Dieffenbachia Care Guide

Dieffenbachia, also known as Dumb Cane, is a bold and beautiful tropical plant known for its large, patterned leaves and upright habit. With its lush, leafy presence and tolerance for lower light, it's a fantastic statement plant for homes and offices. This guide covers everything you need to know to help your Dieffenbachia thrive.

Plant Profile

Dieffenbachia Light requirements

Dieffenbachia does best in bright, indirect light. It can tolerate lower light, but the leaf patterns may fade. Avoid direct sunlight, which can burn the foliage. A few feet back from a sunny window or a bright spot with sheer curtains is ideal.

Dieffenbachia Watering

Allow the top 3–5cm of soil to dry between waterings. Dieffenbachia prefers lightly moist conditions but is sensitive to overwatering. Always check that the pot has proper drainage, and reduce watering in the colder months. Yellowing lower leaves often signal too much water.

Dieffenbachia Repotting

Repot every 1–2 years in spring using a well-draining, peat-free houseplant compost with added perlite or bark. Dieffenbachia can grow quite large over time, so choose a stable pot and only increase pot size gradually.

Dieffenbachia Native habitat

Dieffenbachia is native to the tropical rainforests of Central and South America. In the wild, it grows under the forest canopy, thriving in warm, humid, shaded conditions—perfectly suited to indoor life away from direct sun.

Styling ideas for Dieffenbachia

With their large, decorative leaves and upright form, Dieffenbachia adds drama to corners, entryways, or office spaces. Pair with a bold ceramic pot or natural-toned planter to highlight the foliage. They make excellent stand-alone features or work well alongside finer-leaved companions for contrast.
