Care

Jacob’s Ladder Care

Plant in partial to full shade to prevent leaf scorch and promote healthy growth. While it can tolerate some morning sun, protection from intense afternoon sunlight is essential.

Prefers moist, well-drained soil enriched with organic matter. Ensure the soil remains consistently moist but not waterlogged. Incorporating compost or leaf mold can improve soil fertility and structure.

Water regularly, especially during dry spells, to maintain consistent soil moisture. Avoid allowing the soil to dry out completely, as this can lead to leaf browning and reduced vigor.

Apply a balanced, slow-release fertilizer in early spring to support robust growth and flowering. Our slow release fertilizer is a great option.

Deadhead spent flowers to encourage a potential second bloom and prevent self-seeding. After the blooming period, cut back the flower stems to maintain a tidy appearance and promote healthy foliage.

Divide clumps every 2 to 3 years in early spring or late summer to rejuvenate the plant and prevent overcrowding.

Space plants 12 to 18 inches apart to allow for adequate air circulation and room for growth.
