Water: Caladenia caerulea requires adequate moisture but can tolerate some drought. Water weekly in summer and every 10 days in fall/winter. Maintain humidity by misting, and use neutral pH water, neutralizing tap or rainwater before use to release dissolved CO2.

Fertilize: Caladenia caerulea requires minimal fertilization. Apply a nitrogen-rich fertilizer (N-P-K = 30-10-10) every 10 days post-sprouting in spring. Transition to a balanced fertilizer (N-P-K = 20-20-20) in early summer. Use phosphorus-rich fertilizer to enhance blooming in fall.

Pruning: Caladenia caerulea features delicate blue-tinged flowers and thrives with targeted pruning. Remove spent blooms and dead foliage in early spring for optimal growth. This approach supports recovery, maintains shape, and enhances flowering. Use clean, sharp tools to prevent diseases.

Propagation: Propagate caladenia caerulea through division or cuttings. For division, do it post-blooming, using clean tools and keeping roots intact. For cuttings, take 2-node pieces from healthy stems and keep the substrate moist, rooting in 2-3 months. Alternatively, propagate by layering stems in moist substrate.
