Your Schefflera may be dropping leaves due to sudden changes in its environment. Plants are sensitive to shifts in light, temperature, or humidity. If you recently moved the plant to a new location, it might be reacting to lower light levels or drafts. Scheffleras prefer bright, indirect light and stable temperatures between 60-75°F (15-24°C). A sudden drop in humidity, especially in winter, can also cause leaf loss as the plant struggles to retain moisture.
Improper watering is a common culprit for leaf drop. Scheffleras dislike soggy soil, which can lead to root rot and subsequent leaf shedding. Check the soil: if it’s consistently wet or smells musty, you’re overwatering. On the other hand, underwatering causes the plant to conserve resources by dropping leaves. The soil should dry slightly between waterings but never become bone dry. Adjust your watering schedule based on the season—less in winter, more in summer.
Even with careful watering, poor drainage can mimic overwatering symptoms. If the pot lacks drainage holes or the soil is compacted, roots suffocate and rot. Scheffleras thrive in well-draining, aerated soil mixes. Repotting into a container with drainage holes and fresh, peat-based potting mix can help resolve this issue. Additionally, salt buildup from fertilizers or tap water can stress the plant, leading to leaf drop. Flush the soil occasionally to remove excess salts.
Pests like spider mites, scale, or mealybugs can cause sudden leaf loss. These tiny invaders suck sap from the leaves, weakening the plant. Inspect the undersides of leaves and stems for webbing, sticky residue, or tiny insects. Treat infestations promptly with insecticidal soap or neem oil, and isolate the plant to prevent spreading. Regular wiping of leaves with a damp cloth can also deter pests.
Scheffleras need balanced nutrients to maintain healthy foliage. A lack of nitrogen, for example, can cause older leaves to yellow and drop. Conversely, overfertilizing can burn roots and trigger leaf loss. Use a diluted, balanced fertilizer every 4-6 weeks during the growing season (spring to summer) and avoid fertilizing in winter when growth slows. Always follow package instructions to prevent nutrient imbalances.
Some leaf drop is normal as Scheffleras shed older leaves to focus energy on new growth. However, sudden or excessive loss indicates stress. If only the lower leaves are yellowing and falling, it might just be natural aging. But if multiple leaves drop at once or the plant appears leggy, investigate other potential causes listed above.
Scheffleras dislike sudden temperature fluctuations. Cold drafts from windows, air conditioning, or heating vents can shock the plant, causing leaves to drop. Similarly, exposure to extreme heat (like near radiators) can dehydrate the foliage. Keep the plant away from vents and maintain a consistent room temperature to prevent stress-related leaf loss.
If you recently repotted your Schefflera, it might experience transplant shock. Disturbing the roots can temporarily stress the plant, leading to leaf drop. Ensure the new pot is only slightly larger than the old one, and water the plant gently after repotting to help it settle. Avoid fertilizing for a few weeks to allow recovery.
