Soil Type

Water: Originating from the Canary Islands, fernleaf lavender thrives in dry, sunny conditions. It is drought-tolerant, preferring well-drained soil with minimal watering, about once a week. As an evergreen, fernleaf lavender requires consistent light and moderate temperatures to maintain foliage and manage water use effectively.

Fertilize: To enhance fernleaf lavender's growth and floral yield, apply half-strength high phosphorus fertilizers every 4-6 weeks during spring and summer. Reduce frequency in fall and winter to accommodate dormancy. Avoid over-fertilization to prevent excess foliage. Apply during watering for optimal distribution.

Pruning: Fernleaf lavender features fern-like foliage and an aromatic scent. Strategically prune in late winter to early spring and lightly after flowering to promote new growth and maintain shape. Regular pruning boosts air circulation, reduces disease risk, and encourages denser foliage. Use clean, sharp tools for effective care.

Propagation: Fernleaf lavender can be easily propagated by cuttings. Select a healthy non-flowering stem, cut below a leaf node, and remove lower leaves. Plant in sandy, well-draining soil, burying two nodes. Regular misting aids moisture. Optional rooting hormone can enhance root formation, though fernleaf lavender naturally roots well.

Repotting: Repot fernleaf lavender every 2-3 years in spring using a larger container with good drainage. After repotting, position fernleaf lavender in bright, indirect light and water moderately to support root establishment, considering its Mediterranean origins favoring a drier environment.
