A Florist's Guide to Gardenia
Gardenia, renowned for its rich fragrance and waxy white blooms, is a beloved choice among florists. With its elegant appearance and captivating scent, it has become a staple in floral arrangements and gardens alike.
Botanical Characteristics
Scientific Name: Gardenia jasminoides
Family: Rubiaceae
Native to: Southeast Asia, particularly in tropical and subtropical regions.
Growing Conditions
Light: Prefers bright, indirect sunlight. Avoid direct sunlight as it can scorch the leaves.
Soil: Thrives in well-draining, acidic soil (pH between 5.0 and 6.0). A mix of potting soil and peat moss works well.
Watering: Keep the soil consistently moist but not waterlogged. Water when the top inch of soil feels dry.
Humidity: Requires high humidity, ideally around 50-70%. Consider misting or using a humidity tray.
Maintenance
Fertilising: Feed with a balanced, water-soluble fertiliser every month during the growing season (spring and summer), and reduce feeding in autumn and winter.
Pruning: Lightly prune after flowering to maintain shape and encourage bushier growth. Remove any dead or yellowing leaves.
Pest Control: Watch for common pests like aphids, mealybugs, and spider mites. Treat infestations with insecticidal soap or neem oil.
Seasonal Considerations
Flowering: Typically blooms from late spring to early summer. Some varieties may produce sporadic blooms throughout the year.
Winter Care: Protect gardenias from frost if planted outdoors. If grown indoors, keep in a warm location away from draughts.

Bridal bouquets
