Lavender Plant in Pot: A Beginner's Guide to Growing

Growing a lavender plant in a pot can be a wonderful experience, especially for beginners.

Lavender plants prefer well-draining soil and full sun to partial shade, which means they need at least 4-6 hours of direct sunlight per day.

To ensure your lavender plant gets the right amount of sunlight, place it in a south-facing window or on a balcony that receives plenty of sunlight.

Lavender plants are relatively low maintenance and only need to be watered when the soil feels dry to the touch, which is usually every 7-10 days during the summer months.

English lavenders are more cold-tolerant than other lavender varieties, making them a good choice for climates with cold winters.

If you have limited space, try compact cultivars such as 'Hidcote', Sweet Romance, and 'SuperBlue' for a more manageable option.

Spanish lavender is less cold hardy than its English cousin, but more tolerant of heat and humidity than other lavenders.

Compact varieties of French lavender are also perfect for growing in containers, which is a good option in areas where the plant isn’t hardy.

Dwarf and other compact varieties that don’t grow larger than a foot tall and wide will take up the least space and offer easier portability.

Some of the best lavender choices for container growing are tender or half hardy varieties, as well as a few dwarf cultivars.

Here are three popular cultivars that are well-suited for growing in pots:

Your local garden center can advise you on the best cultivars for your climate, or contact your area’s local extension service for more specific information on which types of lavender are best for your region.

Lavender grows best in slightly alkaline soils, so amend your potting mix with a tablespoonful of dolomite lime to boost the pH.

You can also use average potting soil or mix in cactus or moisture-controlled potting soil to keep it drier.

To ensure proper drainage, choose a pot with ample drainage holes, and consider adding coarse sand, vermiculite, and perlite to the potting mix.

Here are some ingredients you can mix into your potting soil for improved drainage:

Lavender pots need to be large enough for the soil to insulate the plants' roots and still drain easily.

To grow a healthy lavender plant in a pot, you'll want to choose the right container. A pot with several drainage holes at the bottom is essential to prevent water retention and root rot, so look for one made of unglazed terracotta or clay.

For the best results, select a container that's at least twice the width and depth of the rootball, giving your plant plenty of room for future growth. A large square, rectangular, or round pot is a good choice, as they provide better stability than cone-shaped pots.

To ensure good drainage, you can also add coarse sand, vermiculite, and perlite to your potting mix. This will help prevent root rot caused by soggy soil.

Choosing a pot for your lavender plant is crucial for its health and well-being. Good drainage is essential, so choose a container with several drainage holes at the bottom.

Pots made of unglazed terracotta or clay are a great option because their porous walls allow for better airflow and help prevent water retention. Avoid cone-shaped pots, as they can be unstable.

A container that is at least twice the width and depth of the rootball will give your plant plenty of room for future growth. Consider the size of your lavender plant at maturity when choosing a pot.

Here are some guidelines for choosing the perfect pot:

Large square, rectangular or round pots provide better stability than cone-shaped pots and must have plenty of drainage holes.

Planting lavender in a container requires some thought to ensure it thrives. Choose a container with several drainage holes at the bottom to prevent water retention and root rot.

Good drainage is essential for potted lavender, so select a pot made of unglazed terracotta or clay, as these materials allow for better airflow. Consider your lavender plant's size at maturity when choosing the best size for your container.

A container that is at least twice the width and depth of the rootball will give your plant plenty of room for future growth. You can also grow your potted lavender indoors; find a place like a windowsill that receives even more direct sunlight, at least 8+ hours per day.

Lavender is a dryland native, so its roots demand loose soil with excellent drainage. Fill the container two-thirds full of potting soil that is paired with a pot that has ample drainage holes. Tamp the soil to eliminate large air pockets.

To replicate the loose, sandy soils that lavender is native to, consider adding some perlite or coarse sand to your potting mix. Another option is to purchase a pre-blended potting mix specifically formulated for growing lavender plants.

Here are some key points to consider when planting lavender in a container:

Lavender plants like it sunny and dry once established, so you can reduce watering to every 1-2 weeks, depending on climate, sun exposure, and soil composition.

