Can you plant lavender seeds in the fall – Successfully growing lavender from seed requires understanding its planting seasonality. While spring is traditionally favored, fall planting offers unique advantages and challenges. This article explores the nuances of fall lavender cultivation, covering soil preparation, sowing techniques, seedling care, and illustrative examples of successful fall plantings.
Lavender Planting Seasonality, Can you plant lavender seeds in the fall

The ideal time for planting lavender seeds varies significantly depending on the climate and region. Generally, warmer climates with mild winters allow for fall planting, while colder regions are better suited for spring planting. Fall planting, in suitable climates, can provide a head start, allowing seedlings to establish strong root systems before the next growing season. However, it also carries risks associated with harsh winter conditions.
Spring planting, while potentially delaying flowering, often results in higher germination and survival rates in colder areas, mitigating the risks of winter damage.
Germination rates can vary. Fall-planted seeds might show lower initial germination due to cooler temperatures, but spring-planted seeds can be more susceptible to competition from weeds and pests. Ultimately, the success of fall planting versus spring planting hinges on the specific climatic conditions.
| Climate | Germination Rate (Fall) | Germination Rate (Spring) | Plant Survival Rate (Fall) | Plant Survival Rate (Spring) | Flowering Time (Fall Planting) | Flowering Time (Spring Planting) |
|---|---|---|---|---|---|---|
| Mediterranean | 70-80% | 80-90% | 85-95% | 90-95% | Late Spring/Early Summer | Mid-Summer |
| Temperate | 50-60% | 70-80% | 60-70% | 80-90% | Mid-Summer | Late Summer |
| Continental | 30-40% | 60-70% | 40-50% | 70-80% | Late Summer/Early Autumn | Mid-Autumn |
Preparing the Soil for Fall Planting
Successful fall lavender planting begins with proper soil preparation. Lavender thrives in well-draining, slightly alkaline soil (pH 6.5-7.5). Heavy clay soils should be amended with organic matter like compost to improve drainage and aeration. Sandy soils might benefit from the addition of peat moss to increase water retention.
- Clear the area: Remove weeds, rocks, and debris.
- Test the soil: Determine pH and nutrient levels. Amend as needed.
- Till the soil: Loosen the soil to a depth of 12-18 inches.
- Incorporate organic matter: Mix in compost or other organic amendments.
- Improve drainage: Add gravel or other drainage materials to heavy clay soils.
A well-drained soil is crucial for preventing root rot, a common problem for lavender, especially during the fall and winter months when rainfall can be higher.
Sowing Lavender Seeds in Fall
Lavender seeds can be sown directly outdoors in the fall or started indoors for later transplanting. Direct sowing is simpler but might result in lower germination rates. Starting indoors provides more control over the environment, increasing the chances of successful germination.
- Direct sowing: Sow seeds about ⅛ inch deep and 1-2 inches apart.
- Starting indoors: Sow seeds in seed trays filled with seed-starting mix. Keep moist and warm until germination.
- Protection: Newly sown seeds benefit from a light mulch layer (e.g., straw) to protect them from harsh weather.
Challenges include unpredictable weather, potential for fungal diseases, and rodent damage. Solutions involve using row covers for protection against frost, employing fungicides as needed, and protecting seeds from rodents with mesh coverings.
Fall Lavender Seedling Care
Fall-planted lavender seedlings face threats like frost, pests (aphids, spider mites), and fungal diseases. Careful watering is crucial, avoiding both overwatering and underwatering. Mulching helps regulate soil moisture and temperature, protecting the seedlings from extreme weather conditions.
- Watering: Water deeply but infrequently, allowing the soil to dry slightly between waterings.
- Mulching: Apply a 2-3 inch layer of mulch to retain moisture and suppress weeds.
- Pest and disease control: Monitor regularly for pests and diseases and take appropriate action.
- Monitoring: Regularly check for signs of stress, such as wilting or discoloration.
Illustrative Examples of Fall-Planted Lavender
Successful fall planting depends on various factors. In a Mediterranean climate with well-draining soil, ‘Provence’ lavender thrives with minimal care. In a temperate climate, ‘Hidcote’ lavender benefits from a protective mulch layer during winter. In a continental climate, ‘Munstead’ lavender might require more winter protection.
‘Provence’ lavender displays a robust growth habit, with silvery-green foliage and fragrant purple flowers. ‘Hidcote’ offers compact growth, dark purple flowers, and a strong fragrance. ‘Munstead’ is known for its compact size, rich purple flowers, and tolerance to colder temperatures. Healthy seedlings exhibit strong stems, vibrant green leaves, and an overall vigorous appearance. Unhealthy seedlings might show pale or yellow leaves, weak stems, and stunted growth.
FAQ Overview: Can You Plant Lavender Seeds In The Fall
What types of lavender are best suited for fall planting?
English lavender (Lavandula angustifolia) and its cultivars generally tolerate fall planting better than other types. However, regional climate plays a crucial role.
How deep should I plant lavender seeds in the fall?
Planting lavender seeds in the fall is a viable option in many climates, offering a head start for spring blooms. The success often depends on your specific region’s weather, much like the considerations for planting other seeds; for instance, you might wonder, as discussed in this article on can you plant guava seeds , about optimal conditions.
Returning to lavender, ensuring proper soil drainage and protection from harsh winter conditions is key for successful fall planting.
Plant seeds about twice their diameter deep, typically around 1/4 inch. Avoid planting too deep, as this can hinder germination.
What if my fall-planted lavender seedlings don’t germinate?
Several factors could be at play: poor soil drainage, incorrect seed depth, or insufficient sunlight. Review your preparation and planting methods, and consider starting seeds indoors next time.
How do I protect my fall-planted lavender from frost?
Use a protective covering such as a cold frame or row cover during periods of expected frost. Mulching also helps insulate the soil.
