Cultivation and care tips
Dieffenbachias thrive in bright, indirect light. They need warm (18-23°C), humid conditions. To prevent root rot, use a pot with drainage holes and add a drainage layer to the bottom, such as clay or gravel. Plant in nutrient-rich, well-drained soil. Repot in spring if the roots outgrow the container.
Irrigation: Water when the top 2 inches of soil is dry. Mist the leaves to increase humidity, especially in hot, dry areas.
Fertilize every two weeks from March to September. Use a high-quality liquid fertilizer. It is not possible to remove the adverb. But you can remove old or discolored leaves for a cleaner look. If the plant looks thin, root pruning favors new growth.

Common problems and solutions
Root rot: caused by overwatering, resulting in soft, dark roots and yellow or brown leaf tips. Replant immediately in fresh, dry soil if in doubt.
Leaf spot: A fungal problem that causes brown or black spots. Remove affected leaves and use a fungicide.
Spider mite: Webs and light spots on the leaves indicate the presence of spider mites. Treat with neem oil or insecticidal soap.
Mealybugs: these seed-sucking insects can weaken the plant. Treat with neem oil or a soapy water solution. They multiply.
Propagation of dieffenbachia is easy. Take cuttings (part of the stem with 2 to 3 leaves) and put them in water or soil. You can also cut a 5 cm section of the trunk, place it in moist soil, and cover it with plastic film to keep moisture.
Security Council
Dieffenbachias are toxic if ingested, so keep out of reach of children and pets. Always wear gloves when handling the plant, as the juice can irritate the skin.
