Choosing a Lavender for Pots and Containers
All lavender plants grow well in pots and containers due to the favorable drainage conditions, however there are some lavender cultivars that are most suited to growing in pots then others.
My personal favorite lavender that I recommend for growing in pots are the English lavenders (Lavandula angustifolia):
- ‘Hidcote’
- ‘Munstead’
Both of these lavenders are English lavenders which means the can tolerate colder weather (cold hardy to USDA zone 5) and therefore the pot can be left outdoors all year.
Hidcote and Munstead lavender also have the finest fragrance of all the lavenders and display beautiful flowers in the middle of Summer.
They also stay a relatively compact size of around 12 inches (with annual pruning) therefore grow to a size that works great in pots without having to repot them too often as can happen with the larger varieties of lavender (such as ‘Vera’) which can grow 3 feet across and is therefore more suited to growing in garden boarders
Other great choices for pots are most varieties of French and Spanish lavenders with popular varieties such as:
- ‘Bandera pink‘
- ‘Anouk’
These lavenders stay a good size that do not overwhelm a pot and produce flowers for up to 3 months in the right conditions. The fragrance however is less pronounced then the English lavender varieties.
It should be noted that they are not as cold hardy as English lavenders and the pots should be taken indoors for Winter protection as they can die in a heavy frost.
English lavender also can live for up to 15 years or more with good care whereas French Lavenders often die after 5 years even with optimal conditions.

Best Pots and Containers for Growing Lavender
The best pots for growing lavender are ceramic, clay or terracotta pots as they do not conduct as much heat as plastic and metal pots and tend to be a bit thicker which helps to resist frost damage in Winter. Ceramic, clay and terracotta are also porous which dries the soil evenly to avoid root rot.
Lavenders are Mediterranean herbs that grow in gritty, well draining soils and require the soil to dry out between bouts of watering.
The clay, ceramic and terracotta pots are able to dry the soil more evenly thanks to their more porous stricture yet also do not heat up as quickly in full sun. They can also protect the lavender’s cold sensitive roots more in colder weather which is important as many lavender varieties do not tolerate freezing temperatures.
Choose a pot or container for your lavender that is around 12 inches across with the same proportional depth.
A pot this size has the capacity for enough soil which acts as insulation from frost for the cold sensitive roots and also allows the roots enough room to develop properly to access nutrients and moisture.
Always ensure the pot or container has drainage holes in the base to allow excess water to escape after watering to prevent root rot.
If your potted lavender is on a patio then I recommend placing the pot on feet to elevate an inch or so off the ground, which ensures water can escape freely from the bottom of the pot without pooling underneath.
Note lavender should be grown in full sun and if they pot is significantly smaller then 12 inches across then a smaller pot with less soil is going to heat up and dry out too quickly for even the drought tolerant lavender’s roots to draw up any moisture.
(Read my article, choosing the best pot for lavender, for examples).
How To Water Lavender in Pots
Water lavender with a really generous soak, so that excess water trickles from the drainage holes and out the base of the pot. This encourages the roots to grow deeper into the soil to access the moisture which increases the lavenders resistance to drought.
If you water lavender too lightly then only the top inch or so of the potting soil becomes moist which causes the roots to grow near the surface and can increase lavenders vulnerability to drought stress.
Water with a good soak so that water emerges from the holes in the base of the pot ensures the soil is evenly moist so that the roots can access the moisture they require.
Always water the at the soil level rather then overhead watering. If you water overhead this can create a humid micro-climate around the foliage which increase the risk of fungal disease which turns the foliage gray.
How Often to Water Lavender in Pots
Water established lavenders in pots and containers every 2 weeks in the Spring and Summer with a thorough watering. Established potted lavender does not need any additional watering in Fall and Winter. Water newly planted potted lavenders every week for the first year after planting.
| Lavender in Pots and Containers: | How Often to Water Potted Lavender: |
| Newly Planted Lavenders: | Water once per week during Spring and Summer. Do not water in Fall or Winter. |
| Established Lavenders: | Once every 2 weeks in Spring and Summer if there has been no significant rainfall. |
| Potted Lavender in Fall and Winter: | Lavender rarely requires watering in Winter as root rot is more of a risk. Lavender typically attains all the moisture it require form the environment in Fall and Winter. |
Lavenders are drought resistant herbs that have adapted to the hot and dry Mediterranean region of Europe. Therefore they do not require watering as often as most potted plants as they actually thrive in the hottest, direst months of the year.
