Welcoming the ancient and majestic Dioon spinulosum, popularly known as the Mexican Cycad. This slow-growing cycad, native to the rainforests of Mexico, boasts a sturdy trunk crowned with long, arching, blue-green fronds, exuding a prehistoric aura reminiscent of the age of dinosaurs. This plant could live up to 2,000 years!

How to Grow

The Mexican Cycad thrives in partial to full sunlight and requires well-draining soil, preferably with a sandy mix. While it's native to tropical climates, it's hardy and can withstand cooler temperatures, making it suitable for USDA zones 9-11.

Care Tips

Watering should be moderate. Allow the soil to dry out between watering sessions, as the plant is drought-tolerant and can be sensitive to over-watering. During its growing season, a balanced, slow-release fertilizer can be applied to nourish its growth.


With its sculptural form, the Dioon spinulosum serves as a striking focal point in gardens, particularly in xeriscapes or tropical-themed landscapes. Its architectural beauty also makes it a favored choice for containers or as an indoor specimen in spacious areas.

Planting Tips

When planting the Mexican Cycad, ensure a deep hole to accommodate its tap root. If potting, use a container with ample drainage holes. Mixing perlite or coarse sand into the soil can enhance drainage, catering to its natural habitat preferences.


Being a low-maintenance plant, the Mexican Cycad requires minimal upkeep. Periodically remove old or brown fronds to maintain its grand appearance. It's a slow grower, so patience is key to witnessing its full splendor.

Pests and Diseases

While generally resilient, watch out for scale insects or mealybugs. These can be managed with insecticidal soaps or horticultural oils. Ensure the plant isn't subjected to waterlogged conditions to prevent root rot.

Note: It's worth mentioning that all parts of the Dioon spinulosum are toxic when ingested. Ensure it's placed away from pets or children and handle with care when maintaining.
