WateringWhen and how much water

Water Sweetheart plant when the soil has dried out completely. In summer that's typically every 14 to 21 days; in winter slow down to every 30 to 45 days, sometimes less. 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

Sweetheart plant is bright / direct light: needs several hours of direct sun. Turn the pot every week so it grows evenly. The ideal lux range is 10,000 - 50,000 lux. In practical terms, place it directly in front of a south or southwest window, or 30 cm from an east window.
