PLANTING and AFTERCARE GUIDE
Best Planting Time
Spring: Plant Penstemon ‘Alice Hindley’ in spring when the soil begins to warm. This allows time for the roots to establish before the flowering season, ensuring strong, healthy growth.
Autumn: Early autumn is also suitable for planting. This gives your Penstemon time to settle before entering winter dormancy and promotes robust spring growth.
Site Selection
Sunlight: Penstemon ‘Alice Hindley’ thrives in full sun but will also perform well in light, dappled shade. A minimum of 4–6 hours of direct sunlight daily will help encourage a strong floral display.
Soil: Choose a site with fertile, moist but free-draining soil. Avoid heavy, clay-rich areas prone to waterlogging, as Penstemon ‘Alice Hindley’ dislikes sitting in cold, wet ground. Improve drainage with compost or horticultural grit if needed.
Planting Instructions
Prepare the Ground: Dig a hole twice the width of the rootball and the same depth. This loosens the soil and allows for easy root establishment.
Soil Improvement: Enrich the planting area with compost or well-rotted organic matter to support healthy root development and sustained flowering.
Planting: Place the plant into the hole so the crown is level with the soil surface. Backfill, firm down gently, and water in thoroughly.
Spacing: Leave 45 cm between plants to allow for airflow and prevent fungal issues.
Watering Requirements
Establishment Phase: Keep the soil consistently moist during the first growing season after planting Penstemon ‘Alice Hindley’.
Ongoing Care: Once established, water during prolonged dry periods but allow the soil to partially dry between waterings. Avoid overwatering to reduce the risk of root rot.
Feeding
Spring Feed: In early spring, apply a balanced granular fertiliser to promote fresh growth and flower production.
Mid-Season Boost: A liquid feed every few weeks during the summer flowering season can help extend the bloom time and keep Penstemon ‘Alice Hindley’ vigorous.
Pruning and Deadheading
Deadheading: Regularly remove spent flowers to prolong the blooming season and keep the plant tidy.
Autumn Pruning: Cut your Penstemon back by about half after flowering finishes in autumn. Leave some stems over winter to protect the crown from frost. Final pruning to ground level can be done in spring.
Mulching
Spring: Apply a mulch of compost or bark around Penstemon ‘Alice Hindley’ in spring to retain soil moisture and suppress weeds.
Winter: In colder regions, mulch again in late autumn to insulate roots against frost.
Supporting the Plant
Staking: Penstemon ‘Alice Hindley’ typically holds its shape well, but in exposed spots or during wet weather, taller stems may benefit from discreet support to prevent flopping.
Final Tips
Penstemon ‘Alice Hindley’ is a low-maintenance, long-flowering perennial that rewards with soft colour and graceful form throughout summer. For best results, plant your Penstemon in a sunny position with fertile, well-drained soil, and ensure regular deadheading and feeding. Incorporating ‘Alice Hindley’ into your garden design not only adds elegance but also attracts bees and other pollinators, enhancing garden biodiversity.
