Choosing the Right Lavender Variety for Container Life
Not all lavenders are created equal when it comes to container gardening. While most types appreciate well-drained soil and plenty of sun, some are simply better suited for the confined space of a pot. Understanding the different types will help you pick a winner.
When selecting a variety, consider its mature size and growth habit. Dwarf varieties or those with a more compact form are often the best choices for pots, as they won’t quickly outgrow their home.
English Lavender (Lavandula angustifolia)
Often considered the “true” lavender, English lavender varieties are incredibly popular for their strong fragrance and beautiful, dense flower spikes. They are also remarkably cold-hardy, making them excellent choices for many climates.
- ‘Hidcote’: A classic, compact variety with deep purple flowers and silvery foliage. Reaches about 18-24 inches tall.
- ‘Munstead’: Another compact favorite, known for its vibrant lavender-blue flowers and exceptional hardiness. Grows to about 18 inches.
- ‘Lady’: A quick-to-bloom variety from seed, reaching about 10-12 inches, perfect for smaller pots.
These varieties are typically more tolerant of cooler temperatures, making them suitable for year-round outdoor display in many zones, or easier to overwinter.
French Lavender (Lavandula dentata)
French lavender is characterized by its toothed, lacy leaves and distinctive “bunny ear” bracts atop its flower spikes. It has a slightly milder, more herbaceous scent compared to English lavender.
- ‘Goodwin Creek Grey’: Known for its attractive silver-grey foliage and long blooming season. Can grow quite large, so select a spacious pot.
French lavenders are less cold-hardy than their English counterparts, making them ideal for gardeners in warmer climates or those who plan to bring their pots indoors during winter.
Spanish Lavender (Lavandula stoechas)
Spanish lavender is instantly recognizable by its unique pineapple-shaped flowers topped with prominent, colorful bracts, often resembling butterfly wings. It has a more camphor-like scent.
- ‘Anouk’: A popular compact variety with dark purple flowers and striking deep purple bracts.
- ‘Otto Quast’: Known for its large, deep purple flowers and good heat tolerance.
Like French lavender, Spanish varieties prefer warmer climates and may need winter protection in colder regions. Their unique appearance makes them a delightful addition to any container garden.
Selecting the Perfect Pot and Potting Mix
The right container and soil are absolutely critical for successful lavender cultivation. Lavender hates “wet feet,” so proper drainage is non-negotiable.
Choosing the Right Container Material and Size
When it comes to pots, material matters! Terracotta or unglazed ceramic pots are often the best choice for lavender. These materials are porous, allowing excess moisture to evaporate through the pot walls, which helps prevent root rot.
Plastic or glazed ceramic pots can retain too much moisture, so if you use them, be extra vigilant with your watering. Whatever material you choose, ensure the pot has at least one large drainage hole at the bottom.
For size, start with a pot that’s at least 12-16 inches in diameter for a single plant. As your lavender grows, you may need to repot it into a larger container every 1-2 years. A larger pot offers more room for root development and better moisture stability.
The Ideal Potting Mix for Lavender
Lavender thrives in lean, well-draining soil that mimics its native Mediterranean environment. Avoid rich, heavy potting mixes designed for moisture-loving plants. Instead, aim for a fast-draining, slightly alkaline mix.
Here’s a simple recipe for a great potting mix:
- 2 parts high-quality potting soil: Look for one that’s labeled for cacti, succulents, or herbs.
- 1 part perlite or coarse sand: This dramatically improves drainage and aeration.
- 1 part grit or small gravel: Adds weight and further enhances drainage.
- Optional: a handful of horticultural lime: If your base potting soil is acidic, lime will help raise the pH to lavender’s preferred slightly alkaline range (6.5 to 7.5).
Mix these components thoroughly before planting. This custom blend will provide the perfect environment for healthy root growth and prevent waterlogging, which is crucial when growing lavender in pots outdoors.
Growing Lavender in Pots Outdoors: Essential Care Tips
Once you have your chosen lavender variety and the perfect pot, it’s time to ensure it receives the care it needs to flourish. Lavender is generally low-maintenance, but a few key elements are vital for success.
