Hydrangeas Demystified

Tips for Success

  • Moist but well-drained soil (hydrangeas will not tolerate wet feet – ever!)
  • Some sun each day. Most people think of hydrangeas as shade plants, but they look and flower best with at least four hours of sun, ideally in the morning. Panicle hydrangeas are the most sun tolerant and can take full sun in northern climates.
  • Plenty of water, especially as they are getting established. Hydrangeas have shallow roots, so they dry out quickly. A two to three-inch layer of shredded bark mulch is a useful addition to any hydrangea planting.
