Although gardenia has a graceful posture, white and fragrant flowers, and is very popular with people, many flower enthusiasts say that it is not easy to care for. During the maintenance process, it often easily develops rotting roots and yellow leaves, especially when the weather gets hot in summer, the leaves turn yellow and fall off for no reason. In fact, if you take care of it in four aspects, you can avoid yellow leaves and make the leaves become greasy and glossy.
Avoid direct sunlight
Gardenia is a positive flower that likes to grow in a sunlit environment. Letting it get more sunlight can help it set buds and bloom, and also make the leaves greener and more glossy. However, gardenia is also afraid of strong sunlight. When the temperature reaches above 35℃ in summer, you should consider shading it. If you continue to expose it to the sun, the leaves can easily get sunburned and turn yellow and fall off. For gardenia in bloom, it can easily burn the flowers and shorten the flowering period.
Therefore, when caring for gardenia, it is necessary to provide appropriate care according to the actual situation in different seasons. For example, gardenia that has not been exposed to sunlight for a long time has tender leaves, and if it is suddenly moved to the sun, it can easily cause yellow leaves due to a sudden change in the care environment. It is best to first place it in a place with scattered light and gradually let it adapt to a sunny environment.
Do not let it become too dry
Gardenia should not be short of water in summer. It is a plant that loves water and is known as "water gardenia."加上 this season's high temperatures and strong sunlight, water evaporates very quickly. If watering is not timely, the plant will not be able to absorb water from the potting soil, and the leaves will turn yellow and fall off.
In summer, watering gardenia must be timely, especially for gardenia under the sun. If it lacks water, it can easily get sunburned, so watering should be frequent. Water the potting soil thoroughly when it is dry, and when the environment is relatively dry, also spray water around the plant to cool and increase humidity, providing a good growing environment.

Do not apply excessive fertilizer
In summer, gardenia is in its growing season and can be fertilized as long as the temperature is not too high. However, you should also pay attention when fertilizing. Do not apply too much fertilizer at once or apply some raw fertilizer that has not been fermented in the flowerpot. Excessive or too much raw organic fertilizer can easily burn the plant's roots, causing rotting roots, yellow leaves, and even the whole plant can turn yellow and wither.
For gardenia potted plants that have finished flowering in summer, you can apply some dilute compound fertilizer or well-fermented organic fertilizers such as chicken manure or sheep manure. Usually, you can also water it with fermented rice washing water or fruit peel water to adjust the soil pH.
Supplement ferrous sulfate
Gardenia is a typical acidic flower. If it is not repotted or fertilized for a long time, or if the soil becomes alkaline, it is prone to iron deficiency yellow leaves. This type of yellow leaves is different from ordinary yellow leaves. The veins are green, and the rest of the leaf surface is light yellow. This type of yellow leaves is mainly caused by a lack of nutrients.
When caring for acidic flowers like gardenia, you should keep some ferrous sulfate fertilizer at home and regularly supplement it with iron to adjust the soil acidity. While fertilizing it, water it with a 1:1000 ferrous sulfate water solution once a month, and slowly its leaves will become greasy and glossy.
In summer, various yellow leaf phenomena of gardenia are mostly caused by the above reasons. As long as you do well in these points during daily maintenance, you can avoid the yellowing and falling leaves of gardenia.
