Watering and feeding
Over or under watering, changing temperatures and droughty positions are the main causes of leaf browning and drop. Avoid overwatering, and allow the surface of the compost to dry beofre appplying addition water. Apply water at room temperature. Allow excess water to drain away, and do not let the plant sit in water. In the winter months, reduce the watering quantities until the compost is dry between watering, unless the plant is continuing to grow vigorously or is in flower. Never employ overhead watering with these types of plants. Water directly onto the compost or into the draining saucer.
