Humidity guide
How much humidity does blue lyme grass need?
What actually works
If tips do start browning, group blue lyme grass 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 blue lyme grass 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.
