PLANTING and AFTERCARE GUIDE

Best Planting Time

• Spring: The ideal time to plant Digitalis purpurea ‘Dalmatian White’ is in spring when the soil begins to warm. This ensures the roots establish before flowering, promoting strong, healthy growth.
• Autumn: You can also plant Digitalis purpurea ‘Dalmatian White’ in early autumn. Planting at this time allows it to settle before dormancy, supporting vigorous flowering in the following season.

Site Selection

• Sunlight: Digitalis purpurea ‘Dalmatian White’ performs best in full sun to partial shade. Choose a location that receives at least 6 hours of sunlight per day to encourage robust growth and abundant flowers.
• Soil: Well-drained soil is essential for Digitalis purpurea ‘Dalmatian White’. Avoid waterlogged areas, as the plant is prone to root rot. Incorporate organic matter like compost to improve soil fertility and drainage.

Planting Instructions

1. Prepare the Hole: Dig a hole twice the width and the same depth as the root ball to give the roots plenty of space to grow.
2. Soil Preparation: Mix compost or organic matter into the soil to boost fertility and drainage. Healthy, nutrient-rich soil encourages vigorous growth and strong flowering.
3. Planting: Position your Digitalis in the hole with the root ball level with the surrounding soil. Backfill gently, firming soil to remove air pockets.
4. Watering After Planting: Water thoroughly after planting to settle the soil and help the roots establish. Ensure the area drains well to prevent waterlogging.

Watering Requirements

• Growing Season: Once established, Digitalis tolerates moderate dry spells. Water when the soil starts to dry but avoid overwatering.
• Dormant Season: Reduce watering significantly during dormancy. Only provide water if the soil becomes extremely dry.

Feeding

• Spring: Apply a balanced fertiliser in early spring to encourage strong growth and vibrant flower production.
• Mid-Summer: A light feed in mid-summer can prolong flowering and maintain the vigour of Digitalis purpurea ‘Dalmatian White’.

Pruning

• Deadheading: Remove spent flowers regularly to extend the blooming period, keep the plant tidy, and encourage new flowers.
• Autumn Pruning: Cut back to ground level after flowering ends. This prepares the plant for dormancy and supports healthier growth the following season.

Mulching

• Spring: Apply a layer of mulch around the base of your Digitalis to retain moisture, suppress weeds, and regulate soil temperature.
• Winter: Mulching in winter helps protect the roots from cold and prevents frost heaving, ensuring survival through to the next season.

Supporting the Plant

• Staking: Digitalis purpurea ‘Dalmatian White’ has sturdy stems and usually does not require staking. In windy locations, consider staking to prevent stem damage.
