DETAILS

Care Instructions
Cycas thouarsii requires bright, direct sunlight for optimal growth. It thrives in warm temperatures and moderate humidity. Water the plant when the soil is almost completely dry, but avoid waterlogging. This plant can be grown outdoors in tropical climates but is not suitable for indoor growth.
Soil
The Madagascar Cycad prefers well-draining loamy soil. Ensure the soil mix allows for good drainage to prevent root rot. A mix of sand and organic matter can be beneficial.
Fertilizer
Use a balanced fertilizer with an N-P-K ratio of 10-10-10. Fertilize the plant during the growing season, typically every 4-6 weeks. Avoid over-fertilizing as it can harm the plant.
Repotting
Repot Cycas thouarsii every 2-3 years or when it outgrows its current pot. Choose a slightly larger pot with good drainage. Handle the roots carefully to avoid damage.
Propagation
Propagation is typically done through seeds or offsets. Collect seeds from mature cones and plant them in a well-draining soil mix. Offsets can be separated from the parent plant and planted individually.
Pruning
Prune dead or yellowing leaves to maintain the plant's appearance and health. Pruning can be done during the growing season. Use clean, sharp tools to make clean cuts.
Toxicity
Cycas thouarsii is toxic to pets and humans if ingested. All parts of the plant contain toxins, but the seeds are particularly dangerous. Symptoms of poisoning include vomiting, diarrhea, and liver failure.
