The brown tips spreading across your dracaena’s leaves are a physiological alarm bell. Here’s exactly what’s happening and how to reverse the damage.
For months, a plant parent followed the popular advice to let tap water sit overnight before watering their spider plant—only to watch the brown tips persist. The truth? That ritual targets the wrong culprit entirely, and understanding what actually causes the damage changes everything.
