1. Chlorosis

There are many factors causing chlorosis, and the more common ones are these three factors: magnesium deficiency, iron deficiency and nitrogen deficiency, which are caused by different factors, different forms of manifestations and different prevention and treatment.

The yellow leaves shown by magnesium deficiency start with the old leaves and slowly spread to the new leaves, but the veins are green, and when they are more serious, they continue to cause defoliation. When this happens, you can spray 0.7% Mel 0.8% boron and magnesium fertilizer on the branches and leaves to supplement magnesium. The yellow leaves shown by iron deficiency start with the new leaves and turn yellow. In serious cases, they will scorch the withered branches of the leaves, and even lead to the death of the whole plant. In this case, 0.2%-0.5% ferrous sulfate can be sprayed on the branches and leaves to supplement iron. The yellow leaves shown by nitrogen deficiency are only simple yellow leaves, and the new leaves are atrophied and do not grow up. In this case, some flower friends stop applying nitrogen fertilizer in order to blossom and prevent them from growing.

2. Soot disease

Soot disease is mainly followed by insect pests, after some pests gnaw on the branches and leaves, secrete honeydew and some excrement left on the branches and leaves, the symptom is the formation of black mildew spots on the leaves and branches, and then expand, so that the whole leaves and shoots are covered with black mold layer, causing plant death.

When there are pests on the gardenia, attention should be paid. After killing the pests, the branches and leaves should be checked, washed with clean water, and then sprayed with diluted carbendazim. In the early stage of the disease, 0.3 Baume stone sulfur mixture can be sprayed to treat the disease.

3. Rot disease

Most of the rot disease is caused by improper watering, old branches and diseased branches are not treated in time, and often occurs on the lower trunk, the symptoms are shown in the expansion and cracking of the stem, when this situation is found, it should be immediately coated with 5-20 degree stone-sulfur mixture. then move it to a cool and bright ventilated place, prune and disinfect the old and diseased branches in time.
