Growing Lavender Inside Properly

Can Lavender be grown inside?

The lavender plant can be grown indoors , provided they’re located near an area that receives at least 6 hours of sunshine every day. The soil used for potting must be amended to ensure good drainage. Indoor lavenders should be watered only once every two weeks throughout the growing season in order to remain healthy and to produce flowers.

The dwarf varieties of lavender work best in indoor settings such like Lavender Hidcote and Lavandula angustifolia because they keep an upright shape (if properly pruned) and produce beautiful flowers and attractive foliage.

Indoor lavenders have particular requirements for successful growth, so read on for tips on how to:

  1. Select the best pot for indoor lavenders
  2. The best potting mix for lavender (70 percent potting soil, 30 percent grit or sand)
  3. The most ideal rooms to grow lavender (avoid bathrooms, kitchens and any other areas with high humidity)
  4. How often and how often to water your indoor lavender (avoid excessive watering).
  5. Prune lavender regularly to keep it in shape and encourage flowers.

Choose the Right Pot for Indoor Lavenders

The lavenders’ roots prefer to be kept neat clean and dry in between watering. Therefore, lavenders require a pot that includes drainage holes in the base to ensure that water is able to escape easily.

It is recommended to select the pot that is larger and deeper than the container it was initially in at the garden store. The smaller varieties of indoor lavender aren’t as fast or as large as the varieties grown outdoors that are harvested and therefore you shouldn’t need to pot the plant frequently.

Every now and then you must look for the appearance of lavender roots from the drain holes in the pot. If this occurs, you’ll have to transplant the lavender in a larger pot to ensure that the drainage holes don’t become blocked, which can block the water from draining.

The best time to repot lavender is in the early spring, as this can reduce the shock of transplant. It is possible to repot your lavender anytime during the season, but you might have to cut back certain flowers if you potting flowers outside the ideal time of the spring season as they require time to adapt to their new surroundings.

One of the biggest errors I have observed with the cultivation of indoor lavenders is that people put the lavender in a pot that has adequate drainage, but then put the lavender in a larger decorative pot, or put it on top of a saucer to collect the water so that it won’t run out and cause an mess.

The saucer or decorative pot is then filled with water, which helps keep the soil moist, and the roots then begin to rot.

What can I do to prevent water from leaking out of from the window is put my lavender in a larger decorative pot, but leave the lavender from its smaller pot to water it and then leave it in the pot for about 30 minutes to ensure that the extra water is given time to evaporate.

I then put the lavender in the pot to decorate it with newspaper towel at the bottom of the pot to absorb more moisture. I also ensure that the soil will remain dry, which is lavender’s preferred state.

The Right Potting Mix for Indoor Lavenders

The best lavenders and the more flowers in well-drained sandy soil with moderate to low levels of fertility, as these are the conditions in which they have adapted in their Mediterranean home region.

To grow your indoor lavender in a successful manner it is necessary to try to replicate the soil conditions that ensure that the plant is well-nourished and full of scent.

Make a mixture of general potting soil as well as Sand or grit. A mix of 70 percent potting mix and 30 percent grit or sand will give the proper soil structure to allow water to drain efficiently so that it can keep the roots mostly dry during periods of watering.

The air pockets formed by sand or grit (both materials are effective) will let the roots establish remain dry, and avoid soil compaction.

When you transplant your lavender in the new location, avoid firming the soil around your plant too hard since lavenders like an open soil texture.

Do Indoor Lavenders need Fertilizer?

Contrary to what you believe, lavenders thrive in low to medium quality soils that are sandy and with little nutrients due to its Mediterranean tradition.

So indoor lavender is a flower that does require no additional feed. If the lavender is located in a high-nutrient soil or receives an additional fertilizer, then the growth of the foliage is encouraged with the loss of the flowers. The lavender may develop an look of a leggy plant and may show the leaves turning yellow.

Watering Indoor Lavender

The most frequent mistake made when it is time to water indoor lavender is to over-watering, rather than under watering.

