Choosing the Right Hydrangea Variety
Bigleaf hydrangea (Hydrangea macrophylla): Large mophead or lacecap flowers; partial shade; acidic to neutral soil.
Panicle hydrangea (Hydrangea paniculata): Cone-shaped clusters; full sun tolerant; cold-hardy.
Smooth hydrangea (Hydrangea arborescens): Hardy and adaptable; partial sun; moist soil.
Oakleaf hydrangea (Hydrangea quercifolia): Lobed leaves and seasonal color; well-drained soil; some shade.
Choose a spot with morning sun and afternoon shade.
Mix compost or aged manure to improve fertility and moisture retention.
Ensure good drainage to prevent root rot.
For potted hydrangeas, use high-quality, well-draining potting soil.
Watering Your Hydrangea
Keep soil consistently moist, but not soggy.
Use mulch to retain moisture and regulate soil temperature.
Avoid wetting leaves to reduce fungal diseases.
During hot spells, water deeply twice a week.
Fertilizing for Vibrant Blooms
Apply balanced, slow-release fertilizer in spring.
For acidic-soil varieties, use sulfur or aluminum sulfate to encourage blue blooms.
Avoid excessive nitrogen; it promotes leaf growth but reduces flowers.
Light and Temperature Needs
Bright, indirect light or dappled shade is ideal.
Protect from frost in colder zones with mulching or covering.Bigleaf & oakleaf: Prune after flowering (old wood).
Panicle & smooth: Prune in late winter/early spring (new wood).
Remove dead or damaged branches to improve airflow.
Avoid heavy pruning that removes too many buds.
