nurture tuberous begonias
Tuberous begonias are some of the showiest summer flowers, and they make ideal pot plants. The large male flowers look like full-blown roses with a less flamboyant female attendant on each side. They do best in bright semi-shade in places that aren’t too hot – think shadehouses or verandahs. Climate is important, too. The plants will languish if temperatures reach much above 30°C or the atmosphere is very humid. Let the plants get quite dry between watering, watch out for snails and slugs, and liquid-fertilise every couple of weeks. In autumn, when the leaves die down, compost the plant, or save the tubers and store them in a cool, dark, dry location ready for spring planting.
