Choose the Right Type of Hydrangea
There are several hydrangea varieties, and choosing the right one for your climate and garden conditions is the first step to success. The most popular types include:
Hydrangea macrophylla (Bigleaf): Known for its large blue, pink, or purple blooms. These are often the ones whose flower color changes based on soil pH.
Hydrangea paniculata (Panicle): Hardy and sun-tolerant with cone-shaped white blooms that fade to pink or green.
Hydrangea arborescens (Smooth): Easy to grow and great for colder regions. Produces large white blooms, such as the popular ‘Annabelle’ variety.
Hydrangea quercifolia (Oakleaf): With unique oak-like leaves and white blooms that age to rose or tan, this variety offers four-season interest.
Choose the variety that fits your sun exposure, space, and climate for the best success.
Planting Location and Soil Conditions
Hydrangeas thrive in well-draining, rich, and slightly acidic to neutral soil. The ideal location receives morning sun and afternoon shade, although panicle varieties can tolerate full sun, especially in cooler regions.
When planting:
Dig a hole twice as wide and as deep as the root ball.
Mix in compost or organic matter to enrich the soil.
Place the plant so the crown is level with the soil surface.
Fill the hole and water deeply.
Space your hydrangeas based on their mature size—generally 3 to 10 feet apart depending on the type.
Watering and Mulching
Hydrangeas love moisture but dislike soggy roots. Water deeply and consistently, especially in the first year after planting. During hot or dry spells, water 2 to 3 times per week.