Sunlight Requirements for Thriving Lavender
Lavender absolutely adores sunshine. To produce abundant blooms and maintain its compact, bushy form, your potted lavender needs at least 6-8 hours of direct sunlight per day. More is even better!
Position your pots in the sunniest spot on your patio, balcony, or garden. If you notice leggy growth or sparse flowering, it’s a clear sign your plant isn’t getting enough light. You might need to move its location or consider supplemental lighting if growing indoors temporarily.
Airflow and Spacing
Good air circulation is important for preventing fungal diseases, especially in humid climates. Ensure your potted lavender isn’t crammed too close to other plants or against a wall. Give it some breathing room!
If you have multiple lavender pots, space them out to allow air to flow freely around the foliage. This simple step can make a big difference in plant health.
Fertilizing Your Potted Lavender
Remember that lavender prefers lean soil. Unlike many plants, it doesn’t need heavy fertilization. In fact, too much nitrogen can lead to lush foliage but fewer flowers, and can even make the plant more susceptible to disease.
If you’ve used a good quality potting mix with some compost, your lavender may not need any fertilizer for its first year. If you do choose to fertilize, opt for a balanced, slow-release granular fertilizer or a liquid feed with a lower nitrogen (N) content, applied sparingly in early spring. A single application is usually sufficient for the entire growing season.
Watering Wisdom for Potted Lavender
Watering is arguably the trickiest part of keeping potted lavender happy. Overwatering is the most common cause of failure, leading to root rot and plant demise. Underwatering, while less immediately fatal, will also stress your plant.
How to Water Potted Lavender Correctly
The golden rule for watering lavender in pots is to let the soil dry out thoroughly between waterings. Don’t water on a schedule; instead, check the soil moisture regularly.
Here’s how to do it:
- Stick your finger into the soil: Insert your finger about 2-3 inches deep. If the soil feels dry at that depth, it’s time to water. If it still feels moist, wait a few more days.
- Water deeply: When you do water, soak the soil until water drains freely from the bottom of the pot. This ensures the entire root ball gets hydrated.
- Avoid overhead watering: Try to water the soil directly, rather than spraying the foliage. Wet leaves, especially in humid conditions, can encourage fungal issues.
Factors like pot size, material, weather, and plant size will all influence how often your lavender needs water. In hot, sunny weather, you might water every 2-3 days. In cooler, overcast periods, it could be once a week or less.
Signs of Overwatering and Underwatering
Knowing what to look for can help you adjust your watering habits:
- Overwatering: Yellowing leaves, wilting despite moist soil, soft stems, and a musty smell from the soil are all signs of too much water and potential root rot. If you see these, stop watering immediately and let the soil dry out completely. You may even need to repot into fresh, dry soil.
- Underwatering: Drooping leaves that feel crisp, greyish foliage, and stunted growth indicate your plant is thirsty. A good deep watering should perk it up quickly.
Remember, it’s always better to err on the side of slightly underwatering than overwatering when it comes to lavender.
Pruning for Prolific Blooms and Healthy Plants
Pruning is essential for maintaining a compact, bushy shape, encouraging more flowers, and preventing your lavender from becoming woody and leggy. Don’t be afraid to snip!
When and How to Prune Your Potted Lavender
There are two main times to prune lavender:
- After the first flush of blooms (mid-summer): Once your lavender has finished its main bloom cycle, deadhead the spent flower stalks. You can also give the plant a light trim, removing about 1/3 of the current year’s growth. This encourages a second, smaller flush of blooms and maintains a good shape.
- In early spring (before new growth emerges): This is the most important pruning of the year. Cut back your lavender by about 1/3 to 1/2 of its size, focusing on removing any dead or woody stems. Aim to maintain a rounded, compact shape. Avoid cutting back into old, woody stems that have no green leaves, as these often won’t regrow.
Use clean, sharp pruning shears to make clean cuts. Regular pruning is key to ensuring your lavender remains vigorous and floriferous year after year.
Overwintering Your Potted Lavender
While some English lavender varieties are quite cold-hardy, potted plants are always more vulnerable to freezing temperatures than those in the ground. The soil in pots freezes much more quickly and deeply.
