Why does the bougainvillea leaf produce sugar? What should I do if the bougainvillea leaf produces sugar?

Bougainvillea, also known as Bougainvillea glabra, is the city flower of Guangzhou. It is generally planted more in southern my country, and in the north it is mainly potted. It has many flowers and bright colors, and is also suitable for daily planting. Sometimes you will find sticky things on the leaves, which is usually caused by insect pests.

Why do bougainvillea leaves produce sugar?

The sugar secreted by bougainvillea leaves is mainly caused by the secretions of aphids.

Aphids infect many plants and secrete a kind of nectar from their tails while sucking plant sap. This is the main reason why bougainvillea leaves produce sugar.

If this phenomenon occurs in bougainvillea, it is necessary to use drugs to control it in time to kill aphids, otherwise it is easy for bougainvillea to be infected with various bacteria and fungi, affecting the growth of bougainvillea. At the same time, fungicides should be used for prevention.

Bougainvillea grows very fast and has very good disease resistance, but if it lacks management or the planting environment is not suitable, it is very susceptible to diseases and pests.

What to do if the leaves of bougainvillea produce sugar

aphid

In drought conditions, aphids are prone to appearing in bougainvillea, and aphids are also prone to appearing in high temperature and high humidity environments.

To treat aphids on bougainvillea, you need to move it outdoors and place it in a well-ventilated environment for spraying. Usually, we can use imidacloprid diluted and sprayed for treatment. However, you can also treat it at home without using pesticides. That is, mash the garlic and take its juice, then add water at a ratio of 1:10 for treatment, and the effect is also very good.

Scale insects

When bougainvillea is growing, it is prone to scale insects. After the scale insects bite the leaves, leaf gum will appear, which looks like sugar to us.

If the cause of the sugar on the leaves of bougainvillea is scale insects, we can use scale insect spray to treat it, or we can go to the flower market to buy Baichongling for treatment, because Baichongling does little harm to bougainvillea and humans, and the price is only 1 to 2 yuan.

Why are the leaves of bougainvillea wrinkled?

Fertilizer damage

If you apply too much or too concentrated fertilizer, or if you use organic fertilizer that is not fully decomposed, it will cause fertilizer to burn the roots, resulting in uneven and wrinkled leaves. At this time, remove the pot, wash the roots, and spray brassinolide to alleviate the problem.

Pests

Piercing-sucking pests such as thrips or aphids that absorb leaf juice may also cause leaf curling and deformity, which usually appears on the young buds of the leaves, and you can carefully observe the leaves to find insect bodies, eggs or excrement. If it can be determined to be a pest, you need to use sprays such as imidacloprid and omethoate to prevent and control it.

Overwatering

Excessive watering will cause the roots to be unable to carry out aerobic respiration, resulting in poor growth and development, and the leaves may also become wrinkled.

In addition, lack of light will also cause the leaves of Bougainvillea to be unable to fully photosynthesize, causing them to become wrinkled and unable to expand.
