How to Grow a Field of Lavender Successfully

Growing a field of lavender successfully requires selecting the right variety, preparing well-drained soil, ensuring full sun exposure, proper spacing, and consistent but minimal watering—lavender thrives in hot, dry climates with low fertility soils and needs annual pruning to maintain health and yield.

Choosing the Right Lavender Variety for Field Cultivation

Selecting the appropriate lavender species is critical for large-scale success. Not all lavender types are suited for field production due to differences in hardiness, oil content, bloom yield, and climate adaptation.

Common Lavender Varieties Grown in Fields

For commercial fields, Lavandula x intermedia 'Grosso' is the most widely planted due to its vigorous growth, tall flower spikes, and high oil production.

Site Selection and Soil Preparation

Lavender demands excellent drainage and full sunlight. Poor site selection leads to root rot and plant loss, especially in humid regions.

Key Site Requirements

Before planting, conduct a soil test. Amend with lime if pH is below 6.5. Incorporate coarse sand or perlite into native soil to improve drainage. Raised beds (6–12 inches high) are recommended in areas with poor drainage.

Planting Lavender in the Field

Timing and spacing are crucial for air circulation, weed control, and harvest efficiency.

Optimal Planting Guidelines

Drip irrigation should be installed at planting to deliver water directly to roots and minimize foliage wetting, reducing fungal risks.

Watering, Fertilizing, and Maintenance

Overwatering is the leading cause of lavender failure. Once established, lavender is drought-tolerant.

Irrigation Schedule (First Year)

Mature plants require no supplemental water in most climates. Avoid nitrogen-rich fertilizers; excess promotes weak growth and reduces oil concentration. A light application of compost or balanced organic fertilizer in spring is sufficient.

Pest and Disease Management

Lavender is naturally resistant to deer and rabbits but vulnerable to fungal diseases in humid conditions.

Common Issues in Lavender Fields

Prevention through cultural practices is more effective than chemical treatments. Rotate crops if replanting and avoid overhead irrigation.

Harvesting and Post-Harvest Processing

Harvest when 50–70% of flowers have opened for peak oil content and color retention.

Best Practices for Harvesting

Dried lavender can be stored in airtight containers away from light. Essential oil distillation requires specialized equipment and is most efficient at commercial scale.

Variety Yield (lbs/acre dry buds) Essential Oil % USDA Zone Harvest Time (weeks after bloom)
Lavandula angustifolia 'Munstead' 800 1.8% 5–8 6–7
Lavandula x intermedia 'Grosso' 1,500 2.2% 6–9 7–8
Lavandula x intermedia 'Provence' 1,200 2.0% 6–8 7
Lavandula angustifolia 'Hidcote' 700 1.7% 5–8 6–7

The data shows that Lavandin varieties like 'Grosso' offer significantly higher yields and essential oil content, making them ideal for commercial operations. English lavenders such as 'Munstead' and 'Hidcote' provide lower yields but are preferred for fine fragrance products due to their sweeter aroma profile.

Frequently Asked Questions About Growing a Field of Lavender

How long does it take for a lavender field to mature?

Lavender reaches full maturity in 2–3 years. Plants produce limited blooms in the first year, with peak yields starting in year three when properly pruned and maintained.

Can lavender grow in clay soil?

Lavender struggles in heavy clay due to poor drainage. If growing in clay, amend soil heavily with sand and organic matter or plant on raised beds to prevent root rot.

How much money can you make growing lavender per acre?

Revenue varies by product type. Dried buds sell for $10–$20/lb, yielding $8,000–$30,000/acre annually. Essential oil ($30–$50/oz) can generate over $50,000/acre at full production, though startup and distillation costs are high.

Do you need bees to pollinate lavender?

No, lavender is self-fertile and primarily grown for its flowers and oil, not seed. However, bees are strongly attracted to blooming lavender and enhance biodiversity and nearby crop pollination.

When should you prune lavender in the field?

Prune in early spring before new growth starts. Remove one-third of the plant’s height, avoiding cutting into old wood. Light shaping can also be done after flowering in late summer.
