What are the breeding methods and precautions of gardenia in spring?

The optimum temperature for gardenia growth is 20 ~ 28%, and the weather is hot in late spring and early autumn. Pay attention to shade, prevent high temperature and direct sunlight, and speed up air circulation, otherwise the leaves will turn yellow easily.

Gardenia planted in the field should be transplanted in March-April with clods. There is plenty of sunshine in late spring and early autumn, so it is necessary to properly spray water to cool and humidify. Potted gardenias can overwinter in the open air in the south.

The Huanghuai river basin was moved into the greenhouse in mid-June of 10, and the room temperature was kept at 5 ~ 12℃. If it exceeds 15℃, it will affect dormancy and growth in the coming year. In winter, it should be placed in a place with abundant sunshine, good air circulation and suitable temperature.

Pay attention to control watering and dry it. The lower the temperature, the less watering, so the concentration of somatic cells will increase, which is beneficial to resist the cold. Low temperature or too wet pot soil is easy to cause defoliation and even death.

Gardenia should be watered wet and dry. Too wet soil leads to the death of roots due to hypoxia and suffocation, and yellow leaves appear on the ground, especially after gardenia buds appear, so the watering amount should be controlled.

Generally, water should be poured 1 time every 2 ~ 3 days in spring and autumn, 1 ~ 2 times in summer and 1 time in winter for 5 ~ 7 days. In addition, applying 1 times alum fertilizer every half month in summer, and spraying water on the leaves frequently to remove dust is beneficial to plant growth.
