Why Grow Two Lavender Plants in One Pot?
You might be wondering, “Why bother with two plants when one seems simpler?” The answer lies in the incredible benefits this technique offers. It’s not just a clever trick; it’s a strategic way to enhance your gardening experience.
Firstly, planting two lavender plants in a single, appropriately sized container immediately creates a much fuller, more voluminous appearance. Instead of a single, sometimes sparse, plant, you get a dense mound of foliage and flowers that truly makes an impact.
This density also amplifies the renowned lavender fragrance. With twice the blooms, your patio, entryway, or window box will be enveloped in an even richer, more intoxicating aroma. It’s an instant mood booster and a natural insect deterrent.
Furthermore, this method can be a smart space-saving solution. If you have limited outdoor area but want a significant lavender presence, consolidating two plants into one larger pot allows for a grander display without occupying extra footprint.
Choosing the Right Pot and Lavender Varieties
Success starts with the right foundation. Selecting the perfect container and compatible lavender varieties are crucial steps when planning to house multiple plants.
Container Size and Material Considerations
When you decide to place two lavender plants in one pot, size truly matters. Lavender, especially when sharing space, needs ample room for its root system to spread without competing excessively for nutrients and moisture.
- Size: For two standard lavender plants (like English or French varieties), aim for a pot that is at least 18-24 inches in diameter and 12-16 inches deep. Larger varieties like ‘Grosso’ might even need something closer to 24-30 inches across.
- Drainage: This is non-negotiable! Lavender hates wet feet. Ensure your chosen pot has multiple, generous drainage holes at the bottom. You can even add a layer of gravel or broken terracotta shards before adding soil, but the most important thing is excellent drainage from the holes themselves.
- Material: Terracotta pots are often recommended for lavender because their porous nature allows for better air circulation around the roots and helps the soil dry out more quickly, which lavender prefers. Plastic or glazed ceramic pots can work, but they retain moisture longer, so adjust your watering schedule accordingly.
- Weight: Consider the final weight. A large terracotta pot filled with soil and two mature lavender plants can be very heavy. If you plan to move it, choose a lighter material or a pot with wheels.
Selecting Complementary Lavender Varieties
Not all lavenders are created equal, and choosing the right types to grow together will ensure both thrive. Think about their growth habits, mature size, and environmental needs.
- English Lavender (Lavandula angustifolia): These are generally compact, hardy, and have a wonderfully sweet fragrance. Varieties like ‘Munstead’ and ‘Hidcote’ are excellent choices for pots due to their manageable size and robust nature. They are also very cold-hardy.
- French Lavender (Lavandula stoechas): Known for its distinctive “bunny ear” bracts, French lavender prefers slightly warmer climates and is less cold-hardy than English varieties. It tends to be a bit bushier. If combining, ensure both chosen varieties have similar light and watering needs.
- Lavandin (Lavandula x intermedia): These are hybrids, often larger and more vigorous, with long flower spikes. Varieties like ‘Grosso’ or ‘Provence’ are popular for their strong fragrance and oil production. If you choose these, you’ll need a very large pot, as they can grow quite substantial.
For the best results when growing two lavender plants in one pot, I recommend sticking to two plants of the same variety or varieties with very similar growth rates and care requirements. This prevents one plant from outcompeting the other for resources and ensures a uniform, beautiful display.
Preparing Your Potting Mix for Success
The right soil is paramount for lavender. These plants hail from Mediterranean climates, meaning they thrive in lean, well-draining conditions. Replicating this in a pot is key.
The Ideal Soil Blend for Potted Lavender
Forget heavy garden soil. Lavender needs a specialized mix that drains quickly and prevents root rot. This is especially true when you have two lavender plants in one pot, as moisture management becomes even more critical.
- Base Potting Mix: Start with a high-quality, lightweight potting mix designed for containers. Avoid mixes that are heavy in peat moss, as they can retain too much moisture.
- Perlite or Pumice: Amend your potting mix generously with perlite or pumice. Aim for a ratio of about 1 part perlite/pumice to 2-3 parts potting mix. This dramatically improves drainage and aeration, which lavender roots adore.
- Coarse Sand or Grit: Adding some coarse horticultural sand or fine gravel can further enhance drainage. Avoid play sand, as it can compact.
- pH Level: Lavender prefers slightly alkaline to neutral soil (pH 6.5-7.5). If your potting mix is on the acidic side, you can add a small amount of horticultural lime to adjust the pH. A soil test kit can confirm this.
A good rule of thumb: when you water, the excess should drain out almost immediately. If water sits on the surface or drains slowly, your mix isn’t porous enough.
The Art of Planting: Spacing and Depth
Proper planting technique ensures your lavender plants get the best possible start and have room to flourish. This is where attention to detail pays off, particularly when arranging two plants.
Step-by-Step Planting Guide
Follow these steps carefully to give your lavender the best chance at a thriving partnership in its new home.
- Prepare the Pot: Ensure your large pot has excellent drainage holes. Place a screen or a few broken pot shards over the holes to prevent soil from washing out while still allowing water to escape freely.
