Too much or too little water plus insects and mites are the main problems. Mealybugs, scale insects and mites are common pests of scheffleras. Root rot usually results from a soil mix that does not drain quickly or overly frequent watering. Dead areas form on leaves several days after exposure to excessive cold. Maintain temperatures above 50 F. Do not place plants near air conditioning vents.
Low light can cause leaf yellowing with spindly, weak stems.
Leaf drop can be caused by excessive watering, by low humidity, or by chilling. Water scheffleras thoroughly, then let the soil dry to inch deep before watering again. Never let a plant sit with water in its saucer. Scheffleras prefer day temperatures between 65 and 75 F. Nighttime temperatures should remain above 60 F. Keep plants away from heat vents, radiators, open windows and air conditioners. Hot or cold drafts will damage plants.
