Dieffenbachia ‘Big Ben Variegata’ – Care Guide

Light

Prefers bright, indirect light to maintain vivid variegation. Tolerates moderate light but avoid direct sunlight, which may scorch the leaves.

Watering

Water when the top 3–5 cm of soil feels dry. Keep soil lightly moist but never waterlogged, as Dieffenbachia is prone to root rot. Reduce watering in winter when growth slows.

Temperature and Humidity

• Temperature: Best kept between 18–28°C. Avoid draughts and cold below 15°C.

• Humidity: Prefers moderate to high humidity (50–70%). Mist occasionally or place near other plants to maintain moisture around the leaves.

Soil and Potting

Use a rich, free-draining peat-free houseplant compost mixed with perlite or orchid bark for aeration. Repot every 1–2 years in spring to refresh soil and encourage growth.

Feeding

Feed every 4–6 weeks during spring and summer with a balanced liquid fertiliser. Pause feeding during winter.

Pruning and Maintenance

Remove yellowing or damaged leaves at the base to promote fresh growth. Rotate the pot occasionally to maintain even shape and prevent leaning towards the light.
