Keeping a heather plant indoors can be a bit challenging, but it's definitely possible with the right care. They love bright, indirect light, so positioning near a sunny window is ideal. Watering is key—keep the soil consistently moist, but ensure good drainage to prevent root rot. They prefer cooler temperatures, so try to avoid placing them near heaters or vents. Watch out for signs of stress like browning, which can indicate issues with watering or humidity levels. A little extra humidity from a pebble tray can help as well!
