pose a risk of pests and diseases, so they need to be thinned out. This method mainly involves cutting off dense branches and overlapping branches so that the inside can receive light and have good air circulation. Also remove weak branches to promote plant growth.

3. Pruning: If the old branches of bougainvillea do not bloom very much, you should consider pruning them. Shrinking pruning generally retains weak branches. If strong branches are retained, they will have a rejuvenation effect but will not bloom. However, weak branches are different. They do not consume much nutrients themselves, so they have enough nutrients to help bloom. In addition, shrinkage cutting cannot be done all at once, but must be done several times.

3. Post-cut maintenance

< p>After pruning the bougainvillea, apply carbendazim on the wound to prevent it from being infected with bacteria and causing it to become sick. At the same time, attention should be paid to fertilizing to supplement nutrients for new growth.
