How to care for gardenia
This article introduces how to care for gardenias and the indoor gardening methods related to gardenia care, with detailed information provided below.
Suitable soil: Use fertile, loose, slightly acidic soil for cultivation, and change the soil once a year.
Adequate light: expose to scattered light, and promptly shield from strong sunlight, as lack of light can affect flowering.
Appropriate temperature: maintain temperature between 15-28°C, and pay attention to low temperatures in winter to prevent frost damage.
Proper watering: Water frequently during the growing season to keep the soil moist, and strictly control water after winter, watering only when necessary.
Reasonable fertilization: Apply thin fertilizers frequently during the spring germination period and before flowering to promote growth and flowering.
I. Suitable soil
Large-leaf gardenias require high-quality soil, preferably loose, breathable, fertile, and slightly acidic, as this allows the roots to breathe better and absorb nutrients, leading to vigorous growth. When preparing the soil, it is best to mix garden soil with leaf mold, river sand, and base fertilizer, and ensure that the soil is disinfected before use to prevent the presence of eggs. Additionally, it is best to change the soil every spring for potted plants to prevent soil compaction and excessive alkalinity.
II. Adequate light
Large-leaf gardenias enjoy light and have a slight tolerance for shade but do not tolerate direct sunlight. To promote vigorous growth and better flowering, they should be placed in a bright area with plenty of scattered light to facilitate photosynthesis. In the summer, when sunlight is too strong, shading measures must be taken to prevent sunburn. If kept in a shaded environment for an extended period, they may exhibit poor growth, with spindly branches and leaves, and even affect flowering.
III. Appropriate temperature
The ideal temperature for the growth and flowering of large-leaf gardenias is between 15-28°C. They thrive in warm environments and have poor cold tolerance. In high summer temperatures, as long as there is good ventilation, they can safely survive. In winter, with low temperatures, especially in northern regions, measures to control temperature and keep warm must be taken. It is best to move them to a warm room, maintaining temperatures above 8°C to prevent frostbite and ensure safe overwintering.
IV. Proper watering
Large-leaf gardenias prefer a moist environment, especially during the growing season when their water demand is high. It is best to water frequently to keep the soil slightly moist but avoid waterlogging. During continuous rainy weather, watering can be paused, and excess water should be drained promptly to improve ventilation. After entering winter, their growth essentially stops, and strict water control is necessary, watering only when the soil is dry, as slightly drier soil is actually better for overwintering.
V. Reasonable fertilization
Large-flowered gardenias consume a lot of nutrients during growth. Starting from spring germination, it is necessary to apply diluted organic fertilizer or nitrogen fertilizer solutions frequently to promote the growth of branches and leaves. Before flowering, apply more phosphorus and potassium fertilizers, and stop fertilizing after flowering to avoid shortening the blooming period. Note that raw fertilizers or fertilizers with high concentrations should not be applied to avoid fertilizer damage.
