The recommended spacing for planting lavender varies depending on the purpose and lavender variety, but generally falls within these ranges:
- For informal garden plantings, space lavender plants about 45cm to 90cm (18 to 36 inches) apart, depending on the mature size of the plants
- For garden beds or borders, a spacing of about 20 to 40 cm (8 to 16 inches) between plants is ideal, with 30 to 40 cm often suggested to allow enough room for growth without overcrowding
- When planting lavender as a hedge, closer spacing of 30 to 45 cm (12 to 18 inches) apart is recommended for a dense effect
- For larger lavender cultivars or when planting in groups, spacing about 90 cm (3 feet) apart is advised
- True lavender (Lavandula angustifolia) generally needs 2 to 3 feet (60 to 90 cm) between plants, while Lavandin (Lavandula x intermedia) requires 3 to 4 feet (90 to 120 cm) spacing due to its larger size
- English lavender plants typically grow 1 to 2 feet wide and are spaced 18 to 24 inches (45 to 60 cm) apart to allow room for growth and airflow
In summary, for typical garden planting, spacing lavender plants about 30 to 45 cm apart works well for most varieties, with wider spacing (up to 90 cm or more) for larger types or group plantings. For hedges, closer spacing around 30 to 45 cm is best to create a full, formal look. Proper spacing ensures good air circulation, healthy growth, and ease of harvesting
