Likely causes
Underwatering
Most likelyHow to tell: The tips of the leaves become crispy and brown while the rest of the leaf feels dry. The plant may also look wilted during the hottest part of the day.
What to do: Water your hydrangea deeply every 2 to 4 days. Make sure the water reaches the entire root ball rather than just the surface.
Fertilizer Burn
PossibleHow to tell: It is less common for this plant, but usually caused by applying too much synthetic fertilizer at once. You will see sharp brown edges on the leaves that appear shortly after feeding.
What to do: Flush the soil with plenty of plain water to wash away excess salts. Avoid fertilizing again until the plant shows signs of new, healthy growth.
