As summer approaches, many Sedum sarmentosum plants begin to lose their leaves. This phenomenon not only affects the ornamental value of the plant but can also have adverse effects on its growth. This article will analyze the reasons for leaf drop in Sedum sarmentosum during summer and provide corresponding care tips to help your plant get through the hot season.
Reasons for Leaf Drop in Sedum sarmentosum in Summer1. Climatic Factors
High summer temperatures, intense sunlight, and dry air can cause the leaves of Sedum sarmentosum to lose water too quickly, leading to dryness and shedding.
2. Improper Watering
In summer, Sedum sarmentosum has a high demand for water. However, both overwatering and underwatering can cause leaf drop. Overwatering leads to root hypoxia, while underwatering causes leaf dehydration, which in turn triggers leaf shedding.

Both excessive and insufficient fertilization can affect the growth of Sedum sarmentosum. Too much fertilizer can lead to high soil salinity, damaging the plant's roots and causing leaf drop. Too little fertilizer can result in malnutrition, slow growth, and gradual wilting of the leaves.
4. Pest and Disease Infestation
The hot and humid conditions of summer are conducive to the breeding of pests and diseases. Infestations can damage the leaves of Sedum sarmentosum, leading to leaf drop.
