Year-round Management Methods for Gardenia
Main text introduction: This article discusses the related aspects of year-round management methods for Gardenia. Read on as the editor provides a detailed explanation.
1. Spring Management
When the flower and leaf buds of Gardenia have not yet germinated (March in the south, April in the north), it is time to transplant and repot. For Gardenia that has been potted for 2-3 years, or when the roots extend out of the pot's drainage hole, repotting is necessary. When repotting, mix the soil with a ratio of 4:4:2 of horse manure, garden soil, and river sand, and add a tablespoon of alum or sulfur powder, and apply hoof slices or crushed bones, decomposed soybean cakes, or chicken manure (25 grams) as a base fertilizer. For those transplanted into the ground, sufficient base fertilizer should also be applied.
Water thoroughly and create a windless semi-shaded environment. After a week, it can fully receive sunlight. Water every three days to keep the soil moist but avoid waterlogging, and frequently spray water on the leaves and ground. When Gardenia is budding, windbreak measures should be taken during windy days.
For watering Gardenia throughout the year, it is best to use rainwater and fermented rice washing water.
2. Summer Management
If the cultivation environment of Gardenia is not improved during hot sun, high temperatures, and heavy rain, it may cause yellowing leaves and eventual death. Therefore, during the hot season, attention should be paid to ventilation and shading, and water should be sprayed on the leaves and ground in the morning and evening to cool down, and accumulated water should be drained after rain.
Starting from late May, apply a thin liquid fertilizer once a week, and during this period, switch to using alum fertilizer water once, and for mature plants, add some sesame seed cake. In the north, to prevent iron deficiency in the plants, sprinkle some ferrous sulfate (black vitriol) on the soil surface every half month to keep the branches and leaves dark green.
For 1-2-year-old seedlings, prune and shape them from May to July, cutting off the top shoots to form a three-branch structure. After 2-3 years of cultivation and pruning, a more aesthetically pleasing hemispherical crown can be formed. Summer is the blooming season; after the flowers fade, remove them promptly to promote a more abundant blooming in the next period.
In hot and dry areas, be sure to water adequately to prevent the plants from wilting and drying out.
3. Autumn Management
Stop applying fertilizer in mid-September and reduce watering. Once the hot season is over, remove the shading to allow the plants to receive ample sunlight.
4. Winter Management
From Cold Dew to before Frost Descends, when the night temperature drops to 0°C, water thoroughly to prevent freezing. In the south, potted Gardenias can be placed outside in a windless, sunny spot to survive the winter safely, while in the north, they need to be moved indoors in a sunny spot. The ideal overwintering temperature is between 0-10°C. Lower temperatures may cause freezing, and higher temperatures are not conducive to overwintering. During the overwintering period, potted Gardenias should be controlled for watering, only watering when necessary, about once every 4-7 days. However, leaves should be frequently sprayed with water to prevent dust accumulation. In the following April, when the temperature stabilizes at 10°C, move them outdoors. This concludes the introduction to the year-round management methods for Gardenia.
