Heather can be a finicky plant indoors, but with some care, you can keep it happy. Aim to provide it with bright, indirect light; a spot near a window with a sheer curtain might work well. Heather prefers slightly acidic soil, so you may want to consider adding some peat to its potting mix if it seems unhappy. In terms of watering, they like it consistently moist but well-drained—so water thoroughly and let it dry slightly between waterings. Watch for signs of stress like wilting or browning, which could indicate too much or too little water. Remember, these plants naturally thrive in cooler, damp environments, so avoid letting the room get too dry or hot. A small humidifier nearby can help maintain the right atmosphere.
