What to do if the leaves of gardenia turn yellow

When the gardenia blooms, it has a pleasant fragrance and is white and beautiful, which is welcomed by many families. So what should we do if we find its leaves turn yellow during cultivation? First, we need to find out the cause of the yellowing, and then stop watering it. We should also do maintenance work such as shielding the plant from strong light, diluting fertilizer, and strengthening ventilation to allow the plant to recover quickly.

1. Stop watering

Gardenia cannot tolerate waterlogging. If you water it frequently or too much at one time during its growth, it will easily accumulate water and the leaves will begin to turn yellow. Excessive water needs to be drained in time, and then the plant should be removed from the pot and placed in a cool and ventilated place to dry, and then repotted for maintenance.

2. Block out strong light

When it is too hot in summer, do not expose the plant to the sun, otherwise it will cause burns and the leaves will turn yellow. Move it to a cool place with scattered light for recovery. When new leaves grow green, it means it has returned to normal.

3. Dilute fertilizer

If you find that the veins of the leaves are yellow, but the surrounding area is still green, it is probably caused by over-fertilization. At this time, you should stop fertilizing and dilute it with plenty of clean water to drain the excess fertilizer from the drainage holes. If the situation is too serious, you can directly change the pot.

4. Improve ventilation

Many gardenias grown at home will have yellow leaves. This is mainly because the indoor ventilation is insufficient and the air is not circulating. It is recommended to open the doors and windows for ventilation every day so that the plants can absorb fresh air and the yellow leaves will disappear soon.

How to grow gardenia

According to the growth habits of gardenia, a loose, fertile, breathable and well-drained slightly acidic soil environment is most suitable for the growth of gardenia. Therefore, leaf mold or peat soil is chosen as the growing soil for gardenia.

Gardenia likes a warm and humid environment. Although it can grow in semi-shade, it still needs to be guaranteed to have about four to five hours of sunshine a day, but it must avoid direct sunlight. It is best to grow it in the morning or afternoon when the sunlight is weak so that it can carry out sufficient photosynthesis.

In summer, when the weather is hot, the gardenia needs to be watered frequently, once or twice a day, as soon as the surface of the pot soil is dry. In the evening, the leaves evaporate more water, so you can use a watering can to wet the leaves to ensure sufficient humidity.

Gardenia is not a flower that relies heavily on fertilizer. In spring and summer, you can apply appropriate fertilizer once every half a month. When the temperature reaches below 15 degrees Celsius in autumn, you can stop fertilizing and let it gradually enter a dormant state. In winter, pay attention to the insulation and ventilation of gardenia to ensure its flowering state next year.

Gardenia Flowering Period

Generally speaking, the flowering period of gardenia is from April to August every year. Due to the differences between the north and the south, the gardenias in different places will be slightly different due to various factors such as climate and geographical environment. In the south, they basically bloom in April every year, while in the north, they bloom in June.

In addition, its flowering time is also closely related to maintenance. If watering, fertilization, ventilation, etc. are proper, the flowers will slowly wither by the end of August. If maintenance is not appropriate, it may only bloom in June and July.

Different varieties of gardenias bloom different numbers of times each year. No matter how you care for the large-leaf gardenia, it will only bloom once a year. If the small-leaf gardenia is properly cared for, it can bloom twice a year. The four-season gardenia can also bloom twice a year.

During the flowering period of gardenia, it is necessary to manage the water well. If the weather is hot, you can water it more and spray water around the plant to increase the humidity. Be careful not to sprinkle water directly on the petals, otherwise it will easily cause premature withering.
