Reasons Why Gardenia Flowers Turn Yellow and How to Fix It

Flowers & Gardening 0 views
The most likely reason gardenia flowers turn yellow is a lack of water, so you should give them a bit more water. Another cause is too much light. This not only makes the leaves droop from sun exposure, but the flowers may also turn yellow. Normally, just two hours of light a day is enough. In addition, there is another possibility: the flowers are about to fade. Because this plant differs from other kinds, its flowers also turn yellow when they are close to fading.

1. Water problems

(1) Specific cause: This issue is more common in the north, and it comes down to a lack of water. This plant loves water very much. If the flowers start to turn yellow, it may be that the water supply is too lacking.

(2) Solution: Increase the amount of water appropriately. If that still does not work, you can take the following approach. Simply put, soak it in water for half an hour to an hour each day. Put the whole plant, pot and all, into a bucket, or a large water basin will do as well. This allows the water to fully penetrate into the flower soil. After that, take it out and let the water drain off. Then place it in a shady spot to grow. Besides this, you can also mist it with water every day. Of course, if there is rain, it can also be left out in it for a while.

2. Light problems

(1) Specific cause: Receiving light for too long not only affects the leaves, but may also make the flowers turn yellow.

(2) Solution: No light at all is certainly not workable, but too much is equally bad. Generally speaking, even when it is flowering, about two hours a day is enough. This is because this plant is shade-loving, and even when flowering it does not need much light.

3. A normal phenomenon

Sometimes it is not a problem with our care, but simply normal. This plant is a bit different: at first the flowers are milky white, then they may gradually turn yellow, and then wither. In other words, turning yellow is a sign that they are about to fade. So there is no need to take any remedial measures.
