PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: The optimal time to plant Digitalis is in spring when the soil begins to warm. This helps roots establish firmly before the blooming season, promoting vigorous growth and healthy flower production.
Autumn: You can also plant Digitalis lutea in early autumn. This allows the plant to settle in before dormancy, encouraging stronger growth and flowering the following season.
Site Selection
Sunlight: Digitalis thrives in full sun to partial shade. Choose a location with at least 6 hours of direct sunlight for the best flower production.
Soil: Well-drained soil is essential for Digitalis lutea. Avoid waterlogged conditions as they can lead to root rot. Incorporate organic matter such as compost to improve soil fertility and drainage.
Planting Instructions
Prepare the Hole: Dig a hole twice as wide and equal in depth to the root ball of your Digitalis. This gives roots room to spread.
Soil Preparation: Mix in compost or organic matter to enrich the soil, supporting strong growth and vibrant blooms.
Planting: Place your Digitalis in the hole, ensuring the top of the root ball is level with surrounding soil. Gently backfill and firm the soil to remove air pockets.
Watering After Planting: Water thoroughly to help settle the soil and encourage root establishment. Ensure the area drains well to avoid waterlogging.
Watering Requirements
Growing Season: Once established, Digitalis is moderately drought-tolerant. Water during dry periods, allowing soil to dry slightly between watering sessions. Avoid overwatering to prevent root problems.
Dormant Season: Reduce watering significantly when the plant is dormant, only watering if soil becomes very dry.
Feeding
Spring: Apply a balanced fertiliser to give Digitalis lutea a strong start to the growing season. This promotes healthy leaf growth and abundant flower spikes.
Mid-Summer: A light mid-season feeding can extend flowering and maintain the vigour of Digitalis lutea throughout the blooming period.
Pruning
Deadheading: Remove spent flowers regularly to prolong blooming and keep Digitalis lutea looking tidy. This encourages new flower production.
Autumn Pruning: After flowering ends, cut Digitalis lutea back to ground level. This prepares the plant for dormancy and promotes strong growth for the next season.
Mulching
Spring: Apply mulch around the base of Digitalis lutea to retain moisture, suppress weeds, and regulate soil temperature. Use organic materials like bark chips or compost.
Winter: Mulching in winter protects roots from cold temperatures and prevents frost damage, ensuring Digitalis lutea survives through to the next growing season.
Supporting the Plant
Staking: Digitalis lutea typically has sturdy stems, so staking is rarely necessary. In windy locations, consider staking to prevent damage.
Final Tips
Digitalis lutea is a low-maintenance perennial that brings a splash of colour and attracts pollinators. By planting it in full sun or partial shade with well-drained soil, and following this care routine, your Digitalis will reward you with elegant blooms from June to July, adding charm to borders and wildlife-friendly gardens.
