Pick a variety that fits your climate and garden style:
Bigleaf (Hydrangea macrophylla) – Mophead or lacecap blooms; color changes with soil pH.
Panicle (Hydrangea paniculata) – Cone-shaped blooms; hardy and sun-tolerant.
Smooth (Hydrangea arborescens) – Includes ‘Annabelle’; great for colder regions.
Oakleaf (Hydrangea quercifolia) – Distinctive foliage and vibrant fall color.
Best Location and Soil
Hydrangeas thrive when planted in the right spot:
Morning sun with afternoon shade, especially in warm climates.
Protection from strong winds.
Well-draining, nutrient-rich soil—avoid soggy or heavy clay.
Slightly acidic soil if aiming for blue blooms.
Planting Hydrangeas
Dig a hole twice as wide as the root ball and equal in depth.
Remove the plant from its container and loosen roots.
Place in the hole with the root ball level to the ground.
Backfill with amended soil and water thoroughly.
Add 2–3 inches of mulch to retain moisture.
Best planting seasons: spring or fall.
Watering and Feeding
Water deeply 1–2 times per week, more in dry weather.
Avoid shallow watering—it weakens roots.
Apply a slow-release fertilizer in early spring and midsummer.
Use aluminum sulfate for blue blooms or lime for pink.
Pruning for Better Blooms
Pruning needs depend on the variety:
Bigleaf & Oakleaf – Bloom on old wood; prune right after flowering.
Panicle & Smooth – Bloom on new wood; prune in late winter or early spring.
General tips: remove weak stems, shape lightly, and avoid over-pruning.
Changing Bloom Colors
Blue flowers – Acidify soil (pH 5.2–5.5) with aluminum sulfate.
Pink flowers – Raise pH above 6.0 with lime.
White flowers – Color stays the same regardless of soil.
Seasonal Care
Summer – Keep watered and mulched.
Fall – Stop fertilizing; let plants prepare for dormancy.
Winter – Mulch around the base; protect buds in very cold regions with burlap or frost cloth.
Final Thoughts
Hydrangeas are lush, versatile, and surprisingly easy to care for. With the right variety, good soil, and a little seasonal maintenance, you’ll enjoy dramatic blooms year after year.
Plant them with care, follow these tricks, and let your garden glow with hydrangea beauty season after season.
