From Weed to Wonder: Propagating the Edible Sonchus oleraceus

Often dismissed as a pesky weed, Sonchus oleraceus, also known as common sow thistle, holds a surprising secret: it’s a delicious and versatile edible plant! And even better, it’s incredibly easy to propagate.

This blog post will guide you through the simple methods of starting your own sow thistle patch, whether you’re aiming for a sustainable salad source or simply want to explore the world of edible weeds.

The Power of Seeds

Sonchus oleraceus spreads primarily through its seeds, which are prolific and easily dispersed by the wind. But fear not, this means you have a plentiful source of plantlets ready for harvesting!

1. Seed Collection:

• Locate mature Sonchus oleraceus plants, identified by their yellow dandelion-like flowers.
• Wait for the seed heads to turn fluffy and white, indicating ripeness.
• Carefully collect the seed heads and store them in a dry, paper bag to allow for air circulation.
• The seeds can be stored for several months in a cool, dark and dry place.

2. Direct Sowing:

• Sow seeds directly into your garden during spring or late summer.
• Choose a sunny spot with well-drained soil.
• Lightly scatter the seeds on the soil surface and gently press them in.
• Keep the soil moist but not waterlogged.
• Seedlings should emerge within a few weeks.

3. Starting Indoors:

• For earlier harvest, sow seeds indoors about 4-6 weeks before the last frost date.
• Use seed trays or small pots filled with seed-starting mix.
• Gently mist the soil surface with water.
• Cover the tray with a clear plastic dome or wrap to create a humid environment.
• Keep the tray in a warm, sunny location.
• Once seedlings have 2-3 true leaves, they are ready to be transplanted outdoors.

The Magic of Cuttings

Sonchus oleraceus can also be propagated through stem cuttings.

1. Selecting Cuttings:

• Choose healthy, non-flowering stems from the plant.
• Select stems that are about 4-6 inches long and have several leaves.
• Cut the stems just below a leaf node.

2. Planting Cuttings:

• Prepare a moist, well-drained soil mix.
• Plant the cuttings in pots or directly in the garden.
• Make sure the lower leaf node is buried in the soil.
• Keep the soil moist and the cuttings in a warm, sunny location.

3. Success in a Few Weeks:

• Cuttings should root within a few weeks, forming new plants.
• When they are established, you can transfer them to their permanent location in the garden.
