What Are Lavender Plugs?

Lavender plugs are young plants grown in small cells until they’re ready to be transplanted into a garden or larger container. These tiny starters offer a jumpstart in growing lavender, bypassing the unpredictable germination stage of seeds.

Why Choose Plugs Over Seeds or Full-Grown Plants?

Opting for lavender plugs can be a middle ground for gardeners looking for ease without sacrificing the joy of watching their lavender grow and develop. Plugs are more cost-effective than mature plants and more reliable than seeds, making them an ideal choice for both beginners and experienced gardeners.

What Are the Best Varieties for Plugs?

The variety of lavender you choose will largely depend on your climate and the desired use of the lavender. Some popular varieties include Lavandula angustifolia (English lavender) for colder climates and Lavandula x intermedia (Lavandin) for warmer areas, both known for their fragrance and oil production.

How to Choose Based on Your Climate?

Selecting the right variety involves understanding your local climate’s limitations and opportunities. English lavender thrives in cooler environments with well-draining soil, while Spanish lavender prefers warmer, sunnier spots.

Step-by-Step Guide to Planting

  1. Prepare the planting site by loosening the soil and incorporating organic matter if necessary.
  2. Space the plugs about 18 inches apart to allow for airflow and growth.
  3. Dig a hole for each plug, ensuring it’s the same depth as the root ball but twice as wide.
  4. Remove the plug from its container, tease the roots gently, and place it in the hole.
  5. Fill the hole with soil, press firmly around the base of the plug, and water thoroughly.

How Often Should You Water Lavender Plugs?

Lavender plugs require careful attention to watering, as their young roots are particularly vulnerable to overwatering. Initially, keep the soil moist but not waterlogged until the plugs are established. Once established, lavender benefits from a less-is-more approach to watering, thriving on occasional deep watering that mimics the dry conditions of its native habitat.

What Fertiliser Is Best for Lavender?

Lavender generally prefers low-fertility conditions and may not require frequent fertilisation. If needed, opt for a slow-release, low-nitrogen fertiliser in the early spring to encourage robust growth without compromising the plant’s essential oils and fragrances.

What Soil Do Lavender Plugs Need?

Lavender thrives in well-drained, slightly alkaline soil. Preparing your garden with ample organic matter and ensuring good drainage will set the foundation for healthy growth. Whether you’re planting in the ground or in containers, the key is to ensure good drainage. Mixing gravel or sand into the planting medium can improve soil structure, preventing waterlogging and root rot.

How Much Sunlight Does Lavender Need?

Lavender plants are sun worshippers, requiring at least six to eight hours of direct sunlight daily. Full sun exposure is critical for the development of the oils that give lavender its signature fragrance and for encouraging abundant blooms. Lavender thrives in a wide range of temperatures, but it performs best in conditions ranging from 15°C to 30°C (60°F to 86°F). While lavender is resilient and can tolerate both cooler and warmer temperatures, extreme conditions can stress the plants and affect their growth and blooming.

How and When to Prune Lavender Plugs?

Pruning is essential for maintaining a compact, bushy growth habit and encouraging vigorous blooming. Begin pruning in the second year after planting, in early spring or just after the first flowering. Remove about one-third of the plant, cutting just above the woody part of the stem to promote new growth.

Tips for Maintaining Healthy Plants

  • Remove spent flowers to encourage a second bloom.
  • In late fall, give lavender a light prune to shape the plant and prepare it for winter.
  • Ensure good air circulation around the plants to prevent fungal diseases.

Common Pests and Diseases Affecting Lavender

Lavender is relatively pest and disease resistant, but it can be susceptible to root rot if overwatered. Aphids, whiteflies, and occasionally spider mites can also pose a threat.

How to Prevent and Treat Them

  • Practice proper watering techniques to avoid root rot.
  • Use organic pest control methods, such as neem oil or insecticidal soap, to manage infestations without harming the plant’s oils.
  • Ensure adequate spacing and air circulation to deter fungal diseases.

How to Encourage Your Lavender Plugs to Bloom?

To maximise blooming, ensure your lavender plugs receive ample sunlight, are planted in well-draining soil, and are pruned correctly. Additionally, avoiding excess nitrogen in fertilisers can prevent lush foliage at the expense of blooms.

Techniques for Fuller, More Vibrant Blooms

  • Deadhead spent blooms promptly to encourage new flowers.
  • Use a phosphorus-rich fertiliser sparingly to promote blooming.
  • Mulch with gravel or sand to reflect light and provide the dry, warm conditions lavender loves.

How to Protect Lavender Plugs in Winter?

Preparing lavender plugs for winter is crucial, especially in regions where temperatures drop significantly. While many varieties of lavender are hardy, young plants are more vulnerable to frost and extreme cold. Mulching with straw or using frost cloths can provide extra insulation. In very cold climates, consider potting your lavender and moving it indoors or to a protected area outdoors during the winter months.

Overwintering Tips and Techniques

  • Reduce watering in the fall to help harden off the plants.
  • Avoid heavy mulches like wood chips that retain moisture, as this can lead to root rot.
  • If grown in containers, ensure pots have good drainage and are raised off the ground to prevent waterlogging.

Can You Propagate New Plants from Plugs?

Yes, lavender plugs can serve as excellent starter points for propagation. Once your lavender plugs are established and healthy, you can propagate new plants through cuttings, taking advantage of the vigorous growth to expand your lavender collection.

Step-by-Step Propagation Guide

  1. In late spring or early summer, select healthy, non-flowering stems for cuttings.
  2. Cut a 10-15 cm (4-6 inch) length from the stem, stripping the leaves from the bottom half.
  3. Dip the cut end in rooting hormone powder to encourage root development.
  4. Plant the cutting in a mix of perlite and peat moss, ensuring good contact between the cutting and the medium.
  5. Keep the cuttings in a warm, well-lit area, maintaining moisture until roots have established, typically within 4-8 weeks.

What Are the Most Common Issues with Growing Lavender Plugs?

Growing lavender plugs can sometimes present challenges, such as root rot from overwatering, leggy growth due to insufficient sunlight, or failure to bloom, often caused by too much nitrogen.

Solutions to These Challenges

  • Ensure well-draining soil and moderate watering.
  • Provide full sun exposure and consider supplemental lighting if necessary.
  • Use low-nitrogen fertilisers sparingly and focus on phosphorus for bloom production.

How to Harvest Lavender?

The best time to harvest lavender for maximum fragrance and oil content is in the morning after the dew has evaporated but before the sun is at its peak. Cut the stems long, and gather them in small bunches to dry.

Tips for Drying and Storing Lavender

  • Hang the bunches upside down in a dark, dry, and well-ventilated area.
  • Allow the lavender to dry completely, which can take several weeks depending on the humidity.
  • Store dried lavender in airtight containers away from direct sunlight to preserve its fragrance and colour.

Uses for Homegrown Lavender

Lavender’s versatility extends beyond its beauty in the garden. Its dried flowers can be used in culinary dishes, homemade skincare products, and therapeutic applications, offering soothing and antiseptic properties. Additionally, lavender makes a beautiful addition to home décor, whether in bouquets, sachets, or wreaths, infusing spaces with its calming aroma.


Growing lavender plugs is a rewarding endeavour that enhances your garden with beauty, fragrance, and a touch of whimsy. By following these guidelines—from selecting the right variety and preparing the planting site to maintaining, pruning, and harvesting your lavender—you’ll be well on your way to cultivating a thriving lavender garden. Whether you’re a seasoned gardener or a novice, the journey of growing lavender plugs promises a delightful experience filled with aromatic blooms and vibrant colours.
