What to do if the leaves of gardenias dry up and fall off
Today's sharing: How to deal with the drying and falling of gardenia leaves and knowledge about gardenia cultivation methods and watering plants, the following is a detailed introduction.
Gardenias have a strong fragrance when they bloom, and their leaves are large and thick, making them very popular among gardeners. They are typical southern flowers and may encounter various problems when grown in the north, the most obvious being the yellowing and falling of their leaves. What causes this? The yellowing and falling of their leaves usually start from the bottom, with one leaf after another turning yellow and then falling off, which can be divided into two situations.
The first situation is when the old leaves of gardenias that have been grown for a long time turn yellow and fall off. The main reason for this is a lack of fertilizer. When fertilizer is deficient, the bottom leaves will turn yellow and fall off in large numbers. Insufficient watering can also cause this, so it is important to water gardenias regularly. The principle is to water thoroughly when the soil surface is dry, as gardenias love water. Ensure there is no lack of water, and fertilize regularly to prevent yellowing and leaf drop. If you have been growing gardenias for a long time and this happens, check if the potting soil is compacted and whether there is a lack of water. If there is a lack of water, supplement it, and if the potting soil is compacted, change the soil.
The second situation is when the bottom leaves of gardenias turn yellow and fall off in large numbers after repotting. This is most likely to happen immediately after repotting because the roots may be damaged and have not yet grown new ones. The plant cannot get enough water, so the bottom leaves start to turn yellow and eventually fall off. In this case, you must help the plant adapt to its new pot.
This process, known as "hardening off," involves placing the plant in a well-ventilated area and keeping the potting soil moist without letting it dry out. Water thoroughly when the soil surface is slightly dry, provide some scattered sunlight, and spray the leaves with a fine mist three times a day (morning, afternoon, and evening) to help them absorb water. Since the roots are damaged, their ability to absorb nutrients and water is reduced, so we need to help the leaves absorb water by spraying them, preventing yellowing and leaf drop, as well as wilting. This is the most common situation after repotting. Follow the advice of Xiaoqi to spray the leaves with water to alleviate the situation. Initially, some leaves may fall off, but as the roots grow, the yellowing and leaf drop will decrease.
If gardenias experience yellowing and falling leaves, the main reasons are these two. If only one or two leaves fall off occasionally, this is normal leaf aging and does not require intervention. If severe yellowing and leaf drop occur as described in the two situations above, it is due to these reasons. Analyze your cultivation situation accordingly.
