Planting Tips

Plant C. blassii nutrient-rich substrate, leaving the crown exposed. Like all Cryptocorynes, it may experience "Crypt melt" after transplanting — a temporary die-back of leaves as the plant adjusts to new water conditions. This is normal; healthy roots will produce new growth within a few weeks.

Each plant is sold as a rooted specimen, shipped with roots intact for the best transition into your tank.
