Solomon’s Seal (Polygonatum spp.) is a beautiful perennial plant that is native to North America, Europe, and Asia. It is known for its arching stems, paired oval-shaped leaves, and delicate bell-shaped flowers that hang beneath the foliage. If you have a Solomon’s Seal plant in your garden and would like to propagate it, there are several methods you can use to ensure success. In this article, we will explore the different ways to propagate Solomon’s Seal plant and provide step-by-step instructions for each method.

Propagation by Division

Division is the most common method used to propagate Solomon’s Seal plant. This technique involves separating the root clumps of an established plant into smaller sections, each containing a portion of the root system and attached shoots. Here’s how you can propagate Solomon’s Seal plant by division:

  1. Start by selecting a healthy and mature Solomon’s Seal plant with multiple stems and a well-developed root system.
  2. Choose a time when the plant is dormant, either in early spring before new growth emerges or in late fall after the foliage has died back.
  3. Carefully dig around the base of the plant to expose the root system without damaging it.
  4. Gently separate the root clump into smaller sections using a sharp knife or garden fork. Each section should have at least one stem and several healthy roots attached.
  5. Plant each divided section immediately in well-draining soil enriched with organic matter.
  6. Water thoroughly after planting and keep the soil consistently moist until new growth appears.

Propagation by division is best done every three to five years to rejuvenate older plants and promote healthy growth.

Propagation by Rhizome Cuttings

Another way to propagate Solomon’s Seal plant is through rhizome cuttings. Rhizomes are underground stems that produce roots and shoots. By taking cuttings from the rhizomes, you can create new plants that are genetically identical to the parent plant. Here’s how you can propagate Solomon’s Seal plant by rhizome cuttings:

  1. Select a healthy and mature Solomon’s Seal plant with well-developed rhizomes.
  2. Choose a time when the plant is dormant, either in early spring or late fall.
  3. Carefully dig around the base of the plant to expose the rhizomes without damaging them.
  4. Select a healthy and plump rhizome and use a clean, sharp knife to make a horizontal cut just below a bud or node.
  5. Cut the rhizome into sections, making sure each section has at least one bud or node.
  6. Plant each cutting horizontally in a well-draining potting mix, burying it just below the surface.
  7. Water thoroughly after planting and place the pot in a warm and bright location, avoiding direct sunlight.
  8. Keep the soil consistently moist but not waterlogged, and mist the cuttings regularly to maintain high humidity.
  9. After a few weeks, new shoots should emerge from the buds or nodes, indicating successful root formation.

Once the cuttings have rooted and established themselves, they can be transplanted into individual pots or directly into the garden.

Propagation by Seed

While division and rhizome cuttings are more common methods of propagating Solomon’s Seal plant, it is also possible to grow new plants from seeds. However, keep in mind that growing Solomon’s Seal from seed can be more challenging and time-consuming. Here’s how you can propagate Solomon’s Seal plant by seed:

  1. Collect ripe berries from an existing Solomon’s Seal plant when they turn dark blue or black.
  2. Remove the pulp from the berries by gently crushing them in water and rinsing away the pulp.
  3. Spread the seeds on a paper towel or a tray lined with a moistened, sterile seed-starting mix.
  4. Cover the seeds lightly with a thin layer of the seed-starting mix or vermiculite.
  5. Place the tray in a cool and dark location, such as a refrigerator or unheated garage, for a period of stratification. This mimics the natural winter dormancy period and helps break seed dormancy.
  6. After 8-12 weeks of stratification, move the tray to a warm and bright location, maintaining consistent moisture levels.
  7. Germination may take several weeks to several months, so be patient and continue to provide proper care.
  8. Once the seedlings have developed several sets of leaves and are large enough to handle, they can be transplanted into individual pots or directly into the garden.

Propagation by seed requires patience and attention to detail, but it can be a rewarding way to grow new Solomon’s Seal plants.

In conclusion, Solomon’s Seal plant can be propagated through division, rhizome cuttings, or seeds. Each method has its own advantages and challenges, so choose the one that suits your preferences and resources. Whether you decide to divide an established plant, take rhizome cuttings, or grow from seeds, following these step-by-step instructions will help ensure successful propagation of your Solomon’s Seal plants. With proper care and patience, you can enjoy an abundance of these lovely perennials in your garden for years to come.
