Dahlias are our key summer focal flowers, and here at Plantpassion we want them to be blooming as soon as possible. As our last frost date is usually Mid to the end of May, we want our tubers to be a decent size to make sure they are flowering by July even if the weather isn't on our side. For more information about growing for efficiency and maximum productivity, do check out The Business of Selling flowers website for more details of our online courses. https://www.thebusinessofsellingflowe...
