Most hydrangeas prefer partial shade, especially in the afternoon. They thrive with 4-6 hours of sun, ideally in the cooler morning hours.
Avoid planting them in full sun, as it can cause the flowers to wilt and turn brown quickly. The further north your garden is located, the more sunlight your hydrangeas need.
An average rule of thumb is 6 hours of sunlight per day, but in the South, they can perform well with just 3 hours of sunlight
Hydrangeas like morning sun but do not do well in direct, hot afternoon sun. Partial shade in the later parts of the day is ideal
If planting in full sun, increase watering to prevent wilting and browning, as hydrangeas require consistent moisture. Water them regularly to keep the soil consistently moist, especially in hot weather
If your hydrangeas are in a spot that gets too much sun, transplant them to a shadier location. The best times to transplant are in fall when dormant or early spring before new growth
By providing your hydrangeas with the right balance of morning sun and afternoon shade, you can ensure they thrive and produce beautiful blooms.
