Inconsistent Watering

Fluctuating between bone-dry soil and saturated soil stresses the plant's vascular system. This instability often manifests as browning at the leaf edges as the plant struggles to regulate water uptake.

Root Rot (Early Stage)

While root rot usually causes yellowing, the initial stage of oxygen deprivation in the roots can prevent water from reaching the leaf tips, leading to localized browning.

Common

1 Inspect the roots for any mushy or dark discoloration and trim away any soft, damaged sections using sterilized tools.

2 Repot the plant in a highly aerated, well-draining medium by mixing existing soil with perlite or orchid bark to increase oxygen to the root zone.
