Growing True Lavender Indoors: Light, Pruning, and Longevity

Lavender needs full east sun and bottom heat indoors. North window + no artificial light = failure.

• Artificial light: 2-tube fixture (1 warm, 1 cool).
• Well-drained soil + lime annually.
• Prune each branch by 1/3 every 3 weeks in summer/fall.
• Varieties 'Provence', 'Grosso' have best scent.
• Dutch lavender is long-lived; seed longevity unknown.

Without proper light, indoor lavender won't thrive.
