Propagation of Spirea

Are you looking to expand your spirea collection or share these lovely shrubs with others? Then, you’ve come to the right place! This comprehensive guide will walk you through various propagation spirea methods to help you achieve successful shrub cultivation.

Cutting Propagation:

  • Step 1: Select a healthy, non-flowering stem from the parent plant. Cut a 6-inch section just below a leaf node.
  • Step 2: Remove leaves from the bottom 1-2 inches of the stem. Dip the exposed end in rooting hormone.
  • Step 3: Plant the stem in a container filled with moist potting soil. Cover the container with a plastic bag to create a humid environment.
  • Step 4: Place the container in a shady location and keep the soil moist.
  • Step 5: Roots will develop within a few weeks to months. Once well-rooted, transplant your new spirea plant outdoors in the spring.

Seed Propagation:

  • Step 1: Collect seeds from the parent plant once they have matured and are dry.
  • Step 2: Stratify the seeds by placing them in the refrigerator for 1-2 months. This will help break their dormancy.
  • Step 3: Sow the stratified seeds in a tray filled with moist seed starting mix. Cover the seeds with a thin layer of soil.
  • Step 4: Keep the seeds moist and warm. Germination will occur within 2-3 weeks.
  • Step 5: Transplant the seedlings into individual pots once they have developed a few true leaves.

Vegetative Propagation:

  • Step 1: Dig around the base of the parent plant to expose the suckers, which are small shoots growing from the roots.
  • Step 2: Carefully separate the suckers from the parent plant and remove any attached roots.
  • Step 3: Plant the suckers in individual pots filled with moist potting soil.
  • Step 4: Keep the pots in a warm, shaded location and water them regularly.
  • Step 5: The suckers will develop roots within a few weeks. Once well-rooted, transplant them outdoors in the spring.