Winter Protection for Colder Climates
If you live in a region with harsh winters (USDA Zones 6 and below, or if your variety is less hardy), you’ll need to provide some winter protection for your potted lavender.
Here are your options:
- Bring Indoors: The safest option is to bring your potted lavender indoors before the first hard frost. Place it in a cool, bright spot (like an unheated sunroom or garage with windows). Reduce watering significantly – just enough to keep the soil from completely drying out. The plant will go dormant.
- Insulate Outdoors: If you prefer to keep it outside, group pots together against a warm, south-facing wall. Wrap the pots in burlap, bubble wrap, or blankets to insulate the roots. You can also mulch heavily around the base of the plant.
- Bury the Pot: In some cases, you can dig a hole in the garden and sink the entire pot into the ground, covering the rim with soil. This provides excellent insulation for the root ball.
No matter your method, ensure adequate drainage to prevent root rot during wet winter periods. Even dormant plants can suffer from too much moisture.
Troubleshooting Common Potted Lavender Problems
Even with the best care, sometimes issues arise. Knowing how to identify and address common problems can save your cherished lavender plant.
Yellowing Leaves and Leggy Growth
Yellowing leaves are most often a sign of overwatering or poor drainage. Re-evaluate your watering schedule and check your potting mix. Ensure water isn’t sitting in a saucer beneath the pot for extended periods.
Another cause can be a lack of sunlight. If your lavender is getting less than 6 hours of sun, leaves may yellow and growth will be weak.
Leggy growth, where stems are long and sparse with few leaves, is almost always due to insufficient sunlight. Move your pot to a sunnier location. It can also be a sign of inadequate pruning – remember to prune back about 1/3 in early spring to encourage bushier growth.
Pests and Diseases
Lavender is generally quite resistant to pests due to its strong essential oils. However, occasionally you might encounter:
- Aphids: Small, soft-bodied insects that cluster on new growth. Blast them off with a strong stream of water or treat with insecticidal soap.
- Whiteflies: Tiny white insects that fly up when disturbed. Use sticky traps or insecticidal soap.
- Spittlebugs: Produce frothy white “spit” on stems. Harmless, just unsightly. Rinse them off with water.
Diseases are usually linked to environmental stress, primarily too much moisture. Root rot is the most common disease, caused by overwatering and poor drainage. Symptoms include wilting, yellowing, and eventual plant collapse. If caught early, repotting into fresh, dry, well-draining soil might save the plant.
Fungal issues like powdery mildew can occur in humid conditions with poor air circulation. Ensure good spacing and airflow. Remove affected leaves and consider a fungicide if severe.
Regular inspection of your plants will help you catch any problems early, making them much easier to manage.
Frequently Asked Questions About Growing Lavender in Pots Outdoors
Here are some common questions gardeners ask about cultivating lavender in containers.
Can I bring my potted lavender indoors for winter?
Yes, absolutely! Bringing your potted lavender indoors is an excellent way to protect it from harsh winter conditions, especially for less hardy varieties or in colder climates. Place it in a cool, bright spot (like an unheated sunroom or garage with windows) and reduce watering significantly. It will likely go dormant, losing some leaves, but will revive in spring.
Why are my lavender flowers turning brown?
Brown flowers are usually a natural part of the plant’s life cycle – they’ve simply finished blooming. Deadheading these spent flowers encourages the plant to produce more blooms and helps maintain its neat appearance. If the entire plant is browning, it could indicate severe stress, such as extreme overwatering leading to root rot, or severe underwatering.
How often should I fertilize potted lavender?
Lavender is not a heavy feeder and generally thrives in lean soil. For potted lavender, a single application of a balanced, slow-release granular fertilizer with a lower nitrogen content in early spring is usually sufficient. Avoid over-fertilizing, especially with high-nitrogen feeds, as this can promote leafy growth at the expense of flowers and weaken the plant.
What are the best companion plants for potted lavender?
When selecting companion plants for potted lavender, choose those with similar needs: full sun and well-draining soil. Good choices include other Mediterranean herbs like rosemary, thyme, and oregano. Succulents and sedums also make excellent companions due to their preference for dry conditions. Avoid plants that require frequent watering or rich, moist soil, as this will conflict with lavender’s needs.
