How to Sow and Plant
+
Sow petunia seeds indoors from February to mid-April at around 20°C in seed trays or from early April to May under cold glass. Once seedlings are strong enough, transplant them outside from early May into sunny spots such as balconies, terraces, or garden borders. For direct outdoor sowing, plant seeds from April to May in well-prepared soil. Maintain adequate spacing to allow growth up to 45 cm tall. Regularly remove spent flowers to encourage prolonged blooming. These vibrant mixed colors thrive best in full sun and will brighten any outdoor area from June through October.
Petunias flourish best in sunny spots, where they receive at least six hours of direct sunlight daily. Regular removal of spent flowers encourages continuous blooming from early summer through autumn. These plants prefer well-drained soil and benefit from occasional feeding with a balanced fertilizer to maintain vibrant growth. Protect them from strong winds and heavy rain to keep blooms intact. With a height of around 45 cm, petunias are perfect for containers, balconies, or garden borders, adding a splash of mixed color that brightens outdoor spaces throughout the growing season.
Start petunia seeds indoors from February to mid-April at around 20°C for strong seedlings, or sow outdoors from April to May once the risk of frost has passed. Choose a sunny spot to encourage vibrant blooms and plant seedlings about 30 cm apart to allow airflow. Regularly remove spent flowers to promote continuous blooming from June through October. These annuals thrive in containers, balconies, or garden borders, adding lively color all summer long. Water moderately and avoid waterlogging to keep plants healthy and flourishing throughout the growing season.
