Hydrangea Planting Guide: Timing, Location, Soil, and Sun

Everything You Need to Know to Plant Hydrangeas Successfully

A gardener asks when and where to plant hydrangeas, soil requirements, and sun exposure.

Planting Time

Now is fine (spring through early fall). Avoid summer heat waves and frozen ground.

Site Selection

• Space: They get "quite tall and wide"—check mature size of your cultivar
• Sun: Morning sun / afternoon shade ideal; full sun in cooler zones with ample moisture
• Wind: Protect from drying winds

Soil Requirements

• Moist but well-drained – Never soggy
• Moderately fertile
• Humus-rich – Amend with compost
• pH affects flower color (macrophylla types): Acidic = blue; alkaline = pink

Quick Checklist

1. Dig hole 2× root ball width, same depth
2. Backfill with native soil + compost
3. Water deeply
4. Mulch 2–3" (keep off stems)
5. Water regularly first season
