Bay laurel plants are easily kept in a pot but can be planted as well. When put directly in soil, these plants can reach heights of up to 40 or even 50 feet tall. Bay laurels need not be kept in moist soil so let the top few inches of your pot dry out before watering again. In your garden this edible plant will grow well in a variety of soils but be sure to provide proper drainage and let the soil dry out somewhat before watering again. Laurus Nobilis is winter hardy up to about -5 degrees celsius. When potted you can bring the plant indoors through winter but be sure to give it a bright spot away from drafts and heat sources. Bay laurel plants are not pet friendly so be careful with your furry friends.
