Most propagation of "Aglaonema" is done with cuttings and by dividing the basal shoots. Care of the houseplant involves protecting it from cold temperatures and excessive sunlight and removing any inflorescences that develop, which can prolong the life of the plant. It requires moist soil, and while some cultivars require a small amount of fertilizer, plants are easily injured when oversupplemented. "Aglaonema" are prone to false mites ("Brevipalpus californicus"). They may also acquire populations of nematodes, such as root-knot nematodes and "Pratylenchus" species, which cause root lesions. Pathogens include the fungus "Myrothecium roridum" and bacteria such as "Pseudomonas cichorii", "Erwinia chrysanthemi", and "Xanthomonas campestris", which can all cause leaf spot. "Colletotrichum" fungi can cause anthracnose.
