Avoid sowing to early, seed will germinate badly or not at all. Seedlings will grow very slow and are much more vulnerable to pests and diseases. Always sow on days without wind and just after a bit of rain has fallen.( mist the soil after sowing).
Plant
Begonia tubers in a flat box in a mixture of potting compost and sand. Place the tubers in a 2-3 inch layer and keep them moist and moderate warm (60 -65 degrees), at a sunny location. This will enhance early sprouting and rooting of the tubers, harden the
plants off by the end of April - early May and transplant the
plants around second week of May into
planters or the border. Be careful that a late night frost doesn't damage the tender
plants. If night frost is expected, cover the
plants for the night with an old newspaper.
Begonia plants like a lot of water, feed them regularly with a summer plant fertiliser.
