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.’

Lavender plants contain a small amount of Linalool which, while not toxic in small quantities, may prove fatal if a large quantity of lavender is consumed.
