Soil

Big-leaf gardenia has strict requirements on soil, and the pH of the soil must be between 5-6. However, the soil in the north is alkaline or neutral. In this kind of soil, iron salts are difficult to dissolve in water and cannot be absorbed by plants, causing iron deficiency in plants. Iron deficiency will block the synthesis of green leaves, hinder photosynthesis, and cause plant death. Therefore, suitable soil is important. Watering black alum water once every 10-15 days during the growing period can also ensure the iron requirements of gardenias.

Humidity

Big-leaf gardenia likes a humid environment. Keep the pot soil moist and increase the air humidity appropriately. The north is dry in spring with long northwest winds, strong sunlight and rapid water evaporation in summer, and cold and dry winters. Therefore, in spring and summer, more water should be sprayed on the leaves and on the surrounding ground to increase air humidity. Water less in winter and spray the branches and leaves frequently to keep the leaves clean.

Light

Large leaves Gardenia likes light, but is afraid of strong light. If exposed to strong light, the leaves will turn yellow, white and fall off. Especially in summer, it should be maintained on a covered balcony or in a place with scattered light. It can be moved to the sun in the morning and evening to receive light to prevent the leaves from turning yellow.

Temperature

Unlike small potted varieties, large-leaf gardenias have poor cold tolerance and should be moved indoors for maintenance in winter. Usually, it is moved indoors in mid-October and placed on a sunny and well-ventilated balcony to maintain the room temperature at 10~12℃. Moved outdoors in late April of the next year.

Flower maintenance is not difficult, if you do it From the above four points, large-leaved gardenias can not only make a home in the north, but also have green leaves and flowers and are full of fragrance.
