Understanding Why You Might Need to Remove Lavender
Before diving into the “how,” let’s briefly touch on the “why.” Understanding the common reasons for removal can help you approach the task with the right mindset and ensure you don’t repeat the same challenges.
Often, gardeners decide to remove lavender because of overcrowding. A small plant can grow surprisingly large, dominating a space or shading out smaller neighbors. Other times, the plant itself might be struggling.
Lavender can become woody and sparse over time, especially without proper pruning, losing its vibrant shape and abundant blooms. You might also be re-designing your garden, making way for different plants that thrive better in your specific conditions, or simply craving a change.
When Lavender Outgrows Its Welcome
Mature lavender plants can develop extensive root systems and a robust woody structure. What started as a charming small shrub can, within a few years, become a substantial presence.
This growth can compete for nutrients and water with nearby plants, leading to a less harmonious garden bed. Sometimes, simply pruning isn’t enough to restore the desired aesthetic or control its size.
Recognizing when a plant has truly outgrown its space is the first step towards a more balanced and beautiful garden.
Preparing for Lavender Removal: Tools and Safety
Like any gardening task, preparation is key. Having the right tools on hand will make the job much smoother and more efficient. Safety is also paramount, especially when dealing with established plants.
Gather your equipment before you begin. This will save you time and frustration during the removal process.
Essential Tools for the Task
You don’t need a professional landscaper’s arsenal, but a few key items will be invaluable:
- Sturdy Gardening Gloves: Protect your hands from thorns, rough branches, and potential skin irritants.
- Sharp Pruning Shears or Loppers: For cutting back the top growth of the plant. Loppers are great for thicker, woody stems.
- Garden Fork or Spade: A robust tool for loosening soil and prying out roots. A garden fork is often better for aerating and getting under roots without severing them too easily.
- Wheelbarrow or Tarp: To collect the removed plant material.
- Watering Can or Hose: To moisten the soil, making it easier to dig.
- Hori Hori Knife (Optional): A versatile Japanese gardening tool that’s excellent for digging, cutting roots, and weeding.
Safety First!
Always prioritize your safety. Wear appropriate clothing, including long sleeves and pants, especially if you have sensitive skin. While lavender isn’t generally known for causing severe skin irritation, some individuals can be sensitive to plant oils.
Use proper lifting techniques to avoid back strain. If the plant is very large, consider breaking the task into stages or enlisting a helper.
How to Get Rid of Lavender Plants: A Step-by-Step Approach
Now, let’s get down to the practical steps for removing your lavender. This method focuses on manual removal, which is generally the most environmentally friendly and effective for most home gardens.
Taking your time with each step will ensure a thorough job, preventing regrowth and preparing your garden bed for its next inhabitant.
Step 1: Prune Back the Top Growth
The first step is to reduce the plant’s bulk. This makes it much easier to access the base and root system. Use your pruning shears or loppers to cut back all the woody stems.
Aim to cut the branches back to about 6-12 inches from the ground, leaving a manageable stump. This will give you clear access to the soil around the base.
Don’t worry about being too tidy at this stage; the goal is simply to remove the foliage mass. Collect the pruned material in your wheelbarrow or on a tarp for easy disposal or composting.
Step 2: Hydrate the Soil
Dry, compacted soil makes digging incredibly difficult. About an hour before you plan to remove the plant, thoroughly water the area around the base of the lavender.
Allow the water to soak in deeply. Moist soil is much looser and more forgiving, allowing your spade or fork to penetrate easily and making it simpler to extract the root ball without excessive force.
This is a small but mighty “pro” tip that can save you a lot of effort!
Step 3: Digging Out the Root Ball
This is the main event. Start by digging a trench around the perimeter of the remaining lavender stump. Aim for a circle that is roughly the same diameter as the plant’s former canopy, or slightly wider.
Dig deeply, at least 12-18 inches, depending on the plant’s age and size. Lavender has a fibrous root system that can extend surprisingly far. Use your garden fork or spade to gently loosen the soil around the root ball.
