PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Thalictrum ‘Cotton Candy’ in spring when the soil begins to warm. This gives the plant time to establish roots before its main flowering period.
Autumn: Early autumn planting is also effective, allowing Thalictrum ‘Cotton Candy’ to settle before going dormant for winter and bursting into growth the following spring.
Site Selection
Sunlight: Choose a spot in dappled shade or partial shade. While Thalictrum ‘Cotton Candy’ appreciates some sun, it prefers protection from the hottest part of the day.
Soil: Well-drained, moisture-retentive soil is essential. Incorporate compost or leaf mould to enrich the soil and support the long-term health of Thalictrum ‘Cotton Candy’.
Planting Instructions
Dig the Hole: Create a hole twice the width of the root ball and the same depth.
Enrich the Soil: Mix in compost or well-rotted organic matter to boost drainage and nutrients.
Position the Plant: Place the plant in the hole so the crown is level with the soil surface.
Backfill and Water: Refill the hole, gently firm the soil, and water thoroughly to settle the roots.
Watering Requirements
During Growth: Keep the soil consistently moist, especially during dry spells. Thalictrum ‘Cotton Candy’ does not tolerate drought well.
After Establishment: Once established, water when the top layer of soil begins to dry out. Avoid letting the soil become soggy.
Feeding
Spring Feeding: Apply a balanced slow-release fertiliser in early spring to promote lush foliage and strong flower stems.
Midseason Boost: Lightly feed again in midsummer if flowering is prolonged or the plant looks tired. This will help your Thalictrum maintain its vigour.
Pruning and Maintenance
Deadheading: Remove faded flower stems to tidy the plant and prevent self-seeding.
End of Season: Cut back the stems to just above ground level in autumn once flowering has finished. This keeps Thalictrum ‘Cotton Candy’ healthy and encourages robust growth next year.
Mulching
Spring Mulch: Apply a layer of organic mulch in spring to lock in moisture and suppress weeds around Thalictrum ‘Cotton Candy’.
Winter Protection: Although hardy, a layer of mulch in winter helps insulate roots and protect young plants in colder spots.
Staking and Support
Support if Needed: Although stems are slim, they are sturdy. In exposed locations or when grown in rich soil, you may need to support Thalictrum ‘Cotton Candy’ to prevent flopping during wind or heavy rain.
