Salvia grow best in light shade with no more than 3 or 4 hours of direct morning or afternoon sunlight and well-drained soil. Avoid direct sunlight during midday. They won’t tolerate a lot of strong direct sunlight.
The stems of Salvia are not very strong. When the plants get taller than about one meter they tend to fall over if not given support. They prefer a fairly humid atmosphere and respond well to regular feeding.
