Elatior begonias are hybrids between tuberous begonias and an interesting species called Begonia socotrana from the small island of Socotra, off the Horn of Africa. Because the island gets so hot in summer, this native begonia species becomes dormant during the heat, and grows and flowers well throughout the cooler weather. Their main enemy is frost but, even in relatively cold areas, lower growing begonias can be used as ground cover under shrubs like azaleas and camellias. Pot begonias into a good quality potting mix such as Yates Macroblend. Peter always adds some perlite to lighten the mix.
All begonias enjoy hard pruning.
Loopers and other types of caterpillars, are insect pests that find tender begonia leaves positively irresistible. If you're vigilant, you may be able to catch them before they do too much damage, but synthetic pyrethroids such as Baythroid or Mavrik give effective, low toxic control and have a repellent action that discourages the pests from returning.
