Growing Petunias in Zone 9A

Petunias are workhorses of the summer garden — blooming nonstop from spring to frost with minimal fuss in sun or containers.

Zone 9A has a very long growing season with mild winters. Many crops can be grown nearly year-round with successive plantings.

Top Growing Tips

• Start indoors 10-12 weeks before last frost — tiny seeds need light to germinate
• Deadhead regularly or cut back hard mid-season to rejuvenate blooms
• Trailing wave types are spectacular in hanging baskets and window boxes
• Grandiflora types have bigger blooms; multiflora types are more weather-resistant
• Fertilize every 2 weeks with balanced fertilizer for continuous bloom

Companion Planting

Good companions: tomatoes, peppers (deter aphids), beans

Avoid planting near: Heavy shade

Harvest Timeline
