Is gardenia afraid of cold in winter?

Although gardenia is not afraid of cold in winter, the limit temperature is-12 degrees, but when it is maintained, it should be adjusted to the temperature suitable for its growth, and the growth temperature should be kept at about 5 degrees, so that it can survive the winter smoothly.

The south can be farmed outdoors, and the north needs to move into the house for protection. If it is a plant planted outdoors, it is necessary to take anti-freezing measures before the arrival of cold air. You can wrap the trunk with waste cotton wool or the whole plant with plastic.

Its leaves will not fall and turn yellow in autumn and winter, but if the light can't meet its needs, its metabolism will not be completed normally, and the leaves will fall and turn yellow. In winter, you should receive at least four hours of sunshine every day. If possible, it is best to put it in a sunny place, which is beneficial to photosynthesis.

growing environment

Like light, it can resist yin. In the shade, the leaves are dark green, but the flowers are a little poor. I like warm and humid climate, heat-resistant and a little cold-resistant (-3℃), fertile, well-drained and acidic light clay loam, and drought and barren resistance, but plants are easy to age. Strong resistance to sulfur dioxide. Strong tillering ability and germination ability, resistant to pruning and regeneration.
