Cycas cairnsiana

Cycas cairnsiana is a slow-growing cycad primarily found in Australia's tropical regions, featuring a stout trunk topped with a crown of stiff, glossy, dark green fronds. This prehistoric plant thrives in well-drained soils, with its deep roots and tough leaves adapting to survive dry spells. Cones emerge in the center of the leaf crown, with separate male and female plants producing pollen and seeds, respectively. Its striking foliage offers a glimpse into ancient landscapes, with cycas cairnsiana often a centerpiece in garden design due to its unique, palm-like appearance.

Water: Cycas cairnsiana requires ample water and good drainage, with watering twice a week. Outdoor potted plants need more frequent watering. Create a 3-inch mound 12 inches from the trunk to trap water. Ensure the top 10 inches of soil is moist to prevent root rot.

Fertilize: Cycas cairnsiana should be fertilized three times annually during its growing season using a slow-release fertilizer with an N-P-K ratio of 12-4-12. Incorporating micronutrients like manganese is beneficial. Mulching can enhance moisture retention, suppress weeds, and gradually provide more nutrients.

Pruning: Cycas cairnsiana should only be pruned by removing completely dead, damaged, or diseased leaves. Use sharp, clean shears to cut the oldest leaves near the trunk and disinfect tools to prevent contamination. Avoid removing healthy fronds to maintain plant strength against pests and diseases.