Watering with a really good soak and then allowing the soil to dry out over 2 weeks replicates the typical cycle of rainfall followed by a period of drought that lavenders typically experience in their native environment.
If there has been significant rainfall or many overcast days then delay watering until the soil has dried.
Lavenders (as with all Mediterranean herbs) are very sensitive to overwatering, so If you water potted lavender too frequently then this promotes the conditions for root rot which turns the lavender brown, causes it to wilt and die back.
Therefore if in doubt about whether to water your potted lavender, delay watering for a few days until you are sure the soil has had a chance to dry out.
(Read my article, how often to water lavender for the complete guide).
Watering Newly Planted Lavenders
The only time lavender is vulnerable to drought is when it is newly planted as the roots need some time to establish and uptake moisture more effectively.
The best time to plant lavenders in pots is in the Spring as the lavender has some time for their roots to establish before the more intense Summer sun and heat, however they can be successfully be planted at anytime during the Spring and Summer.
Water newly planted lavenders with a really good soak once per week throughout Spring and Summer up and into Fall. Watering newly planted lavenders with a good soak once per week promotes the lavenders roots to develop to keep so it can become more resistant to drought as it matures.
It is worth emphasizing the importance of planting in lavender in pots that measure 12 inches across and preferably a clay, ceramic or terracotta pot as smaller pots can dry out too quickly for a newly planted lavender and the clay, ceramic or terracotta materials dry out evenly due to their porous structure which helps to achieve the optimal balance of moisture for potted lavenders to thrive.
If planting lavender in pots in Summer water more frequently in intense sunlight and high temperature and ideally find some begins to droop.
Potting Soil for Lavenders in Pots and Containers
The best potting soil for lavenders is a mix of 70% compost to 30% horticultural sand or grit. This balance of compost and sand, replicates the gritty soil conditions of the lavenders native environment and porous, light, aerated soil structure that allows for good drainage and efficient root respiration.
Lavenders are native to countries such as Spain, France and Italy where they grow in soils with a high inorganic content with lot of grit and organic matter.
The most important characteristic of lavender potting soil is to allow for good drainage around the lavenders roots as damp soil promotes the conditions for fungal disease pathogens such as root rot which is the most common reason for lavender dying.
Pots naturally have more favorable drainage conditions then the soil in garden boarders, so they are a great way to grow lavenders, but in climates of higher rainfall or higher humidity the faster the drainage the better.
This means as much as 50% compost and 50% horticultural sand or mix may be necessary to counteract the affects of more rainfall which can cause the soil to be too damp for lavender to tolerate. Simply mix the compost and the sand in the pot together until it is evenly distributed.
Watch the video I created which shows how to create the perfect potting mix for lavenders:
Too much grit is always better then not enough so be generous when creating your lavender potting soil mix.
Lavenders also require medium to low fertility soil as nutrient dense soils cause lavenders to grow lots of foliage without any flowers.
Too much nutrients (particularly nitrogen) also decreases the concentration of essential oils in the leaves which reduces the strength of the lavenders distinctive aroma.
Lavender have specifically adapted to growing in poor soils and actually thrive in these conditions.
The sand or horticultural grit in the potting mix, do not contribute much nutrients to the soil which balances out the compost to recreate the lower fertility soil conditions of the lavenders native environment where they thrive.
(Read my article, how to revive a dying lavender plant).
Locate Potted Lavender in 6 hours of Sun
Position your potted lavender in an area with full sun. Lavenders has specifically adapted to growing in 6 hours or more of intense sun in the Mediterranean. The more sun a lavender receives the stronger the aroma from the leaves. Lavenders do not grow well in the shade.
Lavender grows in open areas and tolerates blazing sunshine in the South of France which is where most commercial lavender is grown.
The lavender smells the strongest and flowers the most in sunny conditions, with the hottest and driest years, yielding the highest concentration of essential oils for the commercial lavender industry.
If the lavender is in too much shade then it tends to grow leggy with fewer flowers and less fragrance. Find the sunniest area of your garden or patio to locate your potted lavender.
(Read my article, why lavender isn’t flowering?)
