With proper care, hydrangeas can be a stunning addition to any garden.

Choosing The Right Location

When planting hydrangeas outdoors, choosing the right location is vital. The location impacts the plant’s growth and blooming. Below, we will explore the ideal sunlight conditions and soil requirements for hydrangeas.

Ideal Sunlight Conditions

Hydrangeas thrive in areas with morning sun and afternoon shade. Morning sunlight helps the plant grow strong. Afternoon shade protects it from heat. Too much direct sunlight can cause the leaves to wilt. Place the plant in a spot where it receives filtered light during the hottest part of the day.

Soil Requirements

Hydrangeas prefer soil that is well-drained and rich in organic matter. The soil should be moist but not waterlogged. A pH level between 5.5 and 6.5 is ideal for most hydrangea varieties. Use a soil test kit to check the pH level. If the soil is too alkaline, you can add elemental sulfur to lower the pH.

Here is a simple table to summarize the soil requirements:
