Care

  • Water: Ninebark is drought-tolerant once it’s established, which means it doesn’t need a lot of water. Just water it regularly during the first growing season, then it can handle drier conditions on its own or occasional overwatering.
  • Light: Ninebark loves sunlight! It thrives in full sun but can tolerate some partial shade. More sunlight helps keep the plant’s colors bright and vivid.
  • Soil: This shrub isn’t picky when it comes to soil. It can grow in neutral to acidic sandy, clay, or loamy soil as long as it’s mostly well-draining. Adding compost can help the soil stay healthy and nutrient-rich.
  • Temperature and Humidity: Ninebark is tough! It can handle cold winters and moderately hot summers. It grows best in zones 3-7, so it’s perfect for a wide range of climates.

Planting & Growing

You can grow ninebark from hardwood cuttings or by air layering, but some varieties are patented and can’t be propagated.

For cuttings, take hardwood pieces in late fall, dip them in rooting hormone, and store them in a plastic bag with moist moss until spring. Then, plant them in pots, water regularly, and wait for them to root by the next growing season.

For air layering, bend a branch into the soil, secure it, and check for roots in early fall. Once rooted, cut the branch from the main plant and replant it.

Pruning

Pruning your ninebark shrub is essential for keeping it healthy and looking its best. The best time to prune is between late winter and early summer, right after the shrub starts to bloom. Start by removing dead or damaged branches and thinning out crowded areas to help the plant grow better.

Light pruning in early summer can keep your shrub tidy, but avoid heavy cuts after mid-summer as the plant begins to slow down. For more info, check out our full guide below on Pruing Ninebark the Right Way!
