Growing in the kit
[Your data: how the kit is set up, how much water the reservoir holds, how often to refill it, where to place it for light, and what temperatures work.]
Houpu magnolia prefers fertile, moist, acidic soil in a sunny, wind-sheltered spot.
Year one and beyond
[Your data: milestones, such as first true leaves, height at 4, 8 and 12 weeks, and when a seedling is ready to move to a larger pot or the ground.]
In favorable sites it can add up to about 20 inches a year. Wild trees are listed as Endangered, in part because of historical bark stripping for traditional Chinese medicine.

Troubleshooting and FAQ
My seeds are not sprouting. Not every seed is viable. [Your data: how many seeds are in the vial and the germination rate we see.]
My seedling is collapsing or has gray mold. Seedlings are prone to damping-off, a fungal problem linked to excess moisture and poor airflow. [Your data: what to look for and what to do.]
Can I plant it outside? Houpu magnolia is hardy in USDA zones 6 to 9. [Your data: climate guidance and timing.]