Does Potted Lavender Require Fertilizer?
Lavenders have adapted to growing in soils with a high sand or grit content that is relatively low in fertility and it is in these conditions that lavender thrives.
Additional fertilizer is contrary to the preferred conditions to which the lavender has adapted and actually is likely to harm your lavender.
With added fertilizer lavender displays fewer flowers and the concentration of essential oils in the leaves (which is responsible for the aroma) is much lower.
Lavender also grows droopy and is much more vulnerable to pests and disease when there is excess nitrogen in the soil.
To get the best out of your potted lavender, recreate the lower fertility conditions of its native Mediterranean range by using a potting mix that is at least 30% horticultural sand or grit to promote flowering and avoid using any fertilizer as this can harm your lavender.
Pruning Lavender in Pots
Lavenders of all varieties require an annual pruning to increase longevity and to prevent a leggy appearance. Prune the top third of the lavenders growth either in the early Spring or Fall back. Aim for a rounded, compact shape to helps resist weather better and ensures the lavenders flowers are displayed evenly.
Lavender only displays flowers on new growth which is why I personally recommend pruning your lavender in early Spring usually in March or April.
Pruning in Spring helps to stimulate lots of new growth from which more flowers can be displayed.
I have personally experimented with pruning in the Spring and Fall and I have universally seen more flowers on the lavender I prune in the Spring thanks to all the new growth as well as a stronger fragrance.
Prune the top third of the lavenders growth every year to prevent the lavender becoming leggy as once it is leggy and out of control it displays fewer flowers and does not live as long.
Avoid pruning into the older woody part of the lavender nearer the base as this older wood does not grow back.
Watch this YouTube video for a visual guide on pruning potted lavenders:
If you do not prune lavenders annually they grow leggy with fewer flowers and do not live as long.
How to Increase Lavender Flowers
To increase the number lavender flowers, plant lavender in a low fertility, well draining, gritty potting mix, and place your lavender in an area of as much sun as possible. Lavender flowers on new growth, so prune lavender at the start of Spring to encourage new growth which displays more flowers.
Lavenders flower most and exude the strongest fragrance in the hottest, sunniest and driest years in the native Mediterranean range.
Whilst you do not need a Mediterranean climate to grow lavenders that display lots of blooms you do need to emulate their ideal conditions.
- Place your potted lavender in the sunniest spot of your garden. Lavenders prefer at least 6 hours of sun or more for the best growth, fragrance and flowers.
- Plant lavenders in the recommended gritty potting mix (at least 30% sand or grit by volume). This balances the fertility of the compost to mimic the typical soil fertility of the lavenders native range which promotes flowering. If the potting mix has been enriched with nutrients the lavender grows fewer flowers and the essential oils (which are responsible for the fragrance) are less concentrated so the lavender does not smell as strong.
- Prune lavender in the Spring. Lavender blooms on new growth and pruning at the start of spring stimulate lots of new growth which increases flowering.
Lavender flowers more in years of higher temperatures and more sunlight which is beyond a gardeners control. However it a great tip that I picked up from commercial lavender growers is to use a white stone mulch around your lavender or place it in an area of your garden that reflects a lot of light (such as a patio with light colored slabs).
This reflects more light onto your lavender, increasing the brightness and increasing the flowering and aroma. More light and heat also helps to increase evaporation from around the foliage which reduces the risk of fungal disease.

When does Lavender Flower?
| Lavender Species: | When Does it Bloom? | How Long Does it Flower For? | Popular Varieties: |
| English Lavenders: | Mid June/July. | Blooms for 4 weeks. | ‘Munstead‘ and ‘Hidcote‘ |
| French Lavenders: | As early as May until Septembers. | Blooms for up to 3 months in optimal climates. | ‘Regal Splendor’ ‘Ballerina’ and ‘Anouk’ |
| Hybrid Lavenders: | June/July | Blooms for up to 2 months. | ‘Grosso’ and ‘Provence’ |
English lavenders flower in mid June and with elegant blue flowers that last for about a month or so.
Whilst English Lavender does not bloom for as long as French lavenders, they are much more cold hardy, live for a 15 years or more, have a finer fragrance and popular varieties such as ‘Hidcote‘ and ‘Munstead‘ staying a more compact size making them ideal for pots and containers.
