Planting Conditions

To cultivate thriving Aquilegia 'Barlow Black,' choose a location with well-drained soil and partial shade, especially in warmer climates. Plant in early Spring or Autumn, ensuring they are spaced about 12 inches apart. Ensure the soil is rich in organic matter and evenly moist, but avoid waterlogging. Mulch around the base of the plant to retain moisture and suppress weeds. With these conditions, 'Barlow Black' will flourish, offering its distinctive dark blooms and delicate foliage for the ideal cottage garden design.

Watering & Feeding

For Aquilegia 'Barlow Black,' maintain consistent soil moisture by watering regularly, especially during dry spells. However, avoid overwatering, as this can lead to root rot. Apply a balanced liquid fertiliser every four to six weeks during the growing season to promote healthy growth and abundant flowering. Monitor soil moisture levels and adjust watering frequency as needed, ensuring the soil remains evenly moist but not waterlogged. With proper watering and feeding, 'Barlow Black' will thrive and reward you with its striking dark blooms season after season.

General Care

Aquilegia 'Barlow Black' requires minimal care but benefits from occasional attention. Deadhead spent blooms to encourage continuous flowering if you wish to prevent self-seeding. Remove any damaged or yellowing foliage to maintain the plant's overall health and appearance. Pruning is generally unnecessary unless you want to control the plant's size or shape. However, if the plant becomes overcrowded, thin out excess growth to improve air circulation and reduce the risk of disease. With these simple care practices, 'Barlow Black' will flourish.
