Finding out why the leaves of the jasmine gardenia turn black and fall

Why do the leaves of the jasmine gardenia turn black and fall and what to do about it
The reason for leaf fall in gardenia can be:
- sunburn;
- a sharp drop in the temperature of the content;
- excess or lack of moisture;
- damage by pests.
What to do with a burned gardenia
Like any flowering culture, gardenia is demanding on lighting and will not tie buds in the shade. At the same time, keep in mind that direct rays are deadly for her. Delicate leaves darken before the eyes, becoming covered with dry spots, and fall off. There is no way to restore them, so make sure that the remaining foliage is not damaged.
Carefully remove the blackened leaves and move the pot to a darkened place.
What is the connection between the temperature in the room and leaf fall
Gardenia loves not only light, but also warmth. Although its relatives grow well outdoors in the fresh air, this variety needs stable positive values. The optimum temperature for keeping indoor gardenia should not fall below 18 ° C. Otherwise, blackening and fall of foliage is inevitable. Urgently move the bush to a warm room, where there should be no draft.
Improper watering as a cause of foliage falling
With a lack of moisture, everything is clear: in overdried soil, gardenia simply begins to dry out. You can restore it by giving plenty of "drink", best of all through the pallet.Spraying the crown will not interfere, but moisture should not get on the buds, if any.
But if the flower is constantly flooded, the roots begin to suffer and rot. They can no longer provide the aboveground part with adequate nutrition. Gardenia can only be saved by a complete replacement of the soil, provided that not all the roots have rotted. Otherwise, there will be only a chance to cuttings.
What pests attack gardenia
The spider mite loves the flower most of all. He bites through the leaf plate, drinks the juice and it dries up. It is almost impossible to see the insect without a magnifying glass, but the web on the back of the leaves "gives out" it. Remove them immediately, wash the bush with soapy water and treat with an insecticide, otherwise the tick will move to the rest of the indoor plants. Drugs such as Actellic, Akarin, Fitoverm.
