Light requirements in detail

Dieffenbachia prefers medium indirect (5000–15000 lux) . Tolerates low light but grows leggy; bright indirect keeps the variegation crisp

A spot 1–2 meters from a bright east or south-facing window usually fits this range. Direct afternoon sun through unfiltered glass can scorch leaves; sheer curtains help diffuse it.

Watering in detail

Water Dieffenbachia every 7– 10 days during the growing season, allowing Top 2-3cm of soil to dry between waterings. Reduce frequency in winter when growth slows.

Consistent moisture matters here — long dry spells will show up as crispy leaf edges.
