You can grow rosemary and lavender in the same pot, but it takes a bit of planning to make them thrive together.
Both of these Mediterranean herbs share a love for sunshine, well-draining soil, and drier conditions, which is a fantastic starting point.
However, growing rosemary and lavender in the same pot isn’t as simple as just tossing them in any container and hoping for the best.
Before you start combining rosemary and lavender in the same pot, you need to think about pot size, soil mix, watering routines, and the individual growth habits of each plant.
In this post, we’ll look at why you can grow rosemary and lavender in the same pot, the best way to set up that shared container, and what mistakes to avoid so both herbs stay healthy.
Why Rosemary And Lavender Can Grow In The Same Pot
The short answer is yes, rosemary and lavender can grow in the same pot because they have nearly identical cultural requirements.
Both of them are native to rocky, sunny, and dry parts of the Mediterranean, so they’ve evolved to survive in poor, sandy soil with very little water.
When you’re wondering if you can grow rosemary and lavender in the same pot, the key is matching their needs for light and drainage.
1. They Both Crave Full Sun
Rosemary and lavender are sun worshippers that need at least six to eight hours of direct sunlight every day.
If you place a pot with rosemary and lavender in a shady spot, both herbs will become leggy, weak, and more prone to fungal diseases.
So yes, you can grow rosemary and lavender in the same pot, but only if that pot sits in the brightest location you can find.
2. They Both Hate Wet Feet
Root rot is the number one killer of both rosemary and lavender, and that’s why drainage is non-negotiable.
When you plant rosemary and lavender in the same pot, the soil must dry out almost completely between waterings.
These plants prefer a gritty, sandy, or even rocky potting mix that mimics their homeland instead of a rich, moisture-retentive one.
3. They Share Similar Soil Preferences
Rosemary and lavender both love a slightly alkaline to neutral soil with a pH between 6.5 and 7.5.
This shared preference means you don’t have to make two different soil recipes for each plant.
Growing rosemary and lavender in the same pot actually simplifies your life because one bag of cactus or succulent mix with added perlite works perfectly for both.
4. They Have Matching Drought Tolerance
Both herbs are remarkably drought-tolerant once established, which means they won’t fight over water in a shared container.
Since you can grow rosemary and lavender in the same pot without one hogging all the moisture, you’ll water them on the same schedule.
Choosing The Right Pot For Rosemary And Lavender
If you want to successfully grow rosemary and lavender in the same pot, choosing the correct container is the most critical decision you’ll make.
Forget those cute little decorative pots because they simply don’t provide enough room for root growth.
1. Go Big With The Container Size
Rosemary develops a deep, extensive root system, while lavender sends out a wide, woody root network of its own.
When you grow rosemary and lavender in the same pot, you’ll need a container that’s at least 18 to 24 inches in diameter and equally deep.
A pot this size gives each herb enough space to spread out without choking the other.
2. Ensure Plenty Of Drainage Holes
A pot without drainage holes is a death sentence for both rosemary and lavender.
Look for a container with multiple holes at the bottom and consider raising it on pot feet so excess water flows away freely.
Growing rosemary and lavender in the same pot requires that you never allow water to pool around the roots.
3. Choose The Right Material
Terracotta pots are an excellent choice when you want to grow rosemary and lavender in the same pot because they’re porous.
This porous nature allows excess moisture to evaporate through the walls, which helps the soil dry out faster.
Plastic pots hold too much moisture and increase the risk of root rot, so if you have to use plastic, be extra careful with watering.
Planting Rosemary And Lavender Together Step By Step
Now that you know you can grow rosemary and lavender in the same pot, here’s exactly how to set them up for success.
1. Start With A Well-Draining Soil Mix
When you plant rosemary and lavender in the same pot, skip regular garden soil and use a mix of two parts potting soil, one part coarse sand, and one part perlite.
This creates the sharp drainage both herbs need to prevent their roots from sitting in moisture.
2. Space Them Properly Inside The Pot
Remember that rosemary can grow into a large shrub, so give it a bit more room than lavender.
Place rosemary on one side where it has room to expand, and tuck lavender on the other side slightly toward the front.
You can successfully grow rosemary and lavender in the same pot, but only if you leave at least six to eight inches between them.
3. Water Less Frequently Than You Think
After planting, water deeply once and then let the top two inches of soil dry out before watering again.
A great trick is to stick your finger into the soil, and if it feels dry, then water, and if it feels damp, wait another day.
When you grow rosemary and lavender in the same pot, underwatering is far better than overwatering.
Common Mistakes When Growing Rosemary And Lavender Together
Even though you can grow rosemary and lavender in the same pot, there are some pitfalls that will kill both plants quickly.
1. Overwatering Is The Biggest Problem
The most common mistake with rosemary and lavender in the same pot is loving them too much with water.
These herbs are not like your thirsty annuals that need daily drinks, so resist the urge to water on a fixed schedule.
2. Using Rich Soil Or Compost
Fertile, rich soil that’s packed with compost can actually harm rosemary and lavender growth.
You see, these herbs are adapted to lean conditions, so too many nutrients cause floppy growth and diminished essential oils.
Growing rosemary and lavender in the same pot is best done with a poor, lean mix rather than a rich one.
3. Not Pruning Either Plant Regularly
Both rosemary and lavender need regular pruning to stay compact and avoid becoming woody at the base.
When you grow rosemary and lavender in the same pot, prune them lightly in spring and after flowering to keep them healthy.
4. Bringing Them Inside During Winter
If you keep rosemary and lavender in a pot outdoors, don’t move them into a warm, stuffy house for winter.
They actually need a cool, bright, and dormant period to rest, so an unheated garage or a sheltered porch is a much better choice.
So, Can You Grow Rosemary And Lavender In The Same Pot?
Yes, you can grow rosemary and lavender in the same pot as long as you respect their love for sun, sharp drainage, and infrequent water.
These two herbs make wonderful companions when you give them a big terracotta container and a sandy soil mix.
Growing rosemary and lavender in the same pot is a smart way to save space and create a beautiful aromatic display on your patio or balcony.
Just remember to keep that pot in full sun, water deeply but rarely, and never let the soil stay soggy.
With those simple rules, you’ll enjoy healthy, fragrant rosemary and lavender in the same pot for years to come.
