Humidity guide
How much humidity does four-angled cassiope need?
What actually works
If tips do start browning, group four-angled cassiope with other plants or move it away from radiators and draughts. A pebble tray helps a little; a small humidifier helps a lot. Neither is needed unless the plant is telling you it is dry.
Why misting is not the answer
Treating four-angled cassiope as a tropical diva. Over-humidifying a plant in this middle band, especially in a cool room with little airflow, causes more mould and rot problems than dry air ever would.
