Planting Plant hydrangeas in late spring or early fall to allow roots to establish before frost
Dig a hole twice as wide as the root ball and plant at the same depth as the nursery pot. Amend soil with compost to add nutrients and improve moisture retention
Light Requirements Hydrangeas prefer partial shade with morning sun and afternoon shade. They can tolerate full sun but may need extra water on hot days.
Soil Fertile, humus-rich, moist soil is ideal. Adjust soil pH to control bloom color - acidic soil (pH 6.0 or lower) produces blue flowers, neutral to alkaline soil (pH 7.0+) produces pink.
Watering Water hydrangeas 1-2 times per week during the growing season, saturating the soil. Stick your finger 4 inches into the ground and water if it feels dry
Reduce watering after heavy rain but increase during hot, dry spells. Curling leaves in hot weather is normal and doesn't necessarily mean the plant needs water
Fertilizing Fertilize hydrangeas once in early spring. Use a slow-release balanced fertilizer or one formulated for acid-loving plants.
