How to Grow Hydrangeas Successfully
Growing hydrangeas starts with choosing the right spot and variety. These versatile flowering shrubs come in many forms, including bigleaf, oakleaf, panicle, and the popular Endless Summer hydrangea. They thrive in rich, well-drained soil and need consistent moisture—especially in warmer climates. The best time to plant hydrangeas is in early spring or fall, giving the roots time to establish before extreme temperatures set in.
To succeed with hydrangea cultivation, consider the specific type you’re planting. Big leaf hydrangea care, for instance, often includes attention to soil pH for color control, while care for oak leaf hydrangea may focus more on pruning and fall protection.

Choose a location with morning sun and afternoon shade. Avoid full shade or intense afternoon sun, which can stress the plant.
How do I care for hydrangeas in pots?
When growing a hydrangea in a pot, choose a large container with good drainage. Use rich potting soil, keep it well-watered, and feed regularly. Consider moving the pot to a sheltered spot in winter for protection.
