Care essentials

Light

Plant petunias in full sun (at least 6 hours daily); in NE Florida grow them as a cool-season annual from October through April, when lower sun angles and milder temperatures allow peak performance.

Water

Keep soil consistently moist but not waterlogged; water at the base to keep foliage dry and reduce disease. Container petunias may need daily watering during warm spells; back off during cool, overcast weather.

Soil & Fertilizer

Grow in well-drained sandy or loamy soil amended with compost. Petunias are heavy feeders—apply a balanced water-soluble fertilizer every 2 weeks throughout the bloom season for continuous color.
