Gardener Tip: Insufficient sunlight is the primary reason Grandiflora Petunia refuses to flower. Even a partially shaded spot that looks bright to the eye can be too dim for reliable blooming — if your plant is producing lots of leaves but no flowers, moving it to a spot that gets at least 4-5 hours of direct sun is the first thing to try before adjusting anything else.
