Ox Tongue prefers medium to bright but will cope with medium, indirect. Harsh midday sun can scorch sensitive leaves, while too little light leads to leggy, sparse growth.
Keep Ox Tongue between 15–28 °C and aim for around 35% humidity (20% minimum). Below 5 °C it risks cold damage — keep it away from draughty windows and radiators.
