7 Easy Steps to Growing Lavender in Pots

Lavender has been one of the most grown herbs by many gardeners for years due to its fragrance, leaf color, medicinal value, beautiful flowers as well as its hardy characteristics. No wonder growing lavender in pots has risen in popularity over the recent past.

Just like mints lavender belongs to Lamiaceae family and can be described as a semi- woody perennial sub- shrub.

This beautiful herb has an amazing potential of staying evergreen throughout the year depending on weather conditions and the location it’s grown.

Lavender is cultivated as an ornamental plant and its fresh flowers can be used in flavoring sauces and desserts.

After you’ve selected the ideal lavender variety, let’s find how to plant them:


How to prepare the soil/mix before pla​​​​nting lavender in pots

Lavender performs well in alkaline, little organic matter, and well-drained soil.

However, with time, the soil becomes compact leading to poor drainage which will in turn bring a lot of problems later on.

To avoid this, do not fill your containers with soil from your garden or bagged topsoil.

You can save yourself the trouble associated with soil-based media by using a recommended "soil-less" blend that will retain moisture and resist compaction. Organic potting soil is a suitable alternative.

The potting mix has a balanced, slow release and regular nutrient supply so your lavender remains strong and healthy throughout the season.


Growing lavender in pots step by step

7 Easy Steps in Growing Lavender in Pots

Step #1: Select the appropriate type and size of growing pot. Be sure to know the mature diameter of the lavender and choose an appropriate container. Lavender is shallow rooted, so the pot does not need to be a tall one.

Step #2: Check out for the pots’ drainage hole which should be at the bottom of the pot.

Step #3: Fill the pot with well-draining soil or organic potting mix at almost the ¾ mark of the pot.

Step #4: Place the lavender in the pot ensuring that the crown is placed slightly above the potting mix. (Approximately 2 cm)

Step #5: Using the remaining potting mix, fill up to few centimetres to the top of the pot.

Step #6: Firm the mix to remove any air pockets and water lightly

Step #7: Use a thin layer of mulch for moisture retention.


Lavender plant care: How to take care of your pot lavender

Water your lavender whenever necessary

Water your lavender when the soil is dry to touch and drench so that water flows freely out the bottom of pots.

Carry out deep watering every 7–10 days for the first two years and as your lavender continues to develop, watering will be required if there is a drought.

 Tip: Lavender is drought resistant so take caution not to over water as this may lead to root rot.

Learn how to water your potted plants and keep them healthy.


Expose your lavender to as much sunlight as possible

Lavender requires up to six hours of direct sunlight per day (full sun).

These hours can either be continuous or broken. The more hours your lavender receives light the better it is for its enhanced blooming and oil production.

To maximize the exposure move your plants around during the day and prune back any trees surrounding your landscape.

You can also use a bright/ white colored mulching material e.g. straw, to reflect sunlight up to your lavender.


Apply mulch to conserve moisture

Apply light mulch up to the plant crown for moisture retention as well as to suppress weeds.

Getting a bright white colored mulch is good for rapid growth and air circulation so your plants dry out fast after watering or rain.

There are several types of such mulches including turkey grit, shells or gravel and straw all at pocket friendly cost.


Remove the weeds regularly

Remove any weed or creeping ground cover regularly to avoid competition for nutrients. Regular weeding also allows good air circulation hence better crop performance.


Apply an appropriate fertilizer

Feed your lavender every week with a balanced water-soluble slow release fertilizer alternatively, you can use fish meal emulsion or compost tea.

Some gardeners use alfalfa pellets (slow-release organic food with triacontanol - a growth stimulant) and do work well too.

Fertilizing lavender too much can hurt it. Don’t over-fertilize lavender as this will only cause harm rather than good to it.

Avoid fertilizer application during the fall because this will make the plant produce tender new growth that will die in the winter.

Tip: Make sure to read the instructions on the label before anything else.


Renew your lavender by pruning

Remove all bud shoots as soon as the little green buds start to form in the first growing season of a newly planted lavender plant.

This helps your lavender to have a vigorous vegetative cycle which encourages a larger, hardy and strong plant ready for surviving the first winter.

Another reason for removing all bud shoots during the first growing season is that you get to enjoy more yield during the second and third year.  

 You can prune during any season but it’s advisable to prune only during the harvesting of lavender bundles to avoid losing valuable buds.

It also reduces the number of times you need to prune your lavender.

Early spring (March through May) is the best time to prune by removing any dead branches all the way down to the plants bottom.

Early spring pruning encourages vegetative growth especially when followed by nitrogen application.

In case of a harsh winter season, prune the entire lavender bush down to the bare woody hedge. After heavy pruning, the plant is likely to be stressed, make sure you do the following;

  • Keep it well watered
  • Fertilize with a nitrogen-rich fertilizer
  • Keep a close watch for pests or signs of disease

Once you do this, your Lavender plants will be back stronger and healthier and give you a few more years of enjoyment.


How to harvest mature lavender

Harvesting lavender is best done early in the morning as the blossoms will retain most of the perfume oils when dried and its fragrance is the strongest then.

Cut the stems slightly above the first set of leaves when the lowest blossom opens since color will be more vivid when dried.

The more you cut blooming stems the more the growth and the plants can flower up to three times during a summer.

Tie the harvested lavender in bundles and hang them upside down in a warm dark place to dry.


Common Pests and Diseases

Lavenders are not easily affected by diseases but fungal infection may occur due to cold wet soils.

If your plant shows symptoms like; yellow, wilting or dying leaves and discolored root tissue, there is a high chance that your lavender has root rot. This disease is caused by over-watering plants hence can be managed by reducing number of times you water the crop.

Although lavender can tolerate most pests, this doesn’t mean that it is completely invulnerable to pests. White flies are very attracted to lavender plants.

They feed on sap from the underside of the leaves and although the may not kill your plant, they usually cause unattractive damages to your crop.

You can control white flies by hand removal or by use of a strong stream water spray especially for adult white flies.

Use of reflective mulch or aluminium foil for mulching is effective in repelling white flies
