How Far Apart to Plant Lavender: Complete Guide

How Far Apart to Plant Lavender: Complete Guide

How Far Apart Do You Plant Lavender?

Lavender should be planted 12 to 36 inches apart, depending on the variety. Compact types like Lavandula angustifolia 'Munstead' need only 12–18 inches between plants, while larger varieties such as Lavandula x intermedia 'Grosso' require 24–36 inches to ensure proper air circulation, sunlight exposure, and healthy growth.

Why Spacing Matters for Lavender Growth

Proper spacing is essential for lavender health, yield, and disease prevention. Crowded plants trap moisture, increasing the risk of fungal diseases like root rot and gray mold. Adequate spacing promotes airflow, reduces competition for nutrients, and supports bushier growth and more abundant flowering.

Common Issues from Incorrect Spacing

Spacing Guidelines by Lavender Type

Different lavender species and cultivars vary significantly in mature size, which directly affects optimal planting distance.

English Lavender (Lavandula angustifolia)

Ideal for cooler climates and garden beds, English lavender typically reaches 12–24 inches in height and spread. Space plants 12–18 inches apart for hedges or mass plantings.

French Lavender (Lavandula stoechas)

Less cold-hardy but with showy bracts, French lavender grows 18–36 inches wide. Allow 24–30 inches between plants to accommodate its broader canopy.

Hybrid Lavender (Lavandula x intermedia)

Also known as lavandin, this group includes high-oil-yield varieties like 'Grosso' and 'Provence'. These can reach 24–36 inches in width and should be spaced 24–36 inches apart, especially in commercial fields.

Lavender Variety Mature Width (inches) Recommended Spacing (inches) Hardiness Zone Primary Use
Lavandula angustifolia 'Munstead' 12–18 12–18 5–8 Garden ornamental, culinary
Lavandula angustifolia 'Hidcote' 18–24 18–24 5–8 Edging, fragrance
Lavandula x intermedia 'Grosso' 24–36 24–36 6–9 Essential oil, drying
Lavandula x intermedia 'Provence' 24–30 24–30 6–9 Cutting gardens, oil production
Lavandula stoechas 'Anouk' 18–24 24–30 7–9 Ornamental, containers

The data shows a strong correlation between mature plant width and recommended spacing, confirming that growers must account for full-grown dimensions. Commercial producers often use wider spacing (up to 36 inches) even for smaller types to facilitate mechanical harvesting and airflow management.

Planting Tips for Optimal Lavender Spacing

Row Spacing in Garden Beds

When planting in rows, leave 30–36 inches between rows to allow access for pruning and harvesting. This is especially important for larger hybrid varieties grown for oil or dried bouquets.

Spacing for Hedges and Borders

For low hedges using dwarf English lavender, space plants at the minimum end of their range (e.g., 12 inches apart). This creates a dense appearance within one growing season while still allowing sufficient airflow once established.

Container Growing Considerations

In pots, match container size to variety. A 12-inch pot suits most English types, while larger hybrids need 16–20 inch containers. Avoid planting multiple lavenders in one pot unless it's exceptionally large (24+ inches).

Common Questions About Lavender Spacing

Can you plant lavender too far apart?

While over-spacing doesn't harm individual plants, it delays the formation of continuous hedges or ground cover. In commercial settings, excessive spacing reduces yield per acre. However, wider spacing improves air circulation and is beneficial in humid climates.

What happens if you plant lavender too close together?

Overcrowding restricts airflow, increases humidity around foliage, and raises the risk of fungal diseases like botrytis. It also leads to leggy growth due to competition for light and may reduce flower yield and oil concentration.

How far apart should I plant lavender in a row?

Space lavender plants 18–36 inches apart in a row, depending on variety. Leave 30–36 inches between rows for easy access, especially when growing tall or wide cultivars like 'Grosso' or 'Provence'.

Does lavender spread over time?

Yes, lavender slowly expands outward each year through new shoots from the base. Most varieties double in size within 2–3 years. Proper initial spacing accounts for this expansion to prevent future crowding.

Can lavender be planted next to other herbs?

Yes, but choose companions carefully. Lavender pairs well with rosemary, sage, and thyme—plants that prefer similar dry, well-drained soil and full sun. Ensure at least 12–18 inches between lavender and neighboring plants to avoid root competition.
