Care Guide

Campanula Addenda® Mix is simple to care for, rewarding gardeners with a long season of blooms for minimal effort.

Planting

• Plant in full sun or partial shade; too much shade may reduce flowering.

• Use fertile, well-drained soil enriched with compost.

• In containers, use a quality multipurpose compost with added slow-release fertiliser.

• Space plants about 20–25cm apart to allow for spreading growth.

Watering & Feeding

• Keep soil consistently moist, especially during dry weather.

• Water container plants regularly, as they dry out more quickly.

• Feed every 2–3 weeks with a balanced liquid fertiliser to prolong flowering.

Pruning & Maintenance

• Deadhead faded blooms to encourage new flowers.

• Lightly trim back after the first flush of flowers to promote a second wave.

• Cut back hard in late autumn or early spring to tidy up the plant.

Protection

• Fully hardy and frost-tolerant, though container plants may benefit from shelter in very harsh winters.

• Generally pest- and disease-free, though keep an eye out for slugs on young plants.
