Tuberous begonias are a group of Begonia cultivars, sometimes regarded as some of the most spectacular of the genus. One of the first hybrids produced was B. x sedenii in 1870, a cross between B. boliviensis, collected by botanist Richard Pearce and a species from the Andes.


When grown indoors, the Tuberhybrida should be exposed to bright indirect light.


When grown outdoors, tuberous begonias are shade-loving plants, they also require a bit of morning or late afternoon sunlight. A location in dappled or filtered light also works well, but the plants won't survive midday sun or heat. Begonias need moist, well-drained soil and are likely to rot in soggy conditions.


When planted inside, keep the soil evenly moist, allowing it to dry only slightly between waterings. Reduce water in winter (stop watering tuberous begonias in autumn). Always avoid wet or waterlogged soil.


When planted in flowerbeds, begonias require about an inch of water per week to thrive. One or two light rainfalls per week are usually more than enough to provide that amount. If there is a need to water, water in the early morning.


When plant is in full growth, fertilize with balanced liquid fertilizer at half strength at alternate waterings.


Disease problems associated with Begonias include Botrytis blight and stem rot, powdery mildew, and Pythium root and stem rot. The major pests of begonias are mealy bugs, spider mites, thrips, scales, snails, and slugs. Begonias may be sensitive to insecticidal soaps.


The most toxic parts of Begonias are underground, it's still best to keep Begonias out of reach of your pets if they like to nibble on your plants.
