Dahlia Bulbs

What Are Dahlia Bulbs?

Dahlia bulbs, also known as tubers, are the underground storage organs of the Dahlia plant. Unlike classic true bulbs like tulips, these tuberous roots hold energy for stunning floral displays in summer and autumn. Dahlias come in many varieties, shapes, and sizes, making them a favourite for Kiwi gardeners wanting a burst of cheerful, long-lasting colour.

Each Dahlia bulb produces one or more stems, topped with a profusion of blooms from midsummer until the first frost. Gardeners can select from hundreds of varieties, including iconic forms like cactus, decorative, pom pom, and dinner plate dahlias. Explore unique options such as the Dahlia Pom Pom Mixed (Dahlia Pom Pom) for intricate, globe-shaped blossoms in a range of colours.

Planting and Growing Tips

Plant Dahlia bulbs in spring once risk of frost has passed. Choose a sunny, well-drained spot in your garden, and plant tubers about 10cm deep and 30-60cm apart. Dahlias need fertile soil and regular watering, especially during dry spells. Stake taller varieties to protect them from wind and to keep blooms standing tall.

Once established, your Dahlia bulbs will reward you with months of colourful blooms – perfect for cutting gardens, beds, or containers. For more expert planting tips and advice, check out our handy gardening tips and tricks.
