✂️ Care
Plant in a fine, nutrient-rich substrate in the foreground. Ensure maximum lighting and medium-hard water. The plant will lose its emersed leaves after submersion — this is normal. Liquid fertilizers like Sera Florena and root tabs support healthy growth.
💡 Planter's tip
In the right conditions, Tenellus forms a dense carpet via runners. Combines well with other small foreground plants.
