How to Revitalize a Fading Lavender Plant

Lavender plants, known for their low maintenance nature and longevity of up to 15 years, require specific conditions to thrive. Originating from the Mediterranean region of Europe, lavenders have adapted to a unique set of circumstances. If your lavender plant is showing signs of distress, it’s crucial to diagnose the underlying issue and take steps to revive it. In this article, we will explore common problems that beset lavender plants and provide effective solutions to restore their health and vibrancy.

Identify the Root Cause

A dying lavender plant can suffer from various ailments, including root rot, leggy growth with yellow leaves, woody stems, lack of sunlight, or improper planting techniques. Each issue requires specific remedies to revive your lavender successfully. Let’s delve into each problem and its respective solution.

Root Rot (Lavender Turning Brown and Drying Out)

Symptoms: Drooping appearance with browning or yellowing foliage.

Causes: Overwatering, slow-draining soil, excess humidity, overcrowding, or organic debris near the plant.

Lavenders, native to the dry, sandy regions of the Mediterranean coast, thrive in infrequent watering, well-draining soil, ample sunlight, and good airflow. Overwatering lavenders, especially in soils that retain moisture, can lead to root rot.

To revive a lavender plant suffering from root rot, scale back the watering schedule and protect potted plants from rainfall. Remove any organic material, such as dead leaves or mulch, surrounding the lavender, as they retain moisture and contribute to root rot. Inspect the roots for any soft, rotting sections and trim them with sterilized pruners. Replant the lavender in a sunny location with new soil that has been amended with sand or gravel to enhance drainage. This will replicate the ideal soil conditions of its native environment.

Leggy Growth and Yellow Foliage

Symptoms: Sparse flowers, leggy stems, and yellow leaves.

Causes: Soil high in nitrogen, excessive fertilizer usage, lack of pruning.

Lavenders thrive in low to medium fertility soils, resembling the sandy or gravelly conditions of their native habitat. Planting lavenders in nutrient-rich soil can result in leggy growth and reduced flowering. Avoid fertilizing lavenders, as it can turn the foliage yellow and make the plant more prone to diseases.

To revive leggy lavenders with yellow foliage, cease fertilization immediately. Transplant the lavender to a pot or amend the garden soil with sand or gravel to create a balanced soil fertility. Prune back the leggy growth in early spring or late fall, removing only the top third of flexible growth. Patience is key during the revival process, as it may take some time for the lavender to fully recover.

Woody Growth

Symptoms: Untidy appearance, reduced flowering, vulnerability to splitting.

Causes: Natural progression as lavenders age, lack of annual pruning.

All lavenders gradually develop woody stems over time. However, regular pruning can slow down the formation of woody growth. Proper pruning ensures the longevity of lavenders, with English varieties lasting up to 15 years compared to French lavenders’ lifespan of 4-5 years.

To revive woody lavenders, pruning is essential. Be cautious not to cut into the woody growth, as it is unproductive and won’t support new growth or flowering. Focus on trimming the top third of the green, flexible growth, shaping the lavender into a mound to withstand weather conditions. The best time to prune lavender is in early spring or late fall, before or after the flowering season.

If woody lavender fails to revive, consider replacing it with a new plant or propagate new ones from cuttings. Taking cuttings in early spring allows for easy propagation without the need for root hormone powder. Watch this helpful YouTube video for a visual explanation of lavender propagation from cuttings.

Reviving Lavenders in Pots or Containers

Issues: Insufficient pot size, lack of drainage holes.

Potted lavenders can struggle due to small containers or inadequate drainage. The ideal pot size should be at least 16 inches in diameter to accommodate the plant’s roots and provide insulation. Drainage holes in the base are crucial to prevent water from pooling, as this can lead to root rot. Avoid using drip trays, as they retain moisture and promote unfavorable conditions for lavenders.

For lavenders in pots, always use soil with a porous texture and good drainage to mimic their natural habitat. Remember to move the pot to a different location, such as a lawn, after watering to prevent water from trickling over patios or indoor areas. This helps maintain the proper moisture levels for the lavender.

Lavenders in the Shade

Issue: Insufficient sunlight.

All lavender species require full sun to reach their full potential, producing vibrant blooms, essential oils, and captivating fragrances. Insufficient sunlight can result in stunted growth and even death for lavenders. If your lavender has been in the shade, transfer it to a sunny spot as soon as possible. Lavenders need sun throughout the year, including during the winter dormancy period.

Reviving lavender that has been deprived of sunlight may require time and patience. Ensure you follow best care practices for lavenders to provide the plant with a chance to recover.

Reviving Lavenders After Winter

Issue: Frost damage.

Not all lavenders can withstand freezing temperatures and frost. While English and hybrid lavenders are cold-hardy, French lavenders are more delicate and require winter protection in cold climates. Frost-damaged lavenders can be challenging to revive, and it may be necessary to replace them. However, dormant lavenders should be given a chance to recover in early spring before making any decisions.

For detailed instructions on caring for lavenders over winter, refer to our comprehensive article. We also have a specific guide on caring for French lavenders, which require additional care during the winter months.

Key Takeaways:

  • Overwatering and root rot are common causes of dying lavenders. Recreate the conditions of their Mediterranean environment by providing well-draining soil, infrequent watering, and ample sunlight.
  • Leggy growth and yellow foliage result from lavenders planted in nutrient-rich soil or excessive fertilizer usage. Transplanting lavenders or amending the soil with sand or gravel restores proper soil fertility.
  • Woody growth is a natural progression for lavenders. Regular pruning reduces woody growth and enhances longevity.
  • Lavenders in pots or containers need sufficient space and proper drainage. Use pots at least 16 inches in diameter and ensure there are drainage holes at the base.
  • Lavenders require full sun to thrive. Transfer lavenders from shaded areas to sunny spots for optimal growth.
  • French lavenders require winter protection, while English lavenders are cold-hardy. Assess winter damage in early spring before taking further action.

Reviving dying lavenders requires attention to their specific needs and conditions. By implementing the appropriate solutions and following best care practices, you can enable your lavender plants to regain their health and thrive once again.
