Cultivating Wax Begonias - A Guide to Nurturing Yearly Begonias Annually
Wax begonias, a popular type of annual begonia, are renowned for their ease of growth and continuous blooming from early spring. These bedding plants are a favourite among gardeners, particularly those who grow them as annuals. Most gardeners typically purchase wax begonias in the springtime.
Wax begonias are tender perennials that can overwinter in warm zones with frost-free winters. However, they are often grown as annuals in USDA zones 9 or 10 and above. Their hardiness zones make them ideal for a wide range of gardeners.
These begonias thrive in moderately humus-rich, well-drained moist soils. They prefer bright areas for growth, whether outdoors in shade to partial shade or indoors in sunny locations. It's essential to ensure the soil drains well to avoid potential problems such as powdery mildew, botrytis, and stem rot, which may arise in soil with poor drainage or humid areas without adequate air circulation.
When it comes to planting, start seeds indoors in January or February, or 6-8 weeks before the last spring frost date. The spread of annual begonias ranges from 6-12 inches (15-30 cm), and they typically grow to a height of 6-12 inches (15-30 cm).
Wax begonias are known for their waxy rounded leaves and flowers that come in red, pink, or white. Some popular cultivars include 'Party Pink', which grows pink flowers and bronze leaves, and 'Prelude White', which produces white flowers. Other specialty varieties include 'Emperor Red' and 'Senator Red', which produce red flowers, and 'Whopper Rose Bronze Leaf', which grows large pink flowers and bronze leaves.
Insect pests such as mealybugs, thrips, slugs, and snails may affect wax begonias. However, with proper care and attention, these issues can be managed.
Begonias can be propagated by cuttings or division, in addition to growing from seed. One unique variety is 'Barbara Rogers', a clumping variety of wax begonia that can grow up to 5 feet tall in USDA zones 7-9, featuring white flowers all season long.
