Frequently Asked Questions

Why do container Petunias need daily watering in summer?

Containers dry out fast in heat, and Petunias are heavy drinkers during active bloom — daily watering in hot weather keeps them from wilting and helps sustain continuous flowering.

How long does Petunia keep flowering?

From spring until frost — these versatile, free-flowering annuals provide one of the longest continuous bloom windows for hanging baskets, containers, and borders.
