When to plant Begonia Tubers

The best time to plant begonia tubers in the UK is in early spring, typically from March to April, once the risk of frost has passed. Start the tubers indoors in pots or trays filled with moist, free-draining compost. Place them in a warm, bright location, such as a windowsill or greenhouse, to encourage sprouting. Once the shoots are around 2–3 cm (1 inch) tall and the weather is consistently warm, usually by late May to early June, you can transplant them outdoors. Begonias thrive in mild conditions and should be protected from late frosts.

How to Plant Begonia Tubers

To plant begonia tubers, start indoors in early spring (March to April). Fill pots or trays with moist, well-draining compost and place the tubers with the concave side (hollow side) facing upwards. Cover lightly with compost, ensuring the top of the tuber is just below the surface, and water gently. Position the pots in a warm, bright location, such as a windowsill or greenhouse, but avoid direct sunlight.

Once the shoots are 2–3 cm (1 inch) tall and the risk of frost has passed, usually in late May to early June, transplant the begonias outdoors or into larger pots. Choose a shaded or partially sunny spot with rich, well-draining soil. Space the tubers 15–20 cm (6–8 inches) apart and water regularly to keep the soil evenly moist. Add mulch to retain moisture and suppress weeds.

How long do Begonia Tubers take to grow

Begonia tubers typically take 4 to 6 weeks to sprout after planting, depending on the temperature and growing conditions. Once planted in early spring, they will develop shoots and can be transplanted outdoors after the last frost, usually in late May to early June. From planting to full bloom, begonias generally take around 12 to 14 weeks, with flowers appearing in early summer and continuing until autumn if cared for properly.

Why Grow Begonia Tubers?

Growing begonia tubers is an excellent choice for gardeners due to their long-lasting and vibrant blooms, which add stunning colour to gardens, patios, and containers from early summer to autumn. They are highly versatile and thrive in a variety of conditions, including shaded or partially sunny spots, making them perfect for areas where other flowers might struggle. Begonias are available in a wide range of colours, shapes, and sizes, allowing you to create a personalised display. Additionally, they are low-maintenance, requiring only regular watering and occasional feeding. As tuberous plants, they can be lifted and stored over winter, providing a cost-effective way to enjoy beautiful flowers year after year.

Where can you grow Begonia Tubers?

Begonia tubers can be grown in a variety of locations, making them a versatile choice for gardeners. They thrive in flower beds, borders, containers, and hanging baskets, adding vibrant colour to any outdoor space. Begonias prefer shaded or partially sunny spots, making them ideal for areas with limited direct sunlight, such as north-facing gardens or under trees. They also do well in patios, balconies, and window boxes, as long as they are protected from harsh sunlight and strong winds. With proper care, begonia tubers can brighten up both small and large spaces throughout the growing season.
