Rattlesnake plant care guideCalathea lancifolia
Wavy spotted leaves. Ranked #32 of Europe's most-searched houseplants.
WateringWhen and how much water
Water Rattlesnake plant when the top 2 to 3 cm of soil feel dry to the touch. In summer that's typically every 7 to 10 days; in winter slow down to every 14 to 21 days. Use room-temperature water and let any excess drain — never leave the pot sitting in standing water.
The real schedule depends on three things the calendar can't see: the actual light at the plant, the pot's size and material (terracotta dries faster than glazed ceramic), and your local humidity. Botanicaly's app retunes the schedule from those signals on every reminder.
LightHow bright a spot it needs
Rattlesnake plant is medium / indirect light: thrives in bright, indirect light. Direct midday sun can scorch the leaves. The ideal lux range is 2,000 - 10,000 lux. In practical terms, place it 1-2 metres back from an east or west window, or behind a sheer curtain on a south window.