Lavenders have adapted to the dry, hot and sandy climate in the Mediterranean and thrive in the absence of watering infrequently.

This resistance to drought and toughness is the reason lavenders are excellent low-maintenance indoor plants to cultivate.

If you water it often enough, it can appear droopy and may show some browning in the foliage that is a sign of stress due to excessive the amount of watering.

These signs usually signify root decay. (see my article on ways you can revive the dying flowers of lavender).

The watering of indoor lavenders requires some time and care in the beginning, but once they’ve established, you’ll only have to water them once every two weeks throughout the blooming season.

The Ideal Place for Indoor Lavender

The lavenders are able to enjoy full sun with good air circulation and warm temperatures within their natural habitat. The best place to plant your lavender is an area that is sunny and gets 6 or more hours of sunlight in the summer months.

Lavenders are able to survive in less sunlight, but they can become unbalanced and produce less scent and less flowers during the summer and spring when they are exposed to more sun It is always recommended to plant lavenders on the windowsill in the most sunny room of your home.

Lavenders don’t do well in complete shade or in indirect light.

Indoor lavenders can be grown comfortably in hot temperatures, and they can be grown indoors during winter , provided they aren’t exposed to frosts in greenhouses for instance.

Spacing Indoor Lavender

The smaller indoor lavenders require space of their own to let air flow through the leaves, so not overcrowd them with any other plants or items and place they are placed about 9 inches from each other.

The airflow that is allowed to flow through the home with an open window during summer is beneficial to the lavender because it keeps the foliage dry and will help prevent fungal diseases.

Rooms to Avoid for Lavender

It is best to avoid placing lavenders in areas that are too hot, like the kitchen or the bathroom. The lavenders can thrive in the Mediterranean climate that is characterized by lots of sun, heat and lack of constant humidity throughout the day.

If they are subjected to continuous high humidity , they may be susceptible to fungal and root rot. As long as they’re in a sunny window free of moisture, they’ll be safe.

Pruning Indoor Lavenders

Pruning lavenders is vital to keep the lavender’s shape as well as to stimulate growth and increase the number of blooms since lavender flowers only when the growth is new which is why it is important to cut back your lavenders each year.

The best time to trim is in the beginning of spring when the first green leaves begin to emerge at the base of lavender. Cut the green top growth back about 1/3, keeping in mind that you want to maintain the plant in an well-ordered shape to prevent it from going through a split and becoming hard to handle.

One of the most crucial things you need to be aware of when cutting lavender is to not cut back the brown, woody base of the lavender because old wood stops producing new shoots. This means that no new blooms can be produced and the plant will eventually die.

A second cut in fall is suggested to eliminate the flower stems that have faded and to make sure that the lavender keeps its shape.

For indoor dwarf varieties like Lavandula Angustifolia as well as Hidcoteyou make use of a sharp, sterilized pair of scissors, without having to use pruners since the growth of varieties that are suitable to indoors is typically more delicate and less difficult to cut than the more large and more vigorous varieties for outdoor use.

The process of pruning indoor lavenders is basically similar to the outdoor variety, but it is reduced to size.

Key Takeaways

  • Select a pot that has good drainage holes at the base and don’t let water collect beneath the saucer, as this can keep the soil wet and cause root rot.
  • Grow indoor lavenders in the potting mix which is approximately 20% sand or grit, and 70 percent general potting soil. Sand will aid in drainage and create the ideal soil structure to allow lavenders to flourish.
  • There is no need to fertilize your lavender plants as they thrive in medium to poor fertility soils. A high fertility can encourage foliage growth , but however, it will not produce flowers.
  • Place your indoor lavender in a way that there is a little air flow. Avoid humid or steamy rooms like bathrooms or kitchens since lavenders like to be dry.
  • The lavender in your indoor garden should be watered once a week for the first 4 weeks to avoid the shock of transplantation. After four weeks, you can begin regular watering every two weeks during the season of growth. It is recommended to water every 4-6 weeks in the winter.
  • Cut back indoor lavenders in early spring to encourage blooms keep them in shape and keep that the plant from turning too hard.
