A staple in Mediterranean gardens, lavender thrives in full sun and well-drained soil, making it perfect for borders, containers, and wildlife-friendly gardens.

This guide will provide everything you need to know about growing and caring for lavender plants, including planting techniques, maintenance, pruning, pest control, and popular varieties.

Understanding the Different Types of Lavender

There are several species of lavender, each with distinct characteristics. Choosing the right type depends on your climate, soil conditions, and intended use.

1. English Lavender (Lavandula angustifolia)

English lavender is one of the most popular and hardy varieties. It is highly fragrant and ideal for both ornamental gardens and culinary use.

Popular English Lavender Varieties

  • Hidcote – A compact variety with deep purple flowers and a strong scent.
  • Munstead – A dwarf variety with bright purple flowers and a bushy habit.
  • ‘Vera’ – Known for its exceptional oil production and fragrance.
  • ‘Miss Katherine’ – A rare pink-flowered English lavender.

2. French Lavender (Lavandula stoechas)

French lavender is recognised by its distinctive "rabbit ear" bracts at the top of the flowers. It blooms for an extended period but is less hardy than English lavender.

Popular French Lavender Varieties

  • ‘Regal Splendour’ – A striking variety with deep purple flowers and showy bracts.
  • Fathead – A compact plant with deep violet flower heads.
  • ‘Anouk’ – A well-known variety that flowers from early spring to late summer.

3. Spanish Lavender (Lavandula dentata)

Spanish lavender is heat-tolerant and has serrated, grey-green leaves with a strong fragrance. It thrives in warmer climates.

Popular Spanish Lavender Varieties

  • ‘Royal Crown’ – A long-flowering variety with dark purple bracts.
  • ‘Pure Platinum’ – A unique silver-leaved variety with soft purple flowers.

4. Lavandin (Lavandula x intermedia)

A hybrid between English and Portuguese lavender, Lavandin is prized for its larger size, stronger fragrance, and high oil content.

Popular Lavandin Varieties

  • ‘Grosso’ – One of the most widely grown varieties, known for its intense fragrance.
  • Provence – A tall, bushy variety with long flower spikes.
  • Edelweiss – A rare white-flowered variety with a rich aroma.

How to Plant Lavender

Lavender is easy to grow when given the right conditions. Proper planting ensures a healthy, long-lived plant with abundant blooms.

When and Where to Plant Lavender

  • Timing: Plant lavender in spring or early autumn so it has time to establish before winter.
  • Location: Choose a site with full sun (at least 6 hours per day) and good air circulation.
  • Soil: Well-drained, sandy or gravelly soil with a pH between 6.5 and 7.5 is ideal. Heavy clay soils should be amended with sand or grit to improve drainage.

Steps for Planting Lavender

  1. Prepare the Soil: Mix in horticultural grit or sand for better drainage.
  2. Dig a Hole: Make a hole slightly wider than the plant’s root ball.
  3. Plant at the Right Depth: Ensure the crown of the plant is level with the soil surface.
  4. Backfill and Water: Fill in the hole, firm the soil gently, and water well.
  5. Mulch with Gravel: Avoid organic mulch, which can trap moisture and cause root rot.

Propagating Lavender

Lavender is easy to propagate from cuttings, ensuring a steady supply of new plants.

Steps for Taking Lavender Cuttings

  1. Choose a Healthy Stem: Take a non-flowering shoot about 10 cm long.
  2. Remove Lower Leaves: Strip the bottom leaves to expose the nodes.
  3. Dip in Rooting Hormone (optional): Helps encourage faster rooting.
  4. Plant in Compost: Insert the cutting into well-draining compost and keep it moist.
  5. Provide Warmth: Keep cuttings in a warm, bright spot but out of direct sunlight.

Roots should develop within 4–6 weeks, after which the cuttings can be potted up.

Caring for Lavender Plants

Lavender is a low-maintenance plant that thrives with minimal care.

Light, Soil, and Water Requirements

  • Light: Full sun is essential for healthy growth and strong fragrance.
  • Soil: Poor, well-drained soil encourages more flowers and higher oil production.
  • Water: Lavender is drought-tolerant. Water newly planted lavender regularly but reduce watering once established. Avoid overwatering.

Fertiliser Needs

Lavender does not require heavy feeding. Too much nitrogen encourages leafy growth at the expense of flowers.

  • Best option: A light application of a low-nitrogen, high-potassium fertiliser in early spring.
  • Organic feeding: A handful of bone meal or wood ash improves flower production.

Pruning and Maintenance

Regular pruning keeps lavender compact, prevents legginess, and encourages better flowering.

How and When to Prune Lavender

  • Spring Pruning: Trim back lightly to remove winter damage.
  • Post-Flowering Pruning: After flowering, cut back about one-third of the plant to encourage a second flush.
  • Autumn Pruning: In colder regions, avoid heavy pruning in autumn, as this can leave plants vulnerable to frost damage.

Tip: Never cut into old, woody stems, as lavender struggles to regrow from old wood.

Common Pests and Diseases

Lavender is generally pest-resistant but may experience occasional issues.

Pests

  • Aphids – Can be removed with a blast of water or neem oil spray.
  • Spittlebugs – Harmless but can be washed off with water.

Diseases

  • Root Rot – Occurs in poorly drained soil. Prevent by planting in raised beds or pots with good drainage.
  • Powdery Mildew – Can be reduced by improving air circulation around plants.

Lavender in Garden Design

Lavender’s fragrance, drought resistance, and beauty make it a perfect addition to many garden styles.

  • Borders & Edging: English lavender is ideal for formal garden borders.
  • Wildlife Gardens: Lavender attracts bees, butterflies, and pollinators.
  • Mediterranean Gardens: Pair with rosemary, thyme, and sage for a stunning dry garden.
  • Pots & Containers: Dwarf varieties like ‘Munstead’ or ‘Hidcote’ are ideal for patios.

Cooking and Culinary Uses for Lavender

Lavender is widely used in culinary applications for its aromatic, floral flavour.

  • Herbal Teas – Brew dried flowers for a calming tea.
  • Baking – Add to biscuits, cakes, and shortbread.
  • Lavender Sugar – Infuse sugar with dried lavender for use in desserts.
  • Lavender Honey – Used in syrups and sweet dishes.
