A few days ago, I went to the wild to look for flowers, and found that bougainvillea could grow and blossom without manual management, marveling at how strong its vitality is. However, in the case of hot summer and dry autumn climate, if the maintenance method is improper, it is easy to be possessed by insects. In fact, as long as the bug is solved in time, it will not cause serious harm.
Next, let's save bougainvillea that was hurt by insects.
First of all, put an end to insects: for bougainvillea, there are two common pests, moths and scale insects.
Moths will have a pair of flying wings when they grow up, and there will be a layer of powdery substance outside their bodies, which will not only harm the current plants, but also fly to other plants to reproduce for the next time; Before growing up, it grows on the back of leaves, mainly absorbing juice to maintain life; Leaves curl and turn yellow, and fall off in severe cases.
Scale insects look like hard-shelled melon seeds, mainly lurking on twigs and leaves. Because the absorbed thorn is not so hard, it can only stay in the most tender tissue. If not handled in time, it will breed into a dense mass, leading to the withering of the whole plant.
Secondly, spraying water "eliminates".
Although scale insects and moths are not a kind of pests, they can be sprayed with 2.5% dichlorvos EC, but they need to be mixed with 5000 times of water according to the instructions. In fact, we can kill worms visible to the naked eye by artificial means, but in order to prevent eggs from growing again, we need to spray chemicals thoroughly to prevent them.
Spraying water has a strong smell, so it is best to do it outdoors to avoid polluting indoor air; At the same time, air circulation is beneficial to the recovery of plants.
Finally, the maintenance after illness determines the speed of recovery.
First, the light should be sufficient, which not only satisfies the growth habit of bougainvillea, but also has the function of sterilization again. Second, it is necessary to properly water the soil to ensure that it is moist, and to avoid water wetness and water accumulation. Third, stop fertilization and maintenance, and wait until the growth resumes, and then carry out reasonable fertilization.
Generally speaking, when bugs are found in bougainvillea plants, they must be pruned and sprayed with chemicals in time to eliminate the source of bugs, and finally the plants can be restored to health after scientific and reasonable maintenance.
