Keep Dieffenbachia in a warm, humid environment to replicate its tropical origins. Mist the leaves occasionally or use a pebble tray with water to increase humidity. Rotate the pot weekly to ensure even light exposure and prevent the plant from leaning. Clean the leaves regularly with a damp cloth to remove dust and keep its bold patterns bright and healthy. With proper care, this eye-catching plant will thrive as a stunning indoor feature.

Water Dieffenbachia consistently, keeping the soil evenly moist but never soggy. Allow the top 2–3 cm of soil to dry slightly between waterings to avoid overwatering, which can cause root rot. During the growing season, water more frequently, but reduce this in winter when growth slows. Always use lukewarm, filtered water, as this plant is sensitive to cold temperatures and chemicals in tap water.

To plant Dieffenbachia, select a pot with drainage holes and fill it with a nutrient-rich, well-draining potting mix, such as one designed for houseplants. Position the plant so its root ball sits level with the surface, ensuring the base of the stem is not buried. Backfill gently with soil, firm lightly, and water thoroughly to settle the roots. Place the pot in a spot with bright, indirect light to help maintain its vibrant foliage.
