How to Grow Lavender in Containers
Growing lavender in containers is quite simple, and is actually easier than growing lavender in plots. The main things to consider are the size of container, the plant receiving adequate light, proper watering and drainage, and lastly some pruning and feeding. By following these simple steps, you can enjoy the fresh and relaxing scent of lavender throughout the rest of the hot summer months.
Start your lavender from seedlings and not seeds, as seeds need a lot of extra effort on your part just to germinate. Lavender also prefers tight root spaces in well drained soil. The container should not be more than two inches larger than the root system.
Lavender prefers hot and dry climates. Locate your lavender containers in a sunny location — somewhere that gets a steady supply of sunlight, about 8 hours a day. If you live in California, consider yourself lucky, as the climate there resembles the Mediterranean — where the lavender plant originated.
The pot should have adequate holes to make sure that water drains well. Pot soil should be a light and and well aerated, not dense and compact. Add an inch or two of gravel to the bottom of the container to improve drainage as well. Acoid overwatering as it may kill the plant! Just give your lavender enough water — not too wet, but not dried out either.
Container grown lavender will benefit from a light pruning in the spring, before budding and a light clean up again in the summer. This keeps the lavender from becoming scraggly and also keeps air circulating around the plant.
