Why Won’t My Dahlias Bloom?

By: Jessie Keith

Why Won’t My Dahlias Bloom?

“I have tried everything to grow Dahlias. They come up sometimes to about 1ft and never bloom.” Question from April of Dresden, Tennessee

Answer: I am sorry to hear that you are having trouble with your dahlias flowering. There are several factors that impact dahlia blooming, including light levels, fertilizer, and dahlia type. First, provide them with full sun–eight or more hours per day is best. Feed your plants with a quality fertilizer formulated to encourage flowering to boost blooms. Finally, choose more compact dahlias with a free-flowering nature. Try varieties in the Gallery Series, which are more compact and flower nonstop. Dahlias in the Happy series are also outstanding when it comes to repeat bloom. Happy Single Flame is especially pretty with its hot pink and yellow single blooms. For more information, I encourage you to read the following blog and watch our video about growing Dahlias to perfection. (Click here to read All About Growing Dahlias.)

Happy Dahlia growing!