Work your way around the plant, prying the soil up and under the roots. Be patient and persistent. You’ll likely encounter some resistance from deeper taproots or lateral roots.
Step 4: Levering Out the Plant
Once you’ve loosened the soil all around, try to lever the plant out of the ground. You can use your spade or fork as a lever, pushing down on the handle while lifting the root ball.
If the plant is stubborn, you might need to dig a bit deeper or widen your trench. Don’t be afraid to rock the plant back and forth to break any remaining root anchors. The goal is to remove as much of the main root system as possible.
Smaller root fragments left behind are less likely to regrow vigorously, but larger sections can sprout new growth. Inspect the hole for any significant remaining root pieces and remove them manually.
Step 5: Inspect and Clear the Area
After removing the main plant, take a moment to inspect the area. Look for any substantial root fragments left in the soil. These can potentially regrow if not removed, especially if they are attached to viable woody pieces.
Use a smaller hand trowel or your hori hori knife to meticulously clear out any remaining root debris. The cleaner the bed, the less likely you’ll have surprise lavender sprouts later on.
This thorough clearing ensures that your efforts to how to get rid of lavender plants are truly successful.
Dealing with Stubborn Lavender: Advanced Techniques
Sometimes, a particularly established or neglected lavender plant might prove more challenging. If manual digging isn’t quite cutting it, or you’re dealing with a very large area, consider these advanced strategies.
These methods require a bit more patience but can be highly effective for persistent plants or larger patches.
Solarization for Extensive Patches
If you have a large bed of lavender you wish to remove, or if you’re battling persistent regrowth, solarization can be an excellent non-chemical option. This method uses the sun’s heat to “cook” the soil, killing plants, seeds, and even some pathogens.
- Clear the Area: First, cut down the lavender plants as close to the ground as possible.
- Water Thoroughly: Water the soil deeply to promote heat transfer.
- Cover with Plastic: Lay clear plastic sheeting (4-6 mil thick) over the entire area, extending beyond the lavender patch by at least a foot.
- Seal the Edges: Bury the edges of the plastic with soil, rocks, or bricks to create an airtight seal. This traps heat and moisture.
- Wait: Leave the plastic in place for 4-8 weeks during the hottest, sunniest part of the year. The sun will heat the soil to temperatures lethal to plant life.
This method is highly effective but does take time, making the area unusable for planting during the solarization period.
Repeated Cutting and Depletion
For smaller, but very persistent plants, a strategy of repeated cutting can work. This method aims to deplete the plant’s energy reserves over time.
Every time you see new shoots emerge, cut them back immediately to the ground. Do not let them develop leaves and photosynthesize. Without the ability to create food, the roots will eventually starve and die.
This requires vigilance and can take several months, but it’s a good option if you want to avoid digging or chemicals.
When to Consider Chemical Assistance (Use with Caution!)
For most home gardeners, manual removal is sufficient and preferred. However, in cases of extremely large, deeply rooted, or invasive lavender where other methods have failed, you might consider a targeted herbicide application.
This should always be a last resort. If you choose this route, select a non-selective herbicide containing glyphosate. Apply it directly to freshly cut stumps of the lavender, rather than spraying the entire plant. This minimizes drift and impacts on surrounding vegetation.
Always read and follow the manufacturer’s instructions carefully. Wear protective gear, and be aware of any restrictions regarding nearby water sources or edible plants. Allow several weeks for the chemical to work before attempting to remove the dead plant material.
Post-Removal Care and What to Plant Next
Once you’ve successfully removed your lavender, the area is ripe for new possibilities! But before you plant, a little post-removal care will ensure your soil is healthy and ready for its next resident.
This is your chance to amend the soil and create ideal conditions for whatever you choose to grow next.
Soil Amendment and Preparation
After removing the lavender, the soil might be compacted or depleted. Take this opportunity to improve its structure and fertility:
- Loosen the Soil: Use your garden fork to loosen the soil in the entire planting area to a depth of at least 12 inches. This improves drainage and aeration.
