BEST LAVENDER TO GROW INDOORS:

Of all the types of lavender, the best type to grow indoors is french lavender.  More specifically, the Lavandula cantata, because it is a smaller variety that doesn’t get too big.  

The French Lavender species can withstand the changing temperatures within a house and will flower more than other types.

This extensive flowering is because the change in house temperature mimics the seasons that a French lavender plant goes through to successfully produce flowers.

HOW TO CARE FOR LAVENDER PLANTS IN POTS:

SIZE OF POT

The first thing you need to decide for your lavender plants is how big of a pot and what size plant do you want. Lavandula angustifolia, or English lavender as it’s commonly referred to in the US, does best in smaller pots around six inches deep by twelve inches wide. 

Larger varieties such as Lavandula dentata or French lavender will do fine in a pot that is twelve inches deep and wide. 

DRAFT FREE AREAS

Keep your plants away from drafty areas, such as doorways where it might be cool at night if the temperature drops below freezing. 

If you have no choice but to place them near a window, make sure they are not exposed to cold winter drafts, as this can impact their growth.

SUNLIGHT

Consider the amount of sunlight your lavender plants will get during the day when choosing a pot and plant size. 

Lavandula angustifolia or English lavenders do well with four hours or more of direct sun, while larger growing varieties such as French lavender may need six to eight hours of bright light.

WATERING

Lavender plants are very drought tolerant, so they don’t require much water at all.

When watering lavender, you want the soil to dry out a bit before your next watering. 

For most varieties, this means about 20-25 minutes with an automatic drip irrigation system once every five days.

Too much watering will cause root rot and other diseases, so finding the correct balance is key. 

FERTILIZER

Be sure to fertilize your lavender plants in early spring and mid-fall. 

Lavender plants are heavy feeders, so fertilizing will keep your plant healthy and strong. 

You can use a general-purpose fertilizer such as 20-20-20 and follow the directions for indoor houseplants on the package. 

You can also make your own fertilizer concoction with fish emulsion (available at most garden centers), mixed half and half with water.

GROWING LAVENDER IN POTS  

Follow these steps for success:  

-Pick out the best pot for your space and species of lavender. 

-Choose an area of the house with plenty of natural light. 

-Place in a sunny spot near a window or door that gets lots of sunlight throughout the day (but not direct sun). 

-Put 1/2 inch gravel or small rocks at the bottom of your pot before you plant anything. Having material at the bottom of your pot will help with drainage and prevent root rot from the soil being too wet. 

-Fill pot about 2 inches deep with soil mix, then place plant in center and fill around base until soil.

HOW TO HARVEST LAVENDER

CUTTING BACK YOUR PLANT

Lavender plants can grow up to three feet tall but usually only grow to one foot. 

As your lavender plant matures it will become woody and lose its lacy foliage, but don’t worry as this means the blooming is coming soon! 

Once those first flowers appear in early summer you can cut them back to a few inches off of the ground and enjoy their beautiful fragrance throughout the home.

HARVESTING LAVENDER

Harvesting lavender is as easy as cutting the flower stems off at their base with a sharp, clean knife or pair of shears.

Pruning twice a year will keep your plant healthy and vigorous. 

The harvested flowers can be used for oil distillation and sachets. 

Leave enough crop behind to ensure the plants will continue to grow well. Harvest one plant at a time so that it does not stress them unnecessarily.

WHEN TO HARVEST LAVENDER

The best time to harvest is before midday on dry days with no wind. If you’re planning on using your lavender for essential oils, a morning harvest ensures the most potency.

Harvest your crop when the flowers are in full bloom. 

This is usually early summer after the plants have flowered for at least a month.

CAN YOU HARVEST LAVENDER AFTER IT HAS BLOOMED?

You can harvest lavender after it has bloomed. Doing this when it is dry outside can actually speed up the drying process because the plant has already started to dry out.

When you harvest lavender after it has bloomed, it won’t be as potent for making essential oils, but it can be perfect as an option for potpourri.  

WHAT TO DO WITH DRIED LAVENDER

Once you have dried your lavender (you should be able to run your fingers down the stem and have flower buds fall off), you can decide what you want to use it for.

Dried lavender is a great decoration and ingredient for your home. You can get creative and make some beautiful sachets or potpourri. It will not only smell amazing, it also makes a unique gift as well.

LAVENDER GROWING SEASON

Lavender has a long blooming season which begins in May and lasts until October. However, you want to time your harvesting of lavender flowers before the end of July as this will allow the bush enough time for its leaves and stems to grow and produce more flowers for the next season.

TROUBLESHOOTING: WHY IS MY INDOOR LAVENDER PLANT WILTING?

If your lavender is wilting, it is most likely due to overwatering.  Stop watering and give the plant a chance to recover.  Then, follow a strict watering protocol of watering one to two times a week for young plants that aren’t yet established, every two to three weeks for mature plants until buds form, and then one to two times weekly until you harvest the flowers.
