Lavender in New Jersey's Climate

Your climate supports lavender well with proper drainage. English and hybrid lavender (Phenomenal, Grosso) thrive in the neutral-to-alkaline soils common in limestone regions. The biggest mistake is overwatering — lavender is Mediterranean and prefers dry feet. Prune in spring after new growth appears, never into old wood.

Soil Considerations for New Jersey

Sandy soils in Pine Barrens. Clay in north. Acidic in south. Rich loam in central agricultural areas. The Garden State for good reason.

New Jersey Climate & Growing Season
