How to Grow

Dahlias are grown from tubers (similar to a bulb, but thin-skinned like a potato). Plant tubers in the springtime, about the same time as you would your vegetable gardens or when the ground is warm enough to work up and play in daily. Plant them in a full sun location (giving them 6-8 hours of direct sunlight) and enjoy blooms all summer long. They will bloom and provide you with color and abundant flowers for cutting and enjoying throughout the summer.
The more you cut a dahlia plant, the more it will bloom. Most cut dahlias will last up to 5 days once cut and treated.

Did not come up

Of the 19 Swan Island dahlias I planted in Spring 2020, 16 came up. But the two Shockwave dahlias I ordered failed to even put up the tiniest sprout even though they have the same south facing, sunny exposure. Given how expensive they were, I have to say I was disappointed. Overall, I am impressed by Swan Island, but I cannot recommend Shock Wave unfortunately.
