How to Plant Tuber Flowers


The potato, a commonly known tuber, is one of the easiest vegetables to plant and cultivate. Growing tuber root flowers is as simple as potatoes, and requires a few of the same basic tools and skills to get started.

Step 1

Tubers are a fleshy root system, generally connected at the top by eyes forming the buds and from which stems grow. To divide tuberous roots for more plants, use a sharp gardening knife to cut the tubers into sections, ensuring that each one has an eye at the top of the root. Division should take place in the spring just prior to planting.

Step 2

Choose a location with good drainage. Dahlias like full sun, while tuberous begonias, caladium, and elephant ears prefer partial shade.

Step 3

Planting depth for tubers varies depending on the variety you plant. Tuberous begonias and caladiums should be planted about 1 inch deep with the eye or buds facing up. But place begonias 1- to 2-inches apart, while caladium tubers need 8- to 12-inches between each root. Dahlia tubers should lie just below the soil with buds peeking out above ground level. Space tubers for small dahlias 2 feet apart, and leave 3 feet between tubers for large dahlias. Elephant ears, like caladium, are grown for beautifully textured and colored leaves. Plant elephant ear tubers deeper, about 4- to 6- inches deep allowing 2- to 3-feet between each tuber.

Step 4

Most tubers require moist soil that is not soggy, so water accordingly--especially during dry, hot weather.
