Success with lavender indoors starts with bright light. Place lavender plants in a sunny, south-facing window where they can receive 6-8 hours of sunlight daily. If needed, use a grow light to supplement light conditions.
Lavender can take a lot of heat, and it is best to keep it and most indoor plants away from air vents. Ideal indoor growth temperatures for lavender shouldn’t dip below 50 degrees at night.
