Description - Plants with succulent stems, leaves and flowers unisexuate asymmetric, long pedunculate, grouped dichaziu terminal. ♂ flowers usually are obsolete, consisting of 4 petals oval, two of which are shorter, the ♀ consist of 4 petals equal, persistent. The fruit is a capsule wingtriangular in section, with many fine seeds.
Requirements - The ideal temperature for most begonias is 13-29 ͦ C. In warm areas, begonias should not be exposed to direct sun light must be filtered or indirect. In northern regions begonias be overshadowed during spring and summer. Light too powerful or too low can cause pale leaves, poor growth and few flowers. Humidity should be 40-60%. If on the leaves become brown, the leaves and flowers of fall is a consequence of moisture insufieciente. If humidity is too high and appear fugicide bacterial diseases. The land that is slightly acidic pH 5.8-6.8, light, well aerated, well drained, and pumice perlitul are necessary to ensure good drainage.
Management - inflorescences wilted cut.
Propagation - tuberose begonias multiply by cuttings or division of tubers, ifthey are large. Cuttings shall be of basal branches since April, their length should be about 7.10 cm. At first made available in a mixture of half peat, half sand. Successively engaging in the transplanting depending on plant growth.
If tuberuculul divide is greater necasar cutting tubers into chunks so that each of them contain at least one healthy bud, after which the plants.
Begonias rizomatoase multiply by rhizome division. Ideal period is April. Control aibe each portion to a good bud.
Begonias are propagated by root cuttings fasciculated from May to August.
Most begonias can inmultii and by seeds. To sterilize the seeds mixed with sand, place in aluminum foil to ͦ 16-21 C for one hour. The seeds need light and moisture to germinate, so it is better to not be covered by plover and the ship to be covered with plastic or glass to increase humidity.
