Planting Hydrangeas: Step-by-step Guide for Beginners

Hydrangeas are beautiful flowering plants that can add a touch of elegance to any garden. If you’re a beginner and want to start growing hydrangeas, follow this step-by-step guide to ensure successful planting:

1. Choose the Right Location

Hydrangeas prefer partially shaded areas with morning sun and afternoon shade. Avoid planting them in direct sunlight, as it can cause the leaves to wilt and burn. Select a spot in your garden that has well-draining soil and is protected from strong winds.
