Florist Guide to Petunia
Petunias are vibrant, showy flowers that are popular among gardeners and florists alike. Known for their rich colours and variety of forms, they bring a cheerful aesthetic to any arrangement or outdoor space. Originating from South America, these annuals belong to the nightshade family and thrive in warm climates.
Varieties
Grandiflora: Large, trumpet-shaped flowers that create a bold display. They are available in a wide range of colours, including purple, pink, red, and white.
Multiflora: Smaller flowers that form bushier plants. They are more tolerant of adverse weather conditions, making them suitable for mixed plantings and containers.
Calibrachoa: Often referred to as "Million Bells," these tiny flowers resemble petunias but have a more compact growth habit. They are excellent for hanging baskets and window boxes.
Growing Conditions
Light: Petunias prefer full sun, requiring at least 6 hours of direct sunlight each day to flourish.
Soil: Well-draining soil is essential. A mix that retains some moisture but does not become waterlogged will encourage healthy growth.
Watering: Regular watering is crucial, particularly during dry spells. The soil should be kept consistently moist, but be cautious of overwatering.
Care and Maintenance
Fertilisation: Use a balanced fertiliser every four to six weeks during the growing season to promote vibrant blooms and robust growth.
Pruning: Deadheading spent flowers encourages continual blooming. Regularly trimming back leggy growth will help maintain a bushy shape.
Pest Management: Common pests include aphids and spider mites. Regularly inspect plants and apply organic pest control solutions if necessary.
Seasonal Use
Petunias are most commonly utilised in spring and summer arrangements due to their vibrant colours. They can be paired with other seasonal blooms such as marigolds, zinnias, and lobelias to create striking combinations.
