If you’re looking to add a fragrant touch to your garden, patio, or balcony, potted lavender is the perfect choice. With its scented flowers and foliage, lavender offers a wide range of options to suit your preferences. In this comprehensive guide, you’ll discover everything you need to know to keep your lavender plants thriving and blooming.
As a professional gardener with over twenty years of experience in California, I’ve planted and maintained numerous lavender plants. I’ve witnessed the abundance and fragrance of lavender firsthand during the fifteen years my mother spent in Sonoma County. In Sonoma County, June is lavender month, and the scent of lavender fills the air wherever it grows. With my extensive knowledge of lavender, I’m excited to share what I’ve learned with you.
Growing Potted Lavender
Lavender thrives in warm and sunny conditions. In milder climates, it is a perennial and can be grown in USDA zones 5 to 9. However, not all lavenders are suitable for all zones, so make sure to check which varieties are recommended for your specific growing zone. Lavender can be easily managed in containers and planted alongside other plants with similar needs, making it ideal for small spaces.
Choosing the Best Lavender for Pots
There are many lavender species, varieties, and hybrids that grow well in containers. Some popular types include English Lavender (Lavandula angustifolia), French Lavender (Lavandula dentata), and Spanish Lavender (Lavandula stoechas). It’s important to choose lavenders that are suitable for your climate, as some are more heat tolerant, others more tolerant of humidity, and some more cold tolerant.
Pots for Growing Lavender
When selecting a pot size, consider the growth rate of lavender. Smaller lavenders will thrive in smaller pots, while larger varieties will require more substantial containers. Ceramic, fiberglass, resin, and terracotta pots all work well for growing lavender. Regardless of the material, ensure there is at least one drainage hole at the bottom to allow excess water to escape.
Lavender Flowers
Lavender typically produces violet to purple flowers on long stems, although white and pink varieties are also available. The size and shape of the flower head can vary among different lavender types. Bloom times vary as well, with some lavenders flowering in early spring, most in summer, and a few even into fall. Lavender flowers attract pollinators, making them a valuable addition to any garden.
Lavender Sunlight Requirements
Lavender plants in pots require full sun, with at least six hours of direct sunlight daily. However, in desert areas with intense sun and heat, such as Palm Springs, Joshua Tree, and Phoenix, special care must be taken. It’s crucial to provide shade or bring potted lavender indoors during extreme heat. Remember to gradually acclimate your lavender to outdoor conditions after periods of indoor cultivation.
Watering Lavender
Watering lavender in pots is a delicate balancing act. As a general rule, water only when the soil has almost completely dried out. Smaller pots and newly planted lavenders will require more frequent watering compared to mature plants or those growing in the ground. Good soil drainage is essential to prevent overwatering, which can be detrimental to lavender plants. During winter, lavender requires minimal supplemental watering.
Temperature/Humidity
Most lavenders are hardy in USDA zones 5 to 9 and can tolerate a range of temperatures. However, they do not fare well in humid climates. Lavender prefers low humidity and requires good air circulation. Excessive humidity and lack of air movement can lead to fungal and bacterial diseases. To ensure healthy growth, plant lavender in a sunny, well-ventilated area with low humidity.
Fertilizer for Lavender in Pots
Lavender plants typically do not require fertilizer. While I have never fertilized lavender plants growing in pots, adding a thin layer of compost on top of the soil every other spring can provide natural nourishment. Avoid excessive fertilization, as it may promote excessive growth at the expense of flower production.
Pruning Lavender
Regular pruning is beneficial for lavender plants as it promotes new growth, flowering, and an overall pleasing shape. Deadheading, the removal of spent flower stems, encourages another bloom cycle. Pruning should be done in spring, taking care not to cut into the woody part of the stems. A well-pruned lavender plant will maintain its appearance and keep blooming beautifully.
How to Keep Lavender Flowering
Sunlight is crucial for lavender to flower successfully. Ensure your lavender is planted in the right conditions, particularly regarding sunlight exposure. After the initial bloom cycle, deadhead the flowers by removing them where the foliage starts. This practice not only keeps the plant looking attractive but may also stimulate a second bloom towards the end of the season.
When to Plant Lavender
For the best results, plant lavender during the growing season, preferably in spring or summer. Early fall is also acceptable in more temperate climates.
Potting Soil for Lavender in Pots
Lavender plants thrive in chunky, well-drained soil. Adding a few handfuls of organic matter to the potting mix can improve drainage and provide natural nourishment. If you require further information on the ideal potting mix for lavender, refer to the link in the category below.
How to Plant Lavender in a Pot
Planting lavender in a pot is a straightforward process. Avoid piling too much compost on top of the soil, as it can retain excessive moisture and lead to root rot. Instead, apply a light layer. For detailed step-by-step instructions, soil mix recommendations, and aftercare guidance, refer to the post on “Planting Lavender in Pots.”
What to Plant with Lavender in Pots
Lavender can be planted on its own to create a stunning focal point or combined with other sun-loving, low-water plants that share similar growing conditions. Suitable companions for lavender include penstemon, salvias, rudbeckias, echinacea, yarrow, rosemary, sage, oregano, thyme, marigolds, and zinnias. For more ideas, check out our post on “Rosemary Companion Plants.”
Propagating Lavender in Pots
Lavender can be propagated by stem cuttings. Take tip cuttings, the tender ends of the lavender stems, measuring around 3-6 inches in length. Plant the cuttings in a sandy soil mix or a blend of potting soil and horticultural sand, pumice, or perlite. Lightening the mix facilitates root growth.
Lavender in Pots Over Winter
Bringing potted lavender indoors during winter is a viable option, especially in regions with harsh winters. Place the plant in a well-lit area where it can receive ample sunlight, and allow the soil to dry out between waterings.
Common Lavender Issues
Lavender plants are generally resilient and not prone to major pest infestations. However, watch out for spittlebugs, spider mites, and aphids. Additionally, avoid damp conditions, heavy soil, insufficient light, and lack of air circulation, as these factors can lead to fungal and bacterial diseases. Ensure that your lavender plant is placed in a sunny location with good airflow and well-drained soil.
Growing Lavender Indoors
Growing lavender indoors requires ample light and infrequent watering. If you live in a climate that isn’t suitable for English Lavender, you can still enjoy it by cultivating it indoors. Choose a well-draining potting mix and provide the plant with bright light, ideally near a south-facing window. Reduce watering frequency during the winter months.
Growing lavender in pots is a rewarding experience when you choose the right lavender variety, provide optimal conditions, and follow proper care guidelines. Lavender’s vibrant flowers, soothing fragrance, and versatility make it a delightful plant to cultivate. Embrace the joy of potted lavender gardening and create a more beautiful world!
Happy gardening,
