Likely causes
Inconsistent Watering
Most likelyHow to tell: The soil is bone dry and cracked around the plant. The leaves look wilted before the tips turn brown.
What to do: Water deeply every 3 to 7 days to keep the soil evenly moist. Use a layer of mulch around the base to help hold moisture in the ground.
Heat Stress
PossibleHow to tell: The brown tips appear during a period of extreme heat or direct, intense sun. The rest of the leaf may look healthy but slightly limp.
What to do: Provide some afternoon shade using a garden cloth if temperatures soar. Ensure the plant gets plenty of water to help it cope with the heat.
