Care essentials
Light
Grow catnip in full sun to part shade. In NE Florida's intense summer heat, afternoon shade extends the plant's life. Plant in fall or early spring for best results.
Water
Drought tolerant once established; water moderately during establishment. In NE Florida, plant in fall or spring — the intense summer heat and humidity cause this plant to behave as a short-lived perennial or cool-season annual.
Soil & Fertilizer
Grows in average, well-drained sandy or loamy soil; thrives even in poor soils. Light spring fertilizer application is sufficient — overfertilizing in NE Florida's humid conditions promotes disease and reduces hardiness.
