Don't overwater. Don't underwater. Add some predator mites. Turn up the lights. Enjoy. The Ming is not the easiest plant to keep happy, but this plant makes a real statement. Available in a 10 inch pot at around 5 feet and in a 14 inch container at around 5.5 feet.
The meters below indicate a range of light and tolerance to drought. The ranges are indicated by the little light bulbs and the small water drops.
Mites should be primarily controlled with predator mites. Neoseiulus californicus,(Spical, Spical Plus, Californiline) and Phytoseiulus persimilis,(Spidex, Bio Persimilis, Phytoline) are two excellent choices for spider mite control. If a mite infestation is exceptionally bad, prior to the release of predator mites, spray the plant with water or horticultural oil. Both will provide some knockdown control of spider mites and will not leave a toxic residue that may effect predator mites. Miticides registered for interior use and compatible with predator mites include Sultan, Shuttle O and Floramite SC.
Mealybugs can be removed with a systemic insecticide drench and hand cleaning. If pesticides are not an option, try horticultural oil directly sprayed onto the insects. A second and third treatment, if using oils, will be necessary. Space out the sprays at 3 week intervals to break up the mealybug life cycle.
Aphids can be controlled with the same treatment as mealybugs.
Ming Aralia seems to have more problems with disease in the nursery compared to the other aralias. If Mings are being kept in a warm humid environment with other plants try to keep the foliage dry to prevent disease. Moving air will help dry the dense canopy of a Ming Aralia and may prevent disease.
To recuperate an Aralia that has lost too many leaves, trim each small stem about 2 inches from the woody cane, fertilize and place in a higher light environment.
