'The first step when growing lavender indoors is to select the right pot,' advises Rachel. 'Lavender grows best in a breathable container such as terracotta filled with a potting mix mixed with some compost.
'To germinate lavender seeds inside, you need to provide the seeds with consistent warmth and light. For this process, it might be easier to sow your seeds in seedling trays so that you can position your seedlings in windows covered with a plastic bag to ensure the right conditions.'
Lavender can be a difficult plant to grow from seeds as its sprouts often emerge unevenly and can take a while to germinate. 'Keeping them in a controlled environment will help maintain a consistent germination rate,' Rachel says. 'Once germinated it can take one year for the plants to bloom fully, only flowering lighting in their first season.'
How to care for indoor lavender
Lavender is a relatively easy plant to take care of indoors and only needs to be watered once the top few inches of soil have become dry to the touch. When watering, drench the soil thoroughly and allow it to drain, emptying the drainage tray to prevent stagnant water.
'The most important part of looking after lavender plants indoors is to ensure that it gets enough light,' warns Rachel. 'Lavender will do best in a south-facing window where it can get at least three to four hours of direct sunlight a day. To make sure that your plant grows evenly, rotate it every few weeks for even flowering. You may notice weak, spindly stems if your plant is not receiving enough sunlight, and it may be more susceptible to disease,' she adds.
Knowing how to prune lavender is not only for outdoor lavender plants, Rachel says. 'Cutting old stems off of your plant not only helps to maintain its appearance and size as an indoor plant, but also encourages new growth.'
Which lavender is best for indoors?

Is lavender toxic to dogs?
While lavender isn't listed amongst poisonous plants for humans, it is counted as one of the poisonous plants for dogs and is a plant that is toxic to cats, so may not be suitable for homes with pets. Lavender plants contain a small amount of a Linalool which, while not toxic in small quantities, may prove fatal if a large quantity of lavender is consumed. If you have pets, consider placing your lavender plants well out of your animals reach, and avoid leaving your pets alone in a room with toxic plants for a long period of time.
