To care for a Hoya 'Insularis', provide it with bright, indirect light and a well-draining soil mix, watering thoroughly only when the soil is dry to the touch to prevent root rot. Maintain consistent temperatures above 60°F (15°C) and increase humidity with a humidifier or by grouping it with other plants. Fertilize monthly during spring and summer, and avoid pruning the flower stalks to encourage more blooms.
