The culture soil was a mixture of slightly acidic sandy laterite and leaf saprolite. It is advisable to control the pH value of the soil between 4.0 and 6.5.

The temperature

Therefore, it is advisable to conserve Cape Jasmine in the open forest or shade shade with good ventilation, high air humidity and transparent light in summer.

Cape Jasmine

Moisture

Cape Jasmine likes humid air, and water should be added moderately during the growing season. Usually the basin soil can be white water, thoroughly pouring. Summer is hot, every day to foliar spray 2-3 times, in order to increase air humidity, help plants cool down. But after the flower is bud, watering should not be too much, so as not to cause falling bud.Winter watering with partial dry had better, prevent water root rot.

Fertilizer

Cape Jasmine is a fat-loving plant. In order to meet its growing needs and maintain a slightly acidic soil, Ferric Sulphate can be mixed into the fertilizer solution for fermentation. After entering the growth season in April, we can apply  top dressing every half a month (fertilization when it is best to add some water, in case of burning). This will not only meet Cape Jasmine's needs for fertilizer, but also keep the soil in a relatively balanced acidic environment to prevent the occurrence of chlorosis, as well as avoid the damage to Cape Jasmine caused by accidental ferrous sulfate supplement and local excessive acid.

Disease control in Cape Jasmine

Cape Jasmine is frequently prone to leaf yellowing and leaf spot, which is sprayed 600 times with 65% Zinc WP. The insect pests were acanthophora moth, scale insect and mealworms. The acanthophora moth was sprayed with 2.5% enemy killing emulsion 3000 times, and the scale insect and mealworms were sprayed with 40% oxidized dimethoate emulsion 1500 times. 

Yellowing disease

The occurrence is more common, caused by a variety of reasons. It is necessary to take different measures to prevent and control the general application of decayed human excrement or cake fertilizer.

Young leaves between the veins of the loss of green and yellow, seriously will make the whole plant leaves yellow, and even coke leaves and branches withered, and finally cause the plant death. In this kind of situation, we can spray 0.2% ~ 0.5% ferrous sulfate aqueous solution for prevention and control. The chlorosis caused by magnesium deficiency gradually develops from the old leaves to the new leaves, and the veins are still green. In severe cases, the leaves fall off and die. In this kind of situation, we can spray 0.7%, 0.8% boron magnesium fertilizer prevention and control. Overwatering, freezing and so on, will also cause the phenomenon of yellow leaves, so in the maintenance process to pay special attention to. The appearance of nitrogen deficiency is simple yellow leaves, and the new leaves are small and crisp. Potassium deficiency appears as the green to brown color of old leaves. Phosphorus deficiency is manifested as purplish red or dark red in old leaves.
