Non-Stop Begonias, scientifically known as Begonia tuberhybrida, are a widely favored choice among gardeners for their ability to produce continuous blooms. Grown from tubers, they offer a diverse palette of vibrant colors, including red, pink, orange, yellow, and white. Their compact growth (12-18 inches tall) allows versatile use in containers, hanging baskets, and garden beds, providing consistent color throughout the growing season.
Planting and Environmental Needs
These begonias prefer bright, indirect light or partial shade, making them suitable for locations that receive morning sun or late afternoon sun, while being protected from intense midday sun which can scorch their leaves. If planted in too much shade, their flower stalks may become leggy as they stretch for light.
The soil for Non-Stop Begonias should be well-draining, rich in organic matter, and slightly acidic, with a pH range of 5.5 to 6.0. Good drainage is important as these plants do not tolerate soggy conditions, which can lead to root issues.
Routine Care Practices
Consistent moisture is important for Non-Stop Begonias, but overwatering should be avoided. The soil should be kept evenly moist, allowing the top inch or two to dry slightly between waterings. This practice helps prevent waterlogging, which can cause stem rot.
Regular fertilization supports continuous blooming. A balanced liquid fertilizer can be applied fortnightly during the growing season to encourage healthy growth and abundant flowers. Adequate feeding promotes flower production. Ideal temperatures for these plants are around 75 degrees Fahrenheit during the day and 55-60 degrees Fahrenheit at night, though they can tolerate higher temperatures if shielded from direct sun.
Pruning and Deadheading
Pruning and deadheading are beneficial practices for Non-Stop Begonias to maintain plant health and encourage more blooms. Deadheading involves removing spent flowers, which prevents the plant from expending energy on seed production and redirects it towards producing new flowers. Removing faded blooms contributes to a tidier appearance and can help prevent insect infestations or soil-borne diseases.
Light pruning can also be performed to shape the plant and improve air circulation, which is beneficial for overall plant health. This can involve removing any yellowed or dead leaves, or thinning out areas that appear overcrowded. Such maintenance promotes continued flowering and helps the plant maintain its compact, bushy form.
Overwintering Non-Stop Begonias
Non-Stop Begonias are often grown as annuals in cooler climates, but their tubers can be overwintered to enjoy the plants for multiple seasons. Before the first frost, usually in autumn, the tubers should be lifted from the soil. After lifting, allow the tubers to dry for several days, then gently remove any remaining soil and dried foliage.
Store the tubers in a cool, dry, and frost-free location, typically between 45 to 55 degrees Fahrenheit, packed in materials such as peat moss or sand. Occasional light watering of the storage medium can prevent the tubers from completely drying out. In spring, approximately 4-6 weeks before the last expected frost, the tubers can be brought out and started indoors to give them a head start before planting outdoors.
Troubleshooting Common Issues
Yellowing leaves often indicate issues with watering, either too much or too little, or a nutrient deficiency. Overwatering is a common cause of stem rot, which appears as soft, decaying stems.
Stunted growth can point to insufficient nutrients or the presence of pests. Common pests include aphids and mealybugs, which can hinder growth and overall plant vigor.
Fungal diseases like powdery mildew and stem rot can also affect these plants, especially in conditions with poor air circulation or excessive moisture. Addressing these issues typically involves adjusting watering practices, ensuring proper fertilization, and inspecting plants regularly for early signs of pests or disease.