- Add Drainage Layer (Optional but Recommended): A 1-2 inch layer of coarse gravel or pumice at the bottom can further aid drainage, especially in very deep pots.
- Fill with Soil: Fill the pot about one-third to halfway with your custom-blended potting mix. Create two small mounds of soil where each plant will sit.
- Remove Plants from Nursery Pots: Gently remove each lavender plant from its nursery container. If the roots are tightly bound (root-bound), carefully tease them apart with your fingers to encourage outward growth.
- Position the Plants: Place one plant on each soil mound. Position them slightly off-center towards opposite sides of the pot, leaving a generous space in the middle. The goal is to give them enough breathing room so their mature foliage won’t be constantly touching or overlapping too much, which can hinder air circulation.
- Check Depth: The top of the root ball should be level with, or slightly below, the rim of the pot once filled, but not covered by new soil. Lavender doesn’t like its crown buried.
- Backfill with Soil: Carefully fill the rest of the pot with your potting mix, gently firming it around the root balls. Leave about 1-2 inches of space between the soil surface and the rim of the pot for watering.
- Water Thoroughly: Water your newly planted lavenders deeply until water drains freely from the bottom. This helps settle the soil and eliminates air pockets.
Remember, proper spacing is crucial. While you want a full look, overcrowding can lead to poor air circulation, making your plants susceptible to fungal diseases. Aim for about 6-8 inches between the base of the two plants in an 18-24 inch pot.
Essential Care for Potted Lavender: Watering, Light, and Pruning
Once your two lavender plants are settled in one pot, consistent care is key to their long-term health and abundant blooms. Lavender is relatively low-maintenance, but container-grown plants have specific needs.
Watering Wisdom for Container Lavender
This is arguably the most critical aspect of lavender care. Overwatering is the quickest way to kill a lavender plant.
- Frequency: Allow the soil to dry out completely between waterings. Stick your finger about 2 inches deep into the soil; if it feels dry, it’s time to water. In hot, sunny weather, this might be every few days. In cooler, cloudy periods, it could be once a week or less.
- Technique: When you do water, water deeply until you see water flowing out of the drainage holes. This encourages deep root growth. Avoid frequent, shallow watering.
- Seasonal Adjustment: Reduce watering significantly in the fall and winter, especially if your plants are exposed to cold temperatures. Dormant lavender needs very little moisture.
Monitoring the soil moisture is vital, especially since two plants will draw more water than one, but still hate being waterlogged.
Light Requirements for Abundant Blooms
Lavender is a sun-worshipper. It needs as much direct sunlight as possible to produce those beautiful, fragrant flowers.
- Full Sun: Aim for at least 6-8 hours of direct sunlight per day. More is always better for lavender.
- Location: Place your pot in the sunniest spot on your patio, deck, or garden. A south-facing location is often ideal.
- Rotation: If one side of your pot consistently gets more sun, consider rotating the pot every week or so to ensure both plants receive even light exposure.
Insufficient light will result in leggy growth, fewer flowers, and a weaker fragrance.
The Art of Pruning for Shape and Vigor
Pruning is essential for maintaining a compact, bushy shape and encouraging prolific blooming. It prevents your lavender from becoming woody and leggy.
- First Year: In the first year, focus on shaping. After the first flush of blooms, snip off the spent flower stalks. You can also lightly trim the foliage to encourage branching.
- Annual Pruning (Early Spring/After Flowering): The main pruning happens either in early spring (after the last frost but before new growth fully emerges) or immediately after the main flush of summer blooms. Cut back about one-third of the plant’s growth, shaping it into a neat mound. Avoid cutting into the old, woody stems, as lavender doesn’t readily sprout from old wood.
- Deadheading: Regularly snip off spent flower stalks throughout the blooming season. This encourages the plant to produce more flowers rather than putting energy into seed production.
Pruning not only keeps your plants looking tidy but also improves air circulation, which is beneficial when you have two lavender plants in one pot.
Troubleshooting Common Issues with Container Lavender
Even with the best intentions, gardeners sometimes face challenges. Knowing how to identify and address common problems can save your beloved lavender.
Dealing with Yellowing Leaves and Leggy Growth
These symptoms often point to environmental stressors or improper care.
-
Yellowing Leaves:
- Overwatering: This is the most common culprit. If leaves are yellow and soft, or the plant looks generally droopy, check the soil moisture. Let the pot dry out thoroughly before the next watering.
- Nutrient Deficiency: While lavender prefers lean soil, prolonged nutrient deprivation can cause yellowing. A very light application of a balanced, slow-release granular fertilizer (low in nitrogen) in early spring can help.
- Poor Drainage: Ensure your pot’s drainage holes aren’t blocked.
-
Leggy Growth:
- Insufficient Light: Lavender stretches towards the sun when it’s not getting enough. Move your pot to a sunnier location.
- Lack of Pruning: Regular pruning prevents legginess. If your plant is already leggy, a good pruning session (cutting back about a third of the green growth) can help rejuvenate it.
Pest and Disease Management
Lavender is generally pest-resistant due to its strong essential oils, but container plants can still encounter issues.
