PLANTING and AFTERCARE GUIDE
Best Time to Plant
Spring Planting: Plant Thalictrum ‘Nimbus Pink’ in spring as the soil begins to warm. This gives the plant time to establish a strong root system before the growing season.
Autumn Planting: Planting in early autumn is another excellent option, allowing your Thalictrum to settle in before dormancy and re-emerge healthy in spring.
Ideal Planting Site
Sunlight: Thalictrum ‘Nimbus Pink’ prefers a position in dappled shade. It thrives in areas with filtered sunlight, such as under trees or alongside taller plants.
Soil: Choose moist, well-drained soil for Thalictrum ‘Nimbus Pink.’ Adding organic matter like compost improves soil fertility and texture, ensuring the plant flourishes.
Planting Instructions
Prepare the Planting Hole: Dig a hole twice as wide and as deep as the root ball to allow the roots of Thalictrum ‘Nimbus Pink’ to spread comfortably.
Enhance the Soil: Mix organic matter such as compost or leaf mould into the soil to boost nutrients and improve drainage.
Position the Plant: Place the root ball into the hole, ensuring the top is level with the surrounding soil. Avoid planting too deep, as this can hinder growth.
Backfill and Water: Refill the hole, firming the soil gently around the roots to remove air pockets. Water thoroughly to settle the soil.
Watering Requirements
Growing Season: Thalictrum thrives in moist soil, so water consistently during the growing period, particularly in dry spells. Avoid letting the soil dry out completely.
Dormant Season: Reduce watering in autumn and winter, as the plant requires less moisture when dormant.
Feeding
Spring: Apply a balanced, slow-release fertiliser in early spring to encourage healthy growth and vibrant blooms.
Mid-Summer: A light liquid feed during the flowering period can boost blooming and overall plant vigour.
Pruning and Maintenance
Deadheading: Regularly remove spent flowers from Thalictrum ‘Nimbus Pink’ to prolong the blooming season and maintain a tidy appearance.
Autumn Pruning: After flowering, cut back stems to ground level in autumn. This helps the plant prepare for dormancy and promotes healthy growth the following spring.
Mulching
Spring Mulch: Add a 5-7cm layer of organic mulch, such as bark or compost, around the base of Thalictrum ‘Nimbus Pink’ in spring. This helps retain moisture, suppress weeds, and regulate soil temperature.
Winter Mulch: Mulching in late autumn protects the plant’s roots from cold weather and prevents frost heaving.
Supporting Growth
Natural Habit: Thalictrum ‘Nimbus Pink’ grows to a height of 70cm with a spread of 40cm. Its compact size rarely requires staking, but support may be helpful in windy areas to protect the delicate stems.
