DETAILS

Care Instructions
Guaiacum sanctum thrives in wet tropical climates with plenty of sunlight. It prefers consistently moist soil and high humidity. The tree should be placed in a location where it can receive direct bright light for most of the day. Moderate temperatures are ideal for its growth.
Soil
This tree prefers loamy soil that is well-draining yet retains moisture. The soil should be rich in organic matter to support its nutrient needs. Ensure the soil remains consistently moist but not waterlogged.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the tree during the growing season to support its development. Follow the manufacturer's instructions for frequency and application rates.
Repotting
Repotting is generally not necessary for Guaiacum sanctum as it is typically grown outdoors. However, if grown in a container, repot the tree every few years to refresh the soil and provide more space for root growth. Choose a larger pot with good drainage.
Propagation
Guaiacum sanctum can be propagated from seeds or cuttings. Seeds should be soaked in water for 24 hours before planting. Cuttings should be taken from healthy, mature wood and treated with rooting hormone before planting in a well-draining soil mix.
Pruning
Pruning is required to maintain the shape and health of the tree. Prune during the dormant season or after flowering. Remove any dead or diseased branches and shape the tree as desired.
Toxicity
Guaiacum sanctum is not known to be toxic to pets or humans. However, as with any plant, it is advisable to prevent pets and children from ingesting any part of the plant.
Additional
Guaiacum sanctum is a slow-growing tree, so patience is required when cultivating it. Its dense wood makes it highly resistant to pests and diseases, making it a relatively low-maintenance plant once established.
