Analysis of the reasons for the dropping of Phalaenopsis leaves and care suggestions

Reasons for Phalaenopsis Leaf Drop and Care SuggestionsPhalaenopsis leaf drop reasons1. Insufficient lightingPhalaenopsis is native to tropical rainforests and prefers a semi-shaded environment. If lighting is insufficient, it can lead to slow growth of Phalaenopsis, thin leaves, and eventually leaf drop. When caring for Phalaenopsis, it should be placed in a place with plenty of scattered light.2. Improper wateringPhalaenopsis is not tolerant of waterlogging. Excessive watering can cause root rot, which in turn affects leaf growth. Insufficient watering can also cause leaves to lose water, leading to dry and fallen leaves. When watering, the principle of "dry and wet" should be mastered to avoid water accumulation.3. Uncomfortable temperatureThe suitable growth temperature for Phalaenopsis is between 18°C and 28°C. Too high or too low temperatures can cause leaves to fall. In high summer temperatures, appropriate shading should be provided, and in low winter temperatures, warmth should be noted.4. Improper application of fertilizerExcessive application of fertilizer can damage the roots of Phalaenopsis, thereby affecting leaf growth. Improper fertilization can also cause symptoms such as leaf spots and yellowing. When fertilizing, the principle of "fertilizing less frequently" should be followed, and special fertilizers suitable for Phalaenopsis should be chosen.5. Pest and disease infestationPests and diseases are one of the important causes of Phalaenopsis leaf drop. Common pests and diseases include leaf spot disease, root rot disease, and red spider mites. Once pests and diseases are found, measures should be taken promptly for control.Phalaenopsis leaf drop care suggestions1.
