Three reasons you must know about yellowing gardenia leaves, treating the symptoms correctly is the best solution
Many people enjoy growing gardenias, but it is common for the leaves to turn yellow and fall off when kept at home. What causes this, and how should it be prevented and treated?
Actually, the first reason for yellowing gardenia leaves is due to the alkalinity of the potting soil. Gardenias are flowers from the south and prefer acidic soil. When growing them at home, it's best to keep the soil acidic by adding some well-fermented pine needles to the soil. Regularly watering with iron sulfate, once a month or every two months, can also prevent new leaves from turning yellow except for the green veins. This is the best solution.
The second situation is when the lower leaves turn yellow and fall off in large numbers. The main reason for this is a lack of fertilizer. Especially when gardenias are blooming, many gardeners stop fertilizing or do not supplement fertilizer during the care process, or even grow them in garden soil, leading to nutrient deficiencies, which can cause the lower leaves to turn yellow and fall off. During both the growing and blooming seasons, fertilizers are essential. In general, a balanced multi-element fertilizer, such as a multi-element nutrient solution or compound fertilizer, with a low concentration, should be used once every two to three months. As the blooming season approaches, that is, after entering spring, start using phosphorus-potassium fertilizers, ensuring an adequate supply of phosphorus and potassium to prevent yellowing leaves.
The third situation is due to improper watering. Gardenias love water, and many gardeners water them excessively. If the soil is not dry before watering, it can lead to poor indoor ventilation and soil accumulation, causing some roots to rot. Some root rot, accompanied by the lower leaves turning yellow in large numbers, or even the top new leaves turning black and drying, is a situation caused by excessive watering. If you are short of water for a long time, the leaves will wilt, and they can recover after watering, but the lower leaves will also turn yellow and fall off. If this continues, the entire plant will dry up and die. Therefore, when growing gardenias, it is important to control watering. Generally, the soil should be well-draining, and the pot should not be too large. The watering principle is to water thoroughly when the soil surface is dry, and this will not cause any problems.
When growing gardenias at home, the leaves turning yellow, drying, and falling off are the most common reasons. Analyzing your situation accordingly will not cause any problems. When growing gardenias, it is important to choose a pot of the appropriate size and not too deep. Water it when the soil surface is dry and keep it in a well-ventilated area with plenty of sunlight. Don't let the fertilizer be missing. This way, the gardenias we grow will be able to grow and bloom normally without any problems.
