Why Grow Lavender from Seed?
Growing lavender from seed has become increasingly popular among gardeners for. Despite being more challenging than planting store-bought seedlings, the benefits are well worth the effort.
Benefits of Growing Lavender from Seed
Cost-Effective
Starting lavender from seed is a more budget-friendly option compared to purchasing established plants. A packet of seeds costs less and can yield multiple plants, allowing you to cover larger areas of your garden without breaking the bank.
Variety Selection
When growing from seed, you have access to a wider variety of lavender species and cultivars. This means you can choose specific types that best suit your climate, soil conditions, and personal preferences, creating a uniquely tailored lavender garden.
Sense of Accomplishment
There’s a special satisfaction that comes from nurturing a plant from seed to full bloom. Watching your lavender grow and thrive under your care provides a rewarding sense of accomplishment, making the entire gardening experience more enjoyable.
Challenges and Considerations
Specific Germination Conditions
Lavender seeds require precise germination conditions, including a process called stratification, where seeds are exposed to cold temperatures before planting. This step is important for successful germination, and skipping it can result in poor seedling development.
Slower Growth
Compared to buying established lavender plants, growing from seed takes longer. It requires patience and dedication, as it may take several months before your seedlings are ready to be transplanted outdoors.
Variable Germination Rates
Not all lavender seeds will germinate successfully, even under ideal conditions. It’s essential to sow more seeds than you need to account for any that don’t sprout.
According to research conducted by Research Gate, seeds were stored at room temperature in a dark environment during the study period. The research was completed under controlled conditions.
According to the obtained values, the seeds have a long and oval structure, with an average length of 2.068 mm, a width of 0.944 mm, a surface area of 1.646 mm², and a thousand-grain weight of 0.0352 g.
Lavender Varieties
There are numerous lavender species, each with its unique characteristics. Choosing the right variety is essential for ensuring your plants thrive in your specific growing conditions.
Different Types of Lavender
English Lavender (Lavandula angustifolia)
Known for its sweet fragrance and bright purple flowers, English lavender is hardy and adaptable, making it a popular choice for gardens worldwide.
French Lavender (Lavandula dentata)
With its serrated leaves and distinctive ‘ears’ on the flower spikes, French lavender adds a touch of elegance and is well-suited for warmer climates.
Spanish Lavender (Lavandula stoechas)
Recognizable by its pineapple-shaped flower heads topped with colorful bracts, Spanish lavender is both visually striking and highly aromatic.
Choosing the Right Variety
Select a lavender variety that matches your climate and soil conditions. English lavender, for instance, is more tolerant of cold weather, while French and Spanish lavenders thrive in warmer, drier environments.
Preparing to Grow Lavender from Seed
Before planting, gather all necessary supplies and understand the specific requirements for successful germination.
Gathering Supplies
To grow lavender from seed, you’ll need:
- Quality lavender seeds
- Seed-starting soil mix
- Seed trays or small pots
- Clear plastic dome or plastic wrap (for humidity)
- Grow lights or a sunny windowsill
- Labels for seed trays
Ensure you use high-quality seeds from a reputable source to increase your chances of successful germination.
Germination Requirements
Lavender seeds have specific needs regarding soil, temperature, and moisture to germinate properly.
Soil Type and pH
Use a well-draining seed-starting mix with a pH between 6.5 and 7.5. Lavender prefers alkaline to neutral soil conditions.
Temperature and Light Conditions
Lavender seeds require warm temperatures (around 70°F) and plenty of light to germinate. If natural light is insufficient, use grow lights to provide 12-16 hours of light daily.
Moisture Requirements
Keep the soil consistently moist but not waterlogged. Overwatering can lead to damping off, a fungal disease that kills seedlings.
How to Grow Lavender from Seed
Follow these steps to ensure your lavender seeds germinate and grow into healthy plants.
Sowing the Seeds
When to Start Planting
Start your lavender seeds indoors about 10-12 weeks before your area’s last expected frost date.
Seed Stratification Process
Lavender seeds need cold stratification to germinate. Place seeds on a damp paper towel, fold it, and put it in a sealable plastic bag. Refrigerate for 3-4 weeks before planting.
Sowing Seeds Indoors
Fill seed trays or pots with seed-starting mix, sprinkle seeds on the surface, and lightly press them into the soil. Cover with a thin layer of soil and mist with water. Use labels to identify different varieties.
Caring for Seedlings
Light and Temperature Needs
Place seedlings under grow lights or on a sunny windowsill, ensuring they receive 12-16 hours of light daily. Maintain a temperature around 70°F.
Watering Tips
Water seedlings carefully to keep the soil moist but not soggy. Avoid overhead watering to prevent fungal diseases. Use a spray bottle for gentle watering.
Transplanting Seedlings to Larger Pots
Once seedlings have several sets of true leaves and are about 2-3 inches tall, transplant them into larger pots filled with well-draining potting mix.
Transplanting Outdoors
When and How to Transplant
Transplant seedlings outdoors after the last frost date when temperatures are consistently warm. Choose a sunny location with well-draining soil.
Preparing the Garden Bed
Prepare the garden bed by loosening the soil and amending it with compost if necessary. Space plants 12-18 inches apart to allow for proper air circulation.
Hardening Off Process
Gradually acclimate seedlings to outdoor conditions by placing them outside for a few hours each day, increasing the time over a week.
Maintaining and Caring for Lavender Plants
Proper care ensures your lavender plants remain healthy and productive.
Watering and Feeding
Watering Schedule
Water lavender deeply but infrequently, allowing the soil to dry out between waterings. Overwatering can lead to root rot.
Fertilization Tips
Lavender doesn’t require heavy feeding. Apply a balanced, slow-release fertilizer in spring or use compost to provide nutrients.
Pruning and Harvesting
Pruning Lavender
Prune lavender after flowering to maintain its shape and encourage new growth. Cut back about one-third of the plant, avoiding cutting into old wood.
Harvesting Tips
Harvest lavender when the flower buds are just opening for the best fragrance and oil content. Cut stems early in the morning and hang them upside down to dry in a cool, dark place.
Dealing with Pests and Diseases
Common Pests and Diseases
Watch for pests like aphids and spider mites and diseases like root rot and lavender shab. Proper spacing, good air circulation, and well-draining soil help prevent these issues.
Organic and Chemical Control Methods
Use organic pest control methods like insecticidal soap or neem oil. For severe infestations, consider chemical options as a last resort.
