To keep your Blue Petunia in its best shape, we recommend feeding them every week while they are growing in the summer. For the best and biggest blooms, use a flower-focused fertilizer such as Espoma Flower Tone.
What is The Best Soil for My Blue Petunia?
Petunias requires rich, well-draining soil although it can tolerate a wide range of pH levels and soil types including Clay, Loamy, and Sandy.
How Much Sun Does My Blue Petunia Need?