-
Pests:
- Aphids and Whiteflies: These can occasionally appear on new growth. A strong spray of water can dislodge them, or use an insecticidal soap if the infestation is severe.
- Spider Mites: More common in hot, dry conditions. Look for fine webbing. Increase humidity around the plant and use insecticidal soap.
-
Diseases:
- Root Rot: Caused by overwatering and poor drainage. Symptoms include wilting, yellowing, and eventually plant death. Prevention is key: excellent drainage and proper watering. If caught early, repotting into fresh, dry soil and pruning affected roots might save the plant.
- Fungal Issues (e.g., powdery mildew): Less common for lavender but can occur in humid conditions with poor air circulation. Ensure good spacing between your two plants and adequate airflow.
Regular inspection is your best defense. Catching problems early makes them much easier to resolve.
Maximizing Fragrance and Bloom Production
Beyond basic care, there are a few “pro” tips to ensure your two lavender plants in one pot deliver their absolute best in terms of scent and floral abundance.
Strategic Fertilization and Soil Amendments
Lavender is not a heavy feeder, but a little strategic nourishment can go a long way.
- Less is More: Avoid high-nitrogen fertilizers, which promote leafy growth at the expense of flowers.
- Balanced, Slow-Release: In early spring, apply a very light dose of a balanced, slow-release granular fertilizer (e.g., 5-10-5 or 10-10-10). This provides a gentle boost without overfeeding.
- Organic Matter: While lavender likes lean soil, a thin layer of compost (about half an inch) applied to the soil surface in spring can slowly release nutrients and improve soil structure without making it too rich.
- Epsom Salts: Some gardeners find that a diluted solution of Epsom salts (magnesium sulfate) can enhance blooming and foliage color. Use sparingly, perhaps once a season.
Harvesting for Peak Potency and Encouraging Rebloom
Harvesting lavender isn’t just for crafting; it’s also a form of pruning that encourages more blooms.
- When to Harvest: The best time to harvest lavender for its fragrance and essential oils is when about half of the flower buds on a spike have opened. This is when the oils are most concentrated.
- How to Harvest: Use sharp, clean pruners or scissors. Cut the flower stalks just above the first set of leaves on the stem. This encourages the plant to produce side shoots and, often, another flush of blooms.
- Encouraging Rebloom: Regular deadheading (removing spent flowers) throughout the season is crucial. If you don’t harvest for crafts, simply snip off the faded blooms. Many lavender varieties, especially English types, will offer a second, smaller flush of flowers if deadheaded promptly.
Remember, happy, well-pruned plants are productive plants. By giving your two lavender plants in one pot this attentive care, you’ll be rewarded with an unparalleled sensory experience.
Frequently Asked Questions About Growing Potted Lavender
How often should I repot my two lavender plants in one pot?
Lavender generally prefers to be slightly root-bound, but eventually, even two plants in a large pot will outgrow their space. Plan to check their root system every 1-2 years. If roots are circling heavily or growing out of the drainage holes, it’s time to either repot into an even larger container (if possible) or divide the plants into separate pots.
Can I use regular garden soil for potted lavender?
No, absolutely not. Regular garden soil is too heavy and retains too much moisture for lavender, especially in a pot. It compacts easily, preventing proper drainage and air circulation, which can quickly lead to root rot. Always use a well-draining, sandy potting mix amended with perlite or pumice.
What if one of my lavender plants starts to die?
If one plant shows signs of decline (e.g., severe wilting, yellowing, or browning), first check for overwatering or poor drainage. If the issue persists and the plant appears unsalvageable, it’s best to remove it to prevent any potential disease from spreading to the healthy plant. You can then gently loosen the soil around the remaining plant and potentially add fresh soil, or consider replacing the deceased plant with a new one after assessing the cause of death.
Do I need to fertilize my container lavender?
Lavender is not a heavy feeder. In fact, too much fertilizer, especially high-nitrogen types, can lead to lush foliage but fewer flowers. A light application of a balanced, slow-release granular fertilizer in early spring is usually sufficient. Focus more on providing excellent drainage, ample sunlight, and proper pruning.
Can I bring my potted lavender indoors for winter?
While some people try, lavender generally struggles indoors due to insufficient light and often too-warm, dry air. If you live in a region with harsh winters (below USDA Zone 5), it’s better to provide winter protection outdoors (e.g., wrapping the pot in burlap, moving it to a sheltered location) or choosing cold-hardy varieties. If you must bring it indoors, place it in the coolest, brightest spot possible, away from heating vents, and reduce watering significantly.
Conclusion
Growing two lavender plants in one pot is a truly rewarding endeavor, offering a double dose of beauty and fragrance that can transform any space. From the initial excitement of choosing your perfect pot and varieties to the satisfying routine of expert care, you’re not just growing plants—you’re cultivating a sensory experience.
Remember the golden rules: excellent drainage, abundant sunshine, and thoughtful pruning. By providing these essentials, your dual lavender display will flourish, filling your garden with its calming aroma and vibrant purple hues.
So, take a deep breath, embrace the simple elegance of lavender, and get ready to enjoy a magnificent, fragrant spectacle. Your gardening journey is about to become even more delightful. Happy planting!
