Aglaonema modestum Chinese Evergreen1
Edward F. Gilman2
Introduction
Easily grown, the attractive plants eventually form substantial clumps of green stems with 10 to 14-inch-long, shiny, deep green leaves (Figure 1). This lends a tropical characteristic to any shaded area planted with Chinese Evergreen. The plant requires shade making it well-suited to low light conditions for house plants or sheltered, outdoor northern exposures. Temperatures below 45°F can injure the foliage.

Use and Management
Any fertile, nematode-free soil or artificial media is suitable for growth, yet Aglaonemas will survive in peat and perlite, in sand, or can be grown hydroponically. They enjoy moist soil which is allowed to dry slightly before watering. Be careful not to overwater but do not let the soil dry for more than a few days. Aglaonemas require shade since direct sun will turn leaves yellow. They perform admirably in conditions too dark for most other tropicals. They will succeed in low light, either as house plants or in sheltered locations on the north side of buildings, or under heavy shade of trees. They are attractive planted as single specimens, or in mass to create a tropical, coarse-textured effect. Plant on two- to three-foot centers. Temperatures below 45°F. can injure the foliage. Overwatering causes root rot and yellowing of the leaves.
Propagation is by cuttings.
Soil-borne nematodes and mites can be a problem for Chinese Evergreen.
Pests and Diseases
No pests or diseases are of major concern. Roots can rot if the soil is kept too wet.
