What about fortune-telling flower tree worm _ flower tree worm?

If the situation of osmanthus leaves is not terrible, if we can stay, remove pests and diseases, properly trim and shape, and strengthen fertilizer and water management, it is easy to restore the vitality of trees.

If the terminal branch is too weak, you can consider shortening and rejuvenating. But if there are no leaves, it is best to cut off all the tiny weak branches and leave a basic skeleton, so as to recover quickly. Because there are no leaves, we can't afford to grow too many bare branches. Cut them short, they will recover quickly, and the new branches will be strong. Pay attention to water and fertilizer management after short cutting.

Finally, I want to say that aphids are small green lice that cluster around twigs and secrete sugary mucus. Starscream, people with poor eyesight can't see it. If you have a good eye, look carefully at the yellow, white and mottled corners on the back of the leaves bitten by the red spider, and you will find some crawling little red dot. If you wipe it with your hands, you will see red marks on your hands and leaves. Generally, you can tell whether there are many red spiders by the leaves, or whether they have eaten and run away. Osmanthus fragrans is an evergreen tree and the favorite host of Starscream. Just as there are mites on people's faces, red spiders are mites on osmanthus trees. If there are many mites, the surface of the leaves will be rough and dull, and the whole tree will look weak and its growth will be greatly affected, because the chlorophyll has been eaten by the red spider. But well managed and pruned osmanthus trees will greatly reduce the number of red spiders. )
