Likely causes
Underwatering
Most likelyHow to tell: The soil feels dry well below the top inch, and the leaves may feel brittle. The browning starts at the very tip and moves inward.
What to do: Water your plant deeply every 3 to 7 days until the soil is moist. Ensure the top inch of soil is dry before you add more water.
Heat Stress
PossibleHow to tell: This is less common for this plant and usually happens during intense summer heatwaves. The leaves look scorched and the tips turn brown despite regular watering.
What to do: Provide a bit of afternoon shade during the hottest part of the day. Mulch around the base of the plant to keep the roots cool.
