PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: Plant Brunnera macrophylla ‘Dawson’s White’ in early to mid-spring when the soil begins to warm. This timing allows roots to establish before the heat of summer, ensuring healthy foliage and a strong display of spring flowers.
• Autumn: Alternatively, autumn is also ideal for planting. The cooler temperatures help the plant settle before winter, promoting vigorous growth in the next season.

Site Selection

• Light: Choose a location with partial to full shade. Brunnera macrophylla ‘Dawson’s White’ performs best where it is sheltered from harsh sunlight, which can scorch its variegated foliage.
• Soil: Ensure the soil is rich, moist, and well-drained. Incorporating organic matter like compost improves moisture retention while still allowing excess water to drain—essential for preventing root rot.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width and the same depth as the plant’s root ball to give the roots room to spread.
2. Soil Enhancement: Mix compost or well-rotted manure into the planting hole to provide nutrients and improve soil structure.
3. Positioning: Place Brunnera macrophylla ‘Dawson’s White’ so that the crown is level with the soil surface. Backfill and gently firm the soil to remove air pockets.
4. Water Thoroughly: After planting, water deeply to help the plant settle in and encourage root establishment.

Watering Requirements

• Active Growth: Water Brunnera macrophylla ‘Dawson’s White’ regularly during dry periods, especially in spring and early summer. It prefers evenly moist soil but not waterlogged conditions.
• Dormancy: During late autumn and winter, reduce watering. Only water if the soil is particularly dry to prevent desiccation.

Feeding

• Apply a slow-release balanced fertiliser in early spring to support healthy foliage and flower production.
• A light mulch of organic compost or leaf mould can also provide a steady nutrient source and help retain moisture throughout the growing season.

Pruning and Maintenance

• After Flowering: Once the blue flowers have faded, cut back spent stems to tidy the plant and encourage fresh foliage growth.
• Late Season Tidy-Up: In autumn, remove any damaged or tired leaves to prepare the plant for winter.

Mulching

• Mulch in spring using organic material to retain soil moisture, suppress weeds, and enrich the soil.
• A winter mulch protects roots and helps insulate the plant through colder months, ensuring the long-term success of Brunnera macrophylla ‘Dawson’s White’.

Supporting the Plant

Brunnera macrophylla ‘Dawson’s White’ is naturally low-growing and forms a clump, so staking is not required. However, ensure it is not overshadowed by taller plants to maintain its visual impact.
