Deadheading Deadhead petunias as soon as the tubular flowers start to collapse or shrivel and die. This encourages the plant to focus energy on producing more blooms rather than seeds
Pruning Prune petunias regularly to promote bushy growth and more blooms. Cut back older stems by at least one-third to encourage new shoots to form closer to the base of the plant.
Positioning Position petunias in direct sunlight for at least 6 hours a day. If they are in containers or hanging baskets, move them to a sunnier location to boost flower production
Watering Water petunias consistently, but avoid overwatering. For containers, water daily, and for hanging baskets, water until water drains out the bottom
Fertilizing Fertilize petunias regularly with a high potash feed as soon as the first flowers open. Use a controlled-release fertilizer initially and switch to water-soluble fertilizer once established
Trimming Trim back leggy stems to encourage tighter growth and promote more blooms. Cut back up to one-third of the plant volume to rejuvenate it
Fertilizer Application Apply a liquid fertilizer every 2 weeks after planting to encourage vigorous growth and more blooms.
