Hydrangea Care: Complete Guide to Growing Stunning Blooms

Hydrangea Varieties

Understanding which type of hydrangea you have is essential for proper care:

• Bigleaf (H. macrophylla): Classic mophead and lacecap types, color changes with soil pH
• Panicle (H. paniculata): Cone-shaped flower heads, very cold-hardy
• Smooth (H. arborescens): Including 'Annabelle', native and shade-tolerant
• Oakleaf (H. quercifolia): Beautiful fall foliage, prefers some shade

Growing Conditions

Most hydrangeas prefer morning sun with afternoon shade, especially in hot climates. They need consistent moisture but won't tolerate waterlogged soil. A 2-3 inch layer of mulch helps retain moisture and keep roots cool.

Watering Needs

Hydrangeas are thirsty plants, especially in summer:

• Water deeply 2-3 times per week during dry spells
• Water at the base to keep foliage dry
• Wilting in afternoon heat is normal—check soil before watering
• Container hydrangeas may need daily watering

Pruning by Type

Wrong pruning is the most common reason for no blooms:

• Bigleaf types: Only remove dead stems; they bloom on old wood
• Panicle and smooth types: Prune in late winter; they bloom on new wood
• Reblooming varieties: Light pruning anytime; they bloom on both old and new wood

Changing Flower Color

Only bigleaf hydrangeas can change color based on soil pH:

• Acidic soil (pH below 6) produces blue flowers
• Alkaline soil (pH above 7) produces pink flowers
• White hydrangeas remain white regardless of pH
