Salt or Fertilizer Buildup

Accumulation of mineral salts from tap water or excessive fertilizer can burn the sensitive leaf tips of the 'Nevada' cultivar. This osmotic stress pulls moisture out of the leaf tissue.

Very Common

Underwatering / Inconsistent Moisture

If the medium dries out completely between waterings, the plant cannot transport enough moisture to the furthest extremities of the leaf. This leads to necrosis at the tips.

Root Rot (Overwatering)

Excessive moisture leads to anaerobic conditions and fungal pathogens like Phytophthora. As roots die, they can no longer supply water to the leaves, causing them to turn brown as if they were thirsty.

Common
