how far apart to plant hydrangeas
Hydrangeas are usually planted about 3–10 feet apart, depending on the type and the look you want, with most garden varieties doing best around 4–6 feet apart.
Quick Scoop
- Most hydrangeas: plan on about 4–6 feet between plants so they have room to reach their mature width without crowding.
- Smaller or compact varieties can go 2–3 feet apart; big, tree‑form or large oakleaf types may need 8–10+ feet.
- For a dense hedge, you can plant closer (about 3–4 feet apart for many bigleaf/smooth types), but you’ll do more pruning and they’ll compete more for water and nutrients.
- As a rule of thumb: take the plant’s mature width and add about 1 foot ; that’s a good spacing distance (e.g., a 5‑foot‑wide plant ≈ 6 feet apart).
Typical spacing by type
These ranges are for average varieties in each group:
- Bigleaf (Endless Summer–type, Nikko Blue, etc.): about 5–10 feet apart , many common garden selections are happy around 4–6 feet.
- Smooth (Annabelle‑type): about 2–6 feet apart , with 3–4 feet often used for hedges.
- Panicle (Limelight, Little Lime, etc.): about 2–4 feet for compact types; up to 10–15 feet for large, tree‑form types as specimens.
- Oakleaf: about 3–10 feet apart , with larger kinds needing 8–10 feet between individual shrubs.
If you’re planting right along a house wall, keep hydrangeas at least 3–4 feet away from the foundation so there’s airflow and space to work behind them.
Mini “forum‑style” perspective
“I planted mine about 2 feet apart for that Cape Cod clustered look and had to move every other one later because they were fighting for space once they hit 3–4 feet wide.”
Gardeners who plant very close (around 2 feet) often like the lush look at first but end up thinning or moving plants once they mature. Giving them that extra foot or two from the start usually means fewer headaches and healthier shrubs over time.
