Likely causes
Inconsistent watering
Most likelyHow to tell: The leaf edges become crispy and brown while the rest of the leaf looks dull. This happens when the plant goes through cycles of being bone dry and then soaked.
What to do: Water deeply every 2 to 4 days when the top inch of soil feels dry. Use a consistent schedule to keep the soil evenly moist.
Low humidity
PossibleHow to tell: It is less common for this plant, but usually caused by dry indoor air or hot winds. The tips turn brown and brittle even when the soil is moist.
What to do: Mist the leaves occasionally or place a pebble tray with water near the plant. Avoid placing the hydrangea directly in front of air conditioning vents.

When to worry
If the browning covers more than half the leaf, the plant is struggling to hydrate itself. Minor browning on the very edges is common during hot summer months.
Stopping it coming back
Keep the soil consistently moist and protect the plant from harsh, drying winds.
