How to care for and manage large gardenias
The editor introduces you to how to care for and manage large gardenias and the tips for growing large gardenias in terms of plant knowledge. Next, the editor will provide you with detailed answers.
Suitable soil: Cultivate with fertile, soft, slightly acidic soil, and change the soil once a year.
Adequate lighting: Get plenty of scattered light, and promptly block strong light, as lack of light will affect flowering.
Appropriate temperature: Control the temperature between 15-28°C, and pay attention to low temperatures in winter to avoid frostbite.
Proper watering: Water frequently during the growing season to keep the soil moist, and strictly control water after entering winter, only watering when dry.
Reasonable fertilization: Apply thin fertilizer frequently during the spring germination period and before flowering to promote growth and flowering.
I. Suitable soil
Large-leaf gardenias have high requirements for soil. The soil used should be loose, breathable, fertile, and slightly acidic, as this allows the roots to breathe better and absorb nutrients, thus growing vigorously. When mixing soil, it is best to mix garden soil with leaf mold, river sand, and base fertilizer, and the prepared soil must be disinfected before use to prevent the presence of eggs. Moreover, it is best to change the soil once a year during spring for potted plants to prevent soil compaction and excessive alkalinity.
II. Adequate lighting
Large-leaf gardenias enjoy sunlight and have a slight tolerance for shade but are not resistant to strong sunlight. To make them grow vigorously and bloom better, it is best to place them in a bright area with plenty of scattered light to promote better photosynthesis. In summer, the sunlight is too strong, and shading measures must be taken to promptly block strong light and avoid sunburn. If kept in a shaded environment for a long time, it may lead to poor growth, with limbs easily becoming elongated, and even affecting flowering.
III. Appropriate temperature
The temperature conducive to the growth and flowering of large-leaf gardenias is between 15-28°C. They prefer a warm environment and have poor cold resistance. In high summer temperatures, as long as ventilation is ensured, they can safely survive. In winter, with low temperatures, especially in the north, it is necessary to take temperature control and warming measures. It is best to move it to a warm room and keep it above 8°C to avoid frostbite and ensure safe overwintering.
IV. Proper watering
Large-leaf gardenias prefer a moist environment, especially during the growing season, when their demand for water is high. It is best to water frequently to keep the soil slightly moist but avoid waterlogging. If it rains continuously, you can pause watering, and for outdoor cultivation, it is necessary to promptly drain accumulated water and enhance ventilation. After entering winter, its growth basically stops, and strict water control is necessary, only watering when dry, as slightly drier soil is actually better for overwintering.
V. Reasonable fertilization
Large gardenias consume a lot of nutrients during growth. Starting from spring, it is necessary to apply diluted organic fertilizer or nitrogenous fertilizer solutions frequently to promote the germination of branches and leaves. Apply more phosphorus and potassium fertilizers before flowering, and stop fertilizing after flowering, as otherwise, it will shorten the blooming period. Note that you must not apply raw fertilizers or fertilizers with high concentrations to avoid fertilizer damage.
