How to grow gardenia? The latest cultivation methods and precautions
Gardenia, also known as yellow gardenia, is an evergreen shrub. It has luxuriant branches and leaves, stays evergreen all year round, and its flowers are fragrant when they bloom, making it most suitable as an ornamental plant for courtyards. So how should we grow it? What precautions are there during the cultivation process? Follow the Qinnong website editor below to take a look at the cultivation methods and precautions for gardenia.
1. Soil
Before planting, choose a soil it can adapt to, so that it can grow well. Gardenia prefers fertile, loose, well-drained acidic soil. The most suitable soil pH is between 4-6. You can also make a potting mix by blending leaf mold with garden soil and peat soil.
2. Light
Gardenia prefers an environment with ample light. Especially during vigorous growth, it has a relatively high demand for light. If there is insufficient light, its branches and leaves will become thin and weak, and the flowering period will be prolonged or flowering will be difficult. In spring and autumn, the duration of light needs to be increased, while in summer, when temperatures are high and sunlight is intense, we should shade it or move it indoors for cultivation to avoid withered branches and leaves caused by harsh sunlight.
3. Temperature
Gardenia prefers a warm environment. The optimal growing temperature is 16-18 degrees. Temperatures that are too high or too low are both detrimental to its growth. Therefore, in the high-temperature summer season, measures should be taken to lower the temperature of the growing environment, and in the low-temperature winter season, warmth must be provided. In both summer and winter, you can choose an indoor environment with good ventilation for cultivation.
4. Water
Gardenia prefers a humid environment and has relatively high requirements for both soil moisture and air humidity. During the growing season, ensure a sufficient water supply and water frequently. At the same time, you can spray water mist on the leaves or in the growing environment to increase air humidity. In winter, pay attention to the amount of watering to avoid excessive water accumulation causing root rot.
5. Fertilizing
Its demand for nutrients is moderate. It is recommended that during the peak growing season, apply fertilizer once every two weeks. This is beneficial for the growth of its branches and leaves, and afterward it will bloom more and more abundantly.
Precautions
1. Pruning
During the growth period of gardenia, the branches tend to overlap, which is not conducive to ventilation, so it should be pruned appropriately. Only in this way can it grow better and promote branching. After the flowers fade, promptly cut off the remaining branches, which can both preserve nutrients and promote the sprouting of new shoots.
2. Pests and diseases
The main diseases of gardenia are leaf yellowing and leaf spot. Leaf yellowing is generally due to a lack of nutrients in the plant. When discovered, fertilizer should be applied in time to supplement nutrients. For leaf spot, 65% zineb wettable powder can be sprayed at a 600-fold dilution. The main insect pests are stinging caterpillars, scale insects, and whiteflies, which can be killed by purchasing insecticides and spraying them.
