Why are my American germander's leaf tips turning brown?

It is less common for this plant to have brown tips, but it usually happens due to low humidity or mineral buildup in the soil. Check your water quality or the air moisture levels first.

    How to tell: The tips turn brown and crispy while the rest of the leaf remains green.

  2. Salt Buildup

    Possible

    How to tell: A white crust appears on the soil surface or the rim of the pot.

    What to do: Flush the soil with distilled or filtered water to wash away excess minerals. Avoid using water with high chlorine or fluoride content.

Stopping it coming back

Use filtered water and keep the plant away from direct heat sources like vents or radiators.
