Why do the leaves of the star flower pineapple turn yellow
Today, the editor will introduce the reasons why the leaves of the star flower pineapple turn yellow and share some experience about the maintenance of green plants, including the maintenance steps of pineapple flowers. Next, our site editor will introduce to everyone.
Pineapple flowers are also known as ornamental pineapple, bromeliad, etc., and are native to the jungles from Mexico to southern Brazil and northern Argentina. They are quite famous festival flowers. Many flower enthusiasts find that the leaves of their pineapple plants turn yellow after buying them and keeping them for a while, but they don't know what's wrong with the pineapple. Let's take a look at what to do when the leaves of pineapple flowers turn yellow.
Overwatering
Overwatering can lead to long-term excessive moisture in the potting soil, causing soil hypoxia, rotting of some fibrous roots, and hindering normal respiration and absorption of water and nutrients, resulting in yellowing and falling off of leaves. Initially, the young leaves turn light yellow, followed by the old leaves gradually turning yellow. You should immediately control watering, stop fertilizing, and frequently loosen the soil to ensure good soil aeration.
Drought and dehydration
Forgetting to water the plants or long-term watering only halfway up the pot (i.e., wet on top and dry at the bottom) can affect nutrient absorption and easily cause the leaves to become dull and lose their luster, leading to wilted and drooping leaves. Initially, the lower old leaves age and gradually turn yellow and fall off from the bottom up. At this point, a small amount of watering and spraying is needed to gradually restore the plant before returning to normal watering.

Long-term lack of fertilizer
Long-term absence of nitrogenous fertilizer or not changing the potting soil can lead to a lack of nutritional elements in the soil, causing the branches and leaves to become weak, with thin and yellow leaves. It is necessary to repot and replace the old soil with new, loose, and fertile potting soil, gradually increasing the application of thin, decomposed liquid fertilizer or compound flower fertilizer.
Over-fertilization
Too much fertilizer can cause new leaves to become thick and uneven, with old leaves drying up,尖焦黄脱落. You should immediately stop fertilizing, increase watering, and allow the fertilizer to flow out from the bottom of the pot, or repot and rinse the root ball with water before replanting it in the pot.
High heat
In summer, if you place heat-sensitive flowers (such as cyclamen, fuchsia, and kalanchoe) in a high-temperature area exposed to direct sunlight, it can easily cause the young leaves to have burnt leaf tips and edges or turn yellow and fall off. It is necessary to move them to a well-ventilated, shady place.
