Does Gardenia Like Sunlight?
Gardenia is a type of flower that thrives in abundant sunlight, requiring ample light for photosynthesis. Especially during spring and autumn, when gardenias are in their growing phase, they need a significant amount of sunlight. Although gardenias enjoy sunlight, they should be protected from direct exposure during the summer due to the intensity of the sun.
Does Gardenia Enjoy Sunbathing?
Gardenias appreciate sunlight but can tolerate some shade, and they are averse to strong direct sunlight. In the summer, many gardenias can get sunburned on their branches and leaves.
In particular, gardenias that have been maintained in semi-shaded conditions for an extended period can easily get their leaves scorched and develop burn spots if suddenly placed in strong direct sunlight, which can lead to severe withering of branches and leaves.
In spring, autumn, and winter, gardenias can be kept in the sunlight, which is beneficial for their growth and prevents the sprawling of branches and leaves.
As summer approaches and sunlight intensifies, it is crucial to move them to a location with diffused light to prevent damage and sunburn on the branches and leaves.
How to Care for Gardenias for Optimal Growth
Gardenias grow well in the south because they are typically acid-loving plants. In the north, soil and water tend to be alkaline, which often results in iron deficiency chlorosis.
To care for them properly, it is necessary to use loose and fertile acidic soil. Moreover, every 1 to 2 years, when the nutrients in the soil become scarce, it is essential to repot and change the soil to ensure there is an adequate supply of nutrients.
When cultivating gardenias, it is advisable to use more soil rich in humus, such as loose and breathable pine needle soil or other decomposed leaf soils.
If using ordinary garden soil, it is recommended to mix in a lot of decomposed organic matter, such as sheep manure or chicken manure, to increase the fertility of the growing medium.
Gardenias are very fond of fertilizer, and when the nutrients in the potting soil become scarce, the leaves will show obvious yellowing, and the plant will not easily grow new branches and leaves or bloom. Therefore, frequent fertilization throughout the plant's growing period is a key factor for vigorous growth.
Firstly, a ferrous sulfate water-soluble fertilizer should be used at least once a month because gardenias are prone to iron deficiency chlorosis. If the nutrients in the potting soil are insufficient, the leaves will turn yellow and lose their vitality.
To avoid this issue, it's best to use ferrous sulfate fertilizer once a month, diluted in water at a ratio of 1:1000, and apply it directly to the roots.
During the growing period, fertilizers containing other elements should also be supplemented regularly, with a compound fertilizer applied every two weeks or so.
