Aglaonema Pictum Tricolor plant prefers a well-draining, fertile, and slightly acidic soil. A mix of peat moss, perlite, and well-aged compost is an excellent choice for these plants. The soil should be moist but not waterlogged, as too much water can lead to root rot. Additionally, it is recommended to fertilize the plant every two to three months during the growing season to provide the essential nutrients required for healthy growth.
