A Florist's Guide to Petunia
Petunias are popular flowering plants known for their vibrant colours and delightful fragrances. They belong to the Solanaceae family and are native to South America. Ideal for gardens, borders, and containers, petunias bring a blend of beauty and charm to any floral arrangement.
Varieties
Petunias come in several varieties, including:
Grandiflora: Large, showy flowers that provide a bold impact. Best suited for garden beds and containers.
Multiflora: Smaller flowers but in greater abundance, making them ideal for hanging baskets and window boxes.
Surfinia: A trailing variety perfect for cascading arrangements.
Wave: An innovative hybrid characterised by its spreading growth habit, great for ground cover.
Growing Conditions
Light: Petunias thrive in full sun, requiring at least 6 hours of sunlight daily.
Soil: Use well-draining soil enriched with organic matter. A slightly acidic to neutral pH (6.0 to 7.0) is ideal.
Watering: Water consistently but avoid waterlogging. Allow the soil to dry slightly between waterings.
Temperature: Prefer warm temperatures, ideally between 15°C and 25°C.
Care and Maintenance
Fertilisation: Feed with a balanced, water-soluble fertiliser every 4 to 6 weeks during the growing season to promote vigorous growth.
Pruning: Deadheading spent flowers encourages continuous blooming. Trim back leggy growth for a bushier appearance.
Pest Management: Monitor for pests such as aphids and spider mites. Use insecticidal soap or neem oil as necessary.

Bouquets: Their rich colours add a lively touch to mixed bouquets.
Centrepieces: Combine with foliage and complementary flowers for striking table arrangements.
Wreaths: Use dried or preserved petunias in floral wreaths for a rustic charm.
