How to plant double begonia bulbs

Planting double begonia bulbs is easy and rewarding, providing you with months of vibrant blooms. Follow these simple steps to ensure success:

Choose the right location: Double begonias thrive in partial shade, making them perfect for spots that get morning sun and afternoon shade. They can also be planted in containers for flexibility in placement.

Prepare the soil: Begonias prefer well-drained, rich soil. If planting in garden beds, work in compost or organic matter to improve fertility and drainage. For containers, use a high-quality potting mix.

Planting depth and spacing: Plant the corms with the concave side facing up, about 2.5–5 cm (1–2 inches) deep. Space them 15–20 cm (6–8 inches) apart to allow room for growth and airflow between plants.

Water lightly after planting: Water the bulbs gently after planting to settle the soil. Double begonias prefer moist but not waterlogged conditions, so water regularly while ensuring the soil drains well.

Fertilise for more blooms: Once the plants begin to grow, feed them every two weeks with a balanced, water-soluble fertiliser to encourage healthy foliage and abundant flowers.

With these straightforward steps, your double begonia bulbs will thrive, rewarding you with stunning, full blooms that last from summer through to the first frosts. Perfect for borders or containers, they’ll bring long-lasting beauty to your garden.
