Yes, you can absolutely grow lavender in urban planter boxes! Lavender thrives in containers when given the right conditions, making it perfect for balconies, patios, and small urban spaces. The key to success lies in choosing the appropriate variety, providing excellent drainage, and ensuring plenty of sunlight.
Start by selecting compact lavender varieties suited for containers, such as English lavender (Lavandula angustifolia) varieties like 'Hidcote' or 'Munstead'. French and Spanish lavenders also adapt well to container life. Your planter boxes should be at least 12-16 inches deep and wide to accommodate lavender's root system, with multiple drainage holes being crucial.
Use a well-draining potting mix specifically formulated for Mediterranean herbs, combining regular potting soil with perlite, coarse sand, or gravel. Lavender despises wet roots, so this drainage is non-negotiable. Position your planter boxes where they'll receive at least 6-8 hours of direct sunlight daily – south-facing locations typically work best.
Water lavender deeply but infrequently, allowing the soil to dry out between waterings. Overwatering is the most common cause of failure. During the growing season, feed with a balanced, slow-release fertilizer sparingly, as lavender prefers somewhat poor soil. Prune plants annually after flowering to maintain shape and encourage bushier growth.
With proper care, your urban lavender will reward you with beautiful purple spikes, delightful fragrance, and the added benefit of attracting pollinators to your city space.
