A Florist's Guide to Begonia
Begonias are celebrated for their lush foliage and exquisite blooms, making them a popular choice among both novice and experienced gardeners. With a diverse range of species and hybrids, they are versatile plants that can thrive in a variety of settings. Here’s an essential florist guide to understanding and caring for begonias.
Types of Begonias
Begonia rex: Known for its strikingly patterned leaves, this variety is often used for ornamental purposes. Its foliage exhibits a wide range of colours, from deep greens to vivid purples and silvers.
Begonia semperflorens: Commonly referred to as wax begonia, this type is characterised by its glossy leaves and continuous blooms throughout the year. They are perfect for bedding, borders, and container displays.
Begonia tuberhybrida: Also known as tuberous begonias, these are prized for their large, stunning flowers. They are often grown in hanging baskets or patio containers, providing a vibrant display in the summer.
Begonia maculata: The polka-dot begonia features charming white spots on a dark green background, making it a striking houseplant choice. Its unique appearance is complemented by delicate flowers.
Growing Conditions
Light: Begonias prefer bright, indirect light. Direct sunlight can scorch their leaves, while too little light may hinder flowering.
Temperature: Ideal growing temperatures range between 18°C to 24°C. Protect begonias from cold drafts and sudden temperature fluctuations.
Soil: Well-draining soil is crucial. A mix of potting soil with perlite or sand offers the right balance of moisture retention and drainage.
Watering: Water regularly, allowing the top inch of soil to dry out between watering sessions. Over-watering can lead to root rot, so ensure pots have adequate drainage.
Fertilisation
During the growing season (spring and summer), feed begonias with a balanced, water-soluble fertiliser every 4-6 weeks. Reduce feeding in the autumn and winter months when the plants generally enter a resting phase.
Pruning and Maintenance
Regular pruning helps encourage bushier growth and can prevent overcrowding. Remove any dead or yellowing leaves to maintain overall plant health. If flowering begonias start to fade, deadhead spent blooms to promote further flowering.
Pests and Problems
Keep an eye out for common pests such as aphids, mealybugs, and spider mites. Treat infestations promptly with insecticidal soap or neem oil. Additionally, be cautious of over-watering, which can lead to root rot and fungal diseases.
