Begonias provide lots of colour per plant.

• Begonia Semperflorens is probably the most widely grown begonia and is also called “wax type” because of the waxy look to the leaves. They are grown from seed mostly as bedding plants and annuals and last until frosted.
• The larger flowering Begonia tubers are currently bringing summer to a colourful finish. The tubers can be dried and stored for next year
• The indoor Begonia rex are demonstrating some strange and colourful leaf shapes. These are Rhizomatus types.
• Cane or Angels wing Begonias are a bit out of favour but make a robust house plant.

Growing Begonia as Annuals from Seed

• Begonia seeds are very small, so it is best to mix the seeds with fine sand and sow onto the top of the moist compost.
• Do not cover the seeds with more compost but cover the container with cling film.
• Place the container in a shaded or dark position at 68 – 72F.
• Check the seeds daily for emerging  seedlings, this normally takes about two weeks.
• As soon as the seedlings appear remove the polythene and place the tray in a light position. Seedlings require a great deal of even bright light.
• If the window sill is cold cover the container with a cardboard box at night.
• When the seedlings are large enough to handle  prick them out from the seed tray and pot them on into 3 inch pots.
