PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The optimal time to plant Dipsacus fullonum is in spring when the soil begins to warm. This allows seedlings or transplants to establish strong roots before flowering.
Autumn: Early autumn planting is also suitable, giving the plant time to settle before winter dormancy.
Site Selection
Sunlight: Dipsacus fullonum thrives in full sun but will tolerate light shade. Choose a location that receives at least 6 hours of sunlight daily for vigorous growth.
Soil: Well-drained soil is essential for Dipsacus fullonum, which does not tolerate waterlogging. Incorporate organic matter like compost to improve fertility and drainage.
Planting Instructions
Prepare the Hole: Dig a hole twice the width of the root ball and the same depth. This provides ample room for root expansion.
Soil Preparation: Mix compost or organic matter into the planting soil to boost nutrients and drainage.
Planting: Place Dipsacus fullonum in the hole, ensuring the top of the root ball is level with surrounding soil. Backfill gently, firming the soil to eliminate air pockets.
Watering After Planting: Water thoroughly after planting to settle the soil and encourage root establishment. Ensure the area drains well to prevent root rot.
Watering Requirements
Growing Season: Once established, Dipsacus fullonum is moderately drought-tolerant. Water during dry periods, allowing soil to dry slightly between watering. Avoid excessive moisture, which can lead to root issues.
Dormant Season: Reduce watering significantly during dormancy, only supplementing if the soil becomes very dry.
Feeding
Spring: Apply a balanced fertiliser in early spring to promote healthy growth and prepare for flowering.
Mid-Summer: A light feed during mid-summer can support prolonged flowering and maintain plant vigour.
Pruning
Deadheading: Regularly remove spent flowers if you wish to prevent self-seeding. Leaving some seed heads can provide winter interest and food for birds.
Autumn Pruning: After flowering, cut Dipsacus fullonum stems back to ground level to prepare for winter and encourage strong regrowth.
Mulching
Spring: Apply mulch around the base to retain moisture, suppress weeds, and regulate soil temperature. Use organic mulch such as bark chips or compost.
Winter: Mulching in winter protects roots from frost and prevents soil heaving, ensuring the plant survives through colder months.
Supporting the Plant
Dipsacus fullonum produces tall, sturdy stems, but in exposed areas, staking may be necessary to prevent flopping.
Final Tips
Dipsacus fullonum is a striking, low-maintenance plant that adds vertical interest and attracts pollinators. By planting it in full sun with well-drained soil and following this care routine, your Dipsacus fullonum will thrive, offering architectural beauty, vibrant summer flowers, and wildlife value from mid-summer through winter.

Nice healthy looking plant. Didn’t expect the leaves to have spines. Got one embedded in my hand so beware!! I’d only put my hands down in the box to have a nosey.
