Amount of Light, Watering, and Fertilization Needed
This Moss doesn’t particularly enjoy the warmth and will need to be protected from the intense sun rays of warmer climate zones. Absorbing filtered light is essential for maintaining its brilliant green color. Plant your Irish Moss in partial or full sun or for the best results.
Water Irish Moss regularly, at least weekly, and provide it with more water during the hotter days. Keep the soil damp, but not wet. It does not perform well in drought conditions.
You can fertilize this perennial but do so sparingly. If it receives too much nitrogen, it may reduce the amount that its new growth spreads, resulting in a mounded appearance.
