Many flower enthusiasts enjoy growing gardenias, and I am very fond of them too, especially because the fragrance of gardenia flowers is particularly delightful. I also have two pots of gardenias at home, and right now it is the season when gardenias bloom, which is very beautiful. And the large-leaf gardenia looks gorgeous just from its leaves alone. However, if gardenias are not cared for properly, they are also prone to various diseases. Here, Xiaonong will chat with everyone about gardenias.

1. What happened to the flower enthusiast's gardenia?

Judging from the pictures provided by the flower enthusiast, the gardenia's overall growth condition is still quite good, but the leaves are covered with small yellow-white flying insects. From the pictures, the flower enthusiast's gardenia should have whitefly. And the situation is not looking good.

2. What kind of pest is whitefly?

Friends who often grow flowers should be familiar with whitefly. Whitefly is a kind of flying small yellow-white moth. Its harm to flowers and plants is very serious. Whitefly mainly sucks plant stem sap, causing poor plant growth, and can cause fungal infections in plants, and in severe cases cause plant death. So it must be dealt with promptly.

3. How to deal with whitefly?

From the pictures, the whitefly on the flower enthusiast's gardenia should not have been present for very long, but the number of whiteflies is still quite large. The flower enthusiast must deal with it promptly, otherwise it can easily cause the gardenia not to bloom, poor growth, and other problems.

The flower enthusiast can use a 90% trichlorfon 800-1000 times solution to spray the leaves. When spraying, be careful to also spray the backs of the leaves with the solution. Do it once every week, and generally the pest can be brought under control in about a month.

Some flower enthusiasts live in apartment buildings and grow gardenias on balconies, so it is not suitable to spray pesticide. In this case, the flower enthusiast can use mosquito coils (a little method recommended by some flower enthusiasts), cover the gardenia with a bag, light a mosquito coil inside, and fumigate the insects with the mosquito coil. Fumigating for about one hour is enough. In daily life, a few sticky insect boards can be placed on the balcony, which can reduce flying insect damage.

In daily care, pay attention to keeping the gardenia's growing environment ventilated and airy. More airflow can reduce the number of flying insects.
