Yes, you can grow hostas in containers. Hosta leaves come in so many beautiful variations and look great in pots. Also, growing in containers is a great workaround if you have poor soil or suspect you will want to move the plant around to find its best growing location in your garden. Some hostas grow very deep roots (18-inches), so a large, deep container is best. You must keep up with watering and may want to add drip irrigation if you are away in the summer. To overwinter your potted hosta, water deeply before storing, place a piece of hardware cloth (lead-free or stainless steel) with a rock on top of the soil to discourage vermin, and keep in a cool place (not freezing) until spring.
