Do dahlias prefer sun or shade?
Sun and Shade: Dahlias are sun-lovers and need a minimum of 6 hours of sunlight per day. The more sun they get, the better they’ll bloom, so it’s best to plant your dahlias in the sunniest location possible. Zone: Though dahlias are only winter hardy in zones 8-11, gardeners in zones 3-7 can grow dahlia as annuals.
Do dahlias return every year?
The tubers that grow beneath the ground are unharmed and can live to perform again year after year given a little care from you. Some lift dahlia tubers and store them over winter, then replant the following spring. Others in milder areas leave them in the ground.
How do you care for outdoor dahlias?

What happens if you don’t divide dahlias?
When you divide the tubers, it is important that each tuber has part of the original tuber stock along with a neck, body and eye. Without these parts, you will not be able to grow a new dahlia plant.
