Why are my floating sweet-grass tips turning brown?

Brown tips on floating sweet-grass are a classic sign that the plant is not getting enough water or humidity. Since this is an aquatic plant, it needs to be wet constantly.

Check these first

  1. Check the water level in your container.
  2. Feel the soil to ensure it is saturated.
  3. Check if the plant is near a heater or air vent.

Likely causes

  1. Inconsistent water levels

    Most likely

    How to tell: The tips of the leaves turn crispy and brown while the rest of the plant looks dull. This happens when the water level drops below the soil line.

    What to do: Top off your container daily to ensure the soil remains submerged. Never let the soil dry out, even for a few hours.

  2. Low humidity

    Possible

    How to tell: The leaf tips brown even though the soil is wet. This occurs in very dry indoor environments or during extreme heat waves.

    What to do: Mist the foliage daily with a spray bottle. You can also place the plant in a larger tray of water to increase the local humidity.
