1. no fertilizers have ever been used
2. the black moss is only in my indoor pots, under lights
3. the moss is always moist, never wet. Always plenty of moisture..
Browning and blackening of the crowns or tips is usually results from excessive evaporation which wicks the dissolved ions to the surface (mostly Calcium). Rinse with pure water and gently rub the moss with your hands until the crust dissolves and rinses away. Warm water might help. Warm, not hot unless you want cooked moss.
Browning like this most commonly occurs with moss exposed to strong sunlight and wind.
Sphagnum moss will voraciously absorb any nutrients. Tip browning could also be an indication of excessive nutrients from peat moss breakdown, fertilizer, nitrogen fixing bacteria/algae, dissolved solids in the water and low humidity.
