PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The optimal time to plant Digitalis hybrida ‘Polkadot Polly’ is in spring when the soil begins to warm. This allows roots to establish firmly before the flowering season, resulting in a robust and healthy plant.
Autumn: Alternatively, plant in early autumn. This enables the plant to settle in before winter dormancy, encouraging stronger growth and blooms the following season.
Site Selection
Sunlight: Digitalis hybrida ‘Polkadot Polly’ thrives in full sun. Ensure the plant receives at least 6 hours of direct sunlight per day for vibrant flower production.
Soil: Choose well-drained soil, as Digitalis hybrida ‘Polkadot Polly’ does not tolerate waterlogged conditions. Enhance drainage and fertility by incorporating organic matter such as compost.
Planting Instructions
Prepare the Hole: Dig a hole twice the width and the same depth as the root ball to provide ample space for root expansion.
Soil Preparation: Mix in compost or organic matter to improve fertility and drainage, supporting vigorous growth for your Digitalis.
Planting: Position the plant in the hole with the top of the root ball level with the surrounding soil. Backfill gently and firm the soil to remove air pockets.
Watering After Planting: Water thoroughly to help settle the soil and encourage root establishment, ensuring the area drains well.
Watering Requirements
Growing Season: Once established, Digitalis tolerates moderate dry spells. Water during prolonged dry periods, allowing soil to slightly dry out between watering.
Dormant Season: Reduce watering in dormant periods. Only provide water if soil becomes excessively dry.
Feeding
Spring: Apply a balanced fertiliser in early spring to give Digitalis hybrida ‘Polkadot Polly’ a strong start to the growing season.
Mid-Summer: A light feeding during mid-summer promotes continuous flowering and maintains plant vigour throughout the bloom period.
Pruning
Deadheading: Regularly remove spent flowers from Digitalis hybrida ‘Polkadot Polly’ to prolong blooming, encourage new flowers, and maintain a tidy appearance.
Autumn Pruning: After the final flowers fade, cut back the plant to ground level to prepare for dormancy and promote healthier growth next season.
Mulching
Spring: Apply a layer of organic mulch around the base to retain moisture, suppress weeds, and regulate soil temperature.
Winter: Additional mulch during winter protects the roots from cold and prevents frost heaving.
Supporting the Plant
Staking: Digitalis hybrida ‘Polkadot Polly’ typically has sturdy stems, but in exposed or windy sites, staking may help prevent damage.
Final Tips
Digitalis hybrida ‘Polkadot Polly’ is a spectacular, low-maintenance perennial. Plant in full sun with well-drained soil and follow this care routine to enjoy bold red blooms from May to July. Its striking colour and pollinator-friendly flowers make it a standout addition to garden beds, borders, and cottage gardens.