French lavender flower for much longer and can flower for 3 months in a Mediterranean climate but the fragrance is less strong.
Hybrid lavenders such as ‘Grosso‘ can flower for around 2 months starting in June or July and exude a strong fragrance although they tend to grow rather large so may need repotting more often.
Potted Lavender Care in Winter
How to care for your potted lavender in Winter depends more on the specific species of lavender due to variability in their tolerance for cold conditions.
English lavenders can be left outdoors in Winter in a sunny location and can survive in freezing temperatures, if they are in a well draining potting mix. French lavenders do not tolerate frost and freezing temperatures and the pot should be brought indoors before the first frost of Winter.
English lavenders and some of the hybrid lavenders such as ‘Grosso‘ are the only lavender varieties that can really tolerate cold and snow as long as the soil is well draining.
However it is still important that you prune your potted lavenders annually as a leggy lavender has a greater tenancy to break up or become damaged under the weight of snow whereas compact lavender resist weather much better.
Do not water you lavender during Winter as this is the time at which lavender is at highest risk of root rot which is prevalent in cold damp soils.
This highlights the importance of good drainage with a good gritty potting mix to allow excess moisture to drain away from the roots efficiently.
If you are in a particularly cold climate, plant lavenders in larger pots or containers is often better as larger pots have a greater capacity for soil which acts as insulate for the cold sensitive roots in the Winter and increase the survival rate of lavenders.
In cold climates bring your potted french lavenders indoors over Winter an place them in a sunny Window.
Ideally locate them in a heated green house which maintains a temperature above freezing and the lavender can benefit from as much light as possible.
Water indoor lavender once every 4-6 weeks with a thorough watering during Winter to sustain the lavender until Spring.
Personally I recommend growing English lavenders in pots in cold climates as they are much easier to maintain, particularly if you do not have the space to bring pots indoors in Winter.
(For all the best practices read my article on caring for lavender over Winter. I also have a specific article on caring for French lavenders which require more care and attention over winter then other lavenders).
Key Takeaways:
- Lavender ‘Hidcote‘ and ‘Munstead‘ are the best lavender varieties for growing in pots. Lavender ‘Hidcote‘ and ‘Munstead‘ are cold hardy, so can be left outdoors all Winter, produce lots of fragrant flowers and stay a compact size that is proportional to the pot or containers.
- Ceramic, clay and terracotta pots are the best pots for lavenders as they are porous which lets the soil dry out evenly. Choose a pot that is at least 12 inches across to ensure the pot has the capacity for enough soil to insulate the lavenders roots in Winter.
- Lavender is a drought resistant herb that should only be watered when the soil has dried out around the roots. Water lavender thoroughly so that excess water trickles from the base of the pot then wait for the soil to dry before watering again.
- Water newly planted lavender once a week for the first year to promote good root development then water once every 2 weeks after a year once it has establishes. Do not water outdoor potted lavender in Fall or Winter as they attain all the moisture they require from the environment.
- Plant lavender in a potting mix that is 70% compost and 30% horticultural grit or sand. The gritty potting mix ensures the soil has a porous, aerated structure that allows for good drainage, and emulates the lower fertility soil conditions of the lavender native environment.
- Place potted lavender in an area of full sun (at least 6 hours or more). The more sun your lavender receives the more flower it displays and the stronger the fragrance from the foliage. Lavender do not grow well in the shade.
- Potted lavender does not require any fertilizer. Lavenders are adapted to gritty, low fertility soil in their native Mediterranean environment in which they thrive. Fertilizer causes lavender to display fewer flowers, decreases the fragrance and grow droopy.
- Prune lavender in the either the early Spring or late Fall after flowering. Prune lavender annually to prevent a leggy appearance and to increase longevity. Prune back the top third of the lavenders growth into a compact rounded shape to promote flowering.
- English lavender flowers in June/July and the blooms last for around 1 month. French Lavenders bloom in May and can last around 3 months in optimal conditions. English lavenders have a more pronounced aroma then French Lavenders
- English lavenders are cold hardy and can be kept outdoors in pots all year, whereas French lavender are cold sensitive and die back due to frost and freezing temperatures. Bring French lavender indoors before Winter. Do not water outdoor lavenders in Winter, but water indoor lavenders once every 4-6 weeks.
