Can I grow lavender in a container on the wall of my balcony? If so, what type of soil should I use?
You can certainly grow lavender in a container but it has a large root system so an oversize container is necessary and this may preclude hanging it on your balcony wall. A single plant can spread 24 inches and grow up to 2 feet. As it’s a Mediterranean plant it wants lots of sun – at least 4 hours of direct sun a day. If you can provide this on your balcony it should do just fine. Ensure your pot has a good drainage hole at the bottom and use a commercial soil mix designed for containers to ensure good drainage. It should be allowed to dry completely between waterings and will tolerate some drought – another factor making it balcony-friendly. Best watered in the morning so the sun can dry it’s leaves. If you are able to winter it over, cut it back to about 8 inches in the spring. After 2-3 years, lavender becomes quite scrubby and will need to be replaced. Hidcote and Munstead are the varieties recommended for the Toronto area.