Water your potted lavender thoroughly until the soil is completely moist, but avoid soggy soil, which lavender won't tolerate.

You can check the soil moisture by poking in a finger about 2 inches below the surface, or by using a light layer of small pebbles on top of the soil to help retain moisture.

Lavender plants thrive in poor soils, but potted plants quickly use up all available nutrients, so you may need to fertilize occasionally with a liquid organic seaweed or kelp solution.

Repot your plant about every two years with new potting medium to replenish nutrients, ideally before new growth begins in spring in a pot about 2 inches larger.

Watering when the soil is dry to the touch an inch below the surface is key, as lavender is drought-tolerant and overwatering is the most common cause of its demise.

You can water your potted lavender every 1-2 weeks, depending on climate, sun exposure, and soil composition, and be sure to check the moisture level regularly to avoid overwatering.

It's essential to avoid wetting the leaves or foliage when watering containerized lavender, and never let the plant sit in water, as this can lead to root rot and kill the plant.

A good way to check the moisture level is to stick your finger knuckle-deep into the soil and then water if it feels dry, but be sure to check the moisture level on a regular basis, since container-grown plants can dry out quickly.

Prune and deadhead your potted lavender regularly to maintain its desired size and shape.

Prune your lavender in late summer, right after it has finished blooming, to prevent woody stems from developing. If you have a variety that blooms with a big flush in late spring, prune it then to delay this process.

Cut your plant back by about 1/3 the length of each stem, sculpting it as you go to remove leggy growth. Be careful not to cut back into the older, woody sections of the plant, since lavender will not regrow from old wood.

Deadheading the flowers after they have faded can also be beneficial, keeping your plant tidy and encouraging more flowers and extending the blooming period.

Potted lavender can be pruned back to its woody stems in autumn to help young plants direct energy back into the roots.

If you live in a zone where winters are harsh, you should move your potted lavender into a garage, shed, or other indoor shelter for overwintering. This is especially true for more tender varieties like Spanish and French lavenders, which need protection in areas with cold winters.

Even cold-hardy English lavender (Zones 5-9) can benefit from some protection in areas with harsh winters, as potted plants are more vulnerable to the cold.

To ensure the survival of your lavender plants, choose an unheated but not freezing indoor shelter. This will allow them to experience a period of dormancy in cooler temperatures, which is necessary for them to flower the following season.

Cut back on watering during this time, as your plants will be dormant and won't need as much moisture.

Here are some general guidelines for overwintering potted lavender:

Note that some lavender varieties can live in a container for many years with proper care, but the lifespan can vary depending on the specific variety.

Lavender has few pest or disease problems, but one issue to watch out for is root rot from overwatering.

Checking the soil moisture an inch below the surface before watering is crucial to avoid overwatering.

Don't water your lavender plant unless the soil is dry, as this can lead to root rot.

Allowing pots to stand in water-filled pot saucers is a big no-no, as it can cause the roots to rot.

It's best not to use a pot saucer when growing lavender in a container, as it allows the water to drain freely.

A unique perspective: When to Water a Jade Plant

Lavender plants need full sun to thrive, so choose a spot that receives at least 6 hours of bright, direct sunlight daily.

To prevent soggy soil, allow your potted plants to dry out between waterings, and check the soil regularly by poking in a finger.

A light layer of small pebbles on top of the soil can help retain moisture while preventing the soil from becoming soggy.

Lavender plants are adaptable and can thrive in poor soils, but potted plants quickly use up all available nutrients, so fertilize occasionally with a liquid organic seaweed or kelp solution.

Repotting your plant about every two years with new potting medium replenishes nutrients and gives your plant a fresh start.

If you live in an area with harsh winters, consider moving your potted lavender into a garage or other unheated shelter for overwintering.

Keep in mind that most lavenders don't like humidity, so avoid growing them in a steamy bathroom or other area with high humidity.

To give your potted lavender the best chance to thrive, choose a variety that's compact or dwarf, as they require less maintenance and are less likely to outgrow their pot.
