How to Graft and Care for Grafted Lavender Plants

by

Grafting lavender plants is an effective way to propagate new plants that retain desirable traits such as fragrance, color, and growth habit. Proper grafting and care ensure healthy, vigorous lavender plants that flourish in your garden. This guide provides step-by-step instructions on how to graft lavender and maintain your grafted plants for optimal growth.

Understanding Lavender Grafting

Lavender grafting involves joining a scion (the upper part of the plant) onto a rootstock (the root portion). This technique allows gardeners to combine the best traits of different lavender varieties, such as increased fragrance or disease resistance. Grafting is typically performed on mature plants during the early spring or late winter when the plants are still dormant.

Steps to Graft Lavender

Follow these steps to successfully graft lavender:

  • Select healthy parent plants: Choose a vigorous rootstock and a desirable scion from healthy, disease-free plants.
  • Prepare the grafting tools: Use sharp, sterilized knives or grafting tools for clean cuts.
  • Make the cuts: Cut the rootstock and scion at matching angles to ensure a good fit.
  • Join the parts: Fit the scion onto the rootstock, ensuring cambial layers align perfectly.
  • Secure the graft: Wrap the graft union with grafting tape or a rubber band to hold it tightly.
  • Seal the graft: Apply grafting wax or sealant to prevent moisture loss and infection.

Care and Maintenance of Grafted Lavender

Proper care after grafting is crucial for the success and growth of your lavender plants. Here are some essential tips:

  • Keep the grafted plant in a sheltered location: Protect it from strong winds and direct harsh sunlight during the initial healing phase.
  • Maintain consistent moisture: Water regularly but avoid overwatering, which can cause root rot.
  • Monitor for pests and diseases: Check the graft union and leaves frequently for signs of problems.
  • Remove any new growth below the graft: To ensure energy goes into the grafted part, prune any shoots emerging below the graft union.
  • Gradually acclimate the plant: Once the graft has taken, slowly expose it to outdoor conditions to prevent shock.

Long-term Care Tips

For healthy, productive lavender plants:

  • Prune regularly: Trim back spent flowers and prune to maintain shape and promote bushiness.
  • Ensure proper drainage: Lavender dislikes waterlogged soil; plant in well-draining soil or raised beds.
  • Fertilize sparingly: Use a light application of balanced fertilizer in spring.
  • Protect during winter: In colder climates, provide mulch or cover to protect the roots from freezing.

Grafting lavender can be a rewarding process that results in beautiful, fragrant plants for your garden. With patience and proper care, your grafted lavender will thrive and provide enjoyment for years to come.