- Add Organic Matter: Incorporate a generous amount of compost, well-rotted manure, or other organic matter. This enriches the soil, improves its texture, and provides nutrients.
- Test Soil pH (Optional but Recommended): Lavender prefers alkaline to neutral soil. If you’re planting something with different pH requirements, a soil test will tell you if you need to adjust the pH.
Mixing in organic matter is crucial for creating a healthy environment for new plants. It helps break down any remaining tiny root fragments and revitalizes the soil biome.
Choosing Your Next Garden Star
Now for the fun part! With your garden bed clear, you have a blank canvas. Consider what you want to achieve with the space:
- Consider Sunlight and Drainage: Evaluate the light conditions and how well the soil drains. Lavender thrives in full sun and well-drained soil, so if you’re replacing it, these conditions likely exist.
- Match Plant Needs: Choose plants that will thrive in these conditions. If you loved the aromatic qualities, consider herbs like rosemary, thyme, or sage.
- Diverse Planting: Think about varying heights, textures, and bloom times to create year-round interest. Ornamental grasses, coneflowers, sedums, or even small shrubs could be excellent choices.
This is a wonderful opportunity to introduce new colors, forms, and fragrances to your garden, enhancing its overall appeal.
When to Call in the Pros
While removing lavender is a manageable DIY task for most gardeners, there are instances where calling in professional help is wise. Knowing your limits can save you time, effort, and potential injury.
Don’t hesitate to seek expert assistance if the job feels overwhelming.
Large Scale Removals or Difficult Terrain
If you’re dealing with an entire hedge of mature lavender, or if the plants are located on a steep slope or in extremely rocky, compacted soil, a professional landscaper or garden service might be your best bet.
They have the heavy-duty equipment, experience, and workforce to handle large-scale removals efficiently and safely. This is especially true if you need to remove a significant amount of earth or roots.
Unsure About Chemical Use
If you feel that chemical intervention is necessary but are uncomfortable or unsure about proper application, always consult a professional. They can apply herbicides safely and effectively, minimizing environmental impact.
A certified arborist or landscape professional can assess the situation and recommend the most appropriate and safest method for your specific needs.
Frequently Asked Questions About Removing Lavender
Will lavender regrow if I just cut it back?
Yes, if you only cut back the top growth and leave the root system intact, lavender will almost certainly regrow. To truly get rid of it, you need to remove as much of the root ball as possible.
Can I compost removed lavender plants?
Yes, you can compost the pruned foliage and even the smaller root pieces. However, avoid adding large, woody stems or any parts that show signs of disease to your compost pile, as they break down slowly and could spread pathogens.
What time of year is best to remove lavender?
The best time to remove lavender is during the dormant season (late fall or early spring) when the plant’s energy reserves are lowest, or when the soil is moist but not waterlogged. This makes digging easier and reduces stress on surrounding plants if you’re trying to save them.
How deep do lavender roots go?
Lavender roots can extend surprisingly deep, often 12-18 inches or more, especially in well-drained soil. They also spread laterally, forming a robust, fibrous root ball. This is why thorough digging is essential for complete removal.
Is lavender considered an invasive plant?
Generally, no. Common garden lavender (Lavandula angustifolia and its hybrids) is not considered invasive in most regions. It spreads by seed and can self-sow, but it doesn’t typically aggressively outcompete native plants or take over wild areas like true invasive species. However, it can certainly spread beyond its intended bounds in a garden bed.
Conclusion
Removing a well-established lavender plant might seem like a big job, but with the right tools, a clear plan, and a bit of elbow grease, it’s a perfectly achievable gardening task. Remember, gardening is all about evolution and adapting your space to your vision.
By following these steps, you can confidently clear your garden beds, ensuring that your efforts to how to get rid of lavender plants are successful and your soil is ready for new growth. This process isn’t just about removal; it’s about renewal and creating opportunities for your garden to flourish in exciting new ways.
So, gather your tools, roll up your sleeves, and get ready to transform your garden space. Happy gardening!
