Cultivation and Care of Penstemon ‘Apple Blossom’:
Light Requirements: Full sun (at least 6 hours of direct sunlight per day) is ideal. It tolerates light shade but may not flower as profusely.
Soil Requirements: Well-drained soil is crucial. Penstemon ‘Apple Blossom’ prefers rocky or sandy soils and does not thrive in overly rich or moist conditions.
Watering: Water well until established. Once established, it is drought tolerant but looks better with occasional irrigation, especially in hot, dry climates. Avoid over-watering, as this can lead to root rot.
Fertilization: This plant does not require heavy fertilization. A light application of organic fertilizer in the fall can boost growth and flowering potential.
Pruning: Deadhead spent flowers to encourage continuous blooming. Cut back plants in late autumn or early spring to promote vigorous growth. Pinching back after the first bloom can promote a quick re-bloom.
Mulching: Apply mulch to help regulate soil temperature and suppress weeds. Use materials like shredded bark, compost, or pine straw, but avoid direct contact with the stems to prevent rot.
