Guys, how much sunlight do I need to grow a dahlia?
Don't worry, it's very easy! Just make sure you give it at least 6 to 8 hours of sunlight every day, and it'll produce plenty of beautiful blooms.
At least you must give them 6-8 hours per day, and avoid this plant in shaded areas by trees or building
I think this plant needs about eight hours of sunlight a day to produce lots of blooms.
From what I know, they bloom best with 14–16 hours of light.
