Plant begonia tubers now ready to early cuttings in spring, says AG garden writer Michelle
Fill a seed tray with light, sandy, loam-based compost. Or mix horticultural sand with multi-purpose compost. Adding leaf mould to the mixture will give the tubers perfect growing conditions.
Space the tubers in the tray, hollow-side up, about 2in (5cm) apart so they are not touching each other and about 1in (2.5cm) into the soil. Make sure they are not too deeply planted in the compost.
Water the soil carefully so the tubers are not soaked, keep the soil moist but not waterlogged. Place the tubers in a propagator or in a warm spot indoors at about 13-16°C (55-61°F) in good light.
