The Aglaonema Pictum Tricolor can be multiplied through stem cuttings or division. To propagate through stem cuttings, follow these steps: 1. Select a healthy stem with at least two leaves and cut it at a 45-degree angle using a clean, sharp knife. 2. Remove the lower leaves from the stem, leaving only two or three leaves on the top. 3. Dip the cut end of the stem in rooting hormone to encourage root growth. 4. Plant the stem cutting in a pot filled with well-draining potting soil. 5. Water the cutting and keep it moist, but not waterlogged. 6. Place the pot in a warm, bright area, but not in direct sunlight. 7. After a few weeks, roots should start to form, and the cutting will begin to grow new leaves. To propagate through division, follow these steps: 1. Carefully remove the plant from its pot and gently separate the roots into two or more sections. 2. Pot each new section into a separate pot with well-draining potting soil. 3. Water the new plants and keep them moist, but not waterlogged. 4. Place the pots in a warm, bright area, but not in direct sunlight. 5. After a few weeks, new leaves should begin to grow, and the plants will start to establish themselves.
