1, lighting

Gardenia likes to grow in a sunny environment, so it keeps the plants illuminated for 7-9 hours every day. Note that it can be placed indoors in a cool and ventilated place when the light is strong in summer. In autumn and winter rainy season, put it in a bright position.

2. Temperature

Gardenia likes to grow in a warmer environment, and the most suitable growth temperature is between 16-25 degrees. When the temperature is below 0 degrees, keep warm and put it in a sunny room, covered with plastic film. When the temperature is higher than 35 degrees, transfer to a cool and ventilated environment and spray wet water to reduce the temperature.

water

Gardenia has a high demand for water and likes humid environment. Therefore, in the growing season of spring, summer and autumn, to ensure the moist environment of the basin soil, water can be poured once every two days, so it is not necessary to water it in the rainy season. Be careful not to accumulate water every time watering, and the water temperature should be appropriate when watering in winter to avoid freezing the plants.

Matters needing attention in gardenia cultivation

1, Gardenia likes being fat, but is afraid of being fat. Generally, cake fertilizer containing more phosphorus and potassium should be applied twice before germination and stopped after germination. If fertilizer is applied too much, the roots will burn easily and the buds will fall off easily. Apply 1 decomposed cake fertilizer water or manure water every half month during the growth period, and add 1% ~ 2% ferrous sulfate to prevent soil alkalization.

2. Gardenia likes half shade and is afraid of direct light. The shading requirement is about 50%. If exposed to the sun, the leaves will turn yellow and white until they fall off, so in summer, they should be placed in the cool place where farting or light is scattered. Let it see the light in the morning and evening to avoid yellowing of the leaves.
