What is going on with the geranium leaves turning brown at the edges and falling off?
Abstract: This article discusses why geranium leaves turn brown at the edges and fall off, as well as related topics about the cultivation and management of geraniums. If there are any mistakes, please feel free to correct them!
Excessive sun exposure: In summer, without proper shading, strong sunlight can scorch the plants.剪掉焦叶并做好遮光措施可搬到室内凉爽的位置 Cut off the scorched leaves and take shading measures, then move them to a cool indoor location.
Fertilizer burn: After applying fresh or concentrated fertilizer, fertilizer damage can cause the leaves to turn brown at the edges. You can dilute the fertilizer in the soil by watering, and watering should continue until water flows out from the bottom of the pot.
High temperature: It is not heat-tolerant. If the cultivation temperature is too high, the leaves will become crispy and dry. It is necessary to cool down promptly or move it to a shaded area under trees.
I. Excessive sun exposure
Reason: Geraniums that are cultivated outdoors for a long time may not have proper shading measures in place after summer. The strong sunlight at noon in summer can scorch the leaves.
Solution: There is no good solution after being sunburned. You can only provide shading for it promptly and cut off the wilted parts to avoid continuous water loss. When caring for it later, be sure to move it indoors when the sun is strong at noon in summer.
II. Fertilizer burn
Reason: Although geraniums enjoy fertilizer, too much at once is not good. If you apply thick or fresh fertilizer, a large amount of fertilizer can cause it to dehydrate, similar to a person consuming too much salt. After fertilizer-induced dehydration, the leaves will show brown edges.
Solution: If it is caused by excessive fertilization, it is recommended to water it more, which can dilute some of the fertilizer in the soil and alleviate the symptoms of fertilizer damage. Watering should continue until a large amount of water flows out from the bottom of the pot.
III. High temperature
Reason: Geraniums do not like environments that are too hot, especially in summer. If they grow in a high-temperature environment for a long time, the edges of the leaves will become dry and crispy.
Solution: Take prompt measures to cool down, such as moving it to a cool and shaded indoor area or to a shaded outdoor spot under trees. To cool it down quickly, you can also spray water on it with a spray bottle.
