Controlled pollination<\/h4>\n

To maximise your chances of success, you will need to pollinate your begonia by hand. Take a male flower whose stamens* are slightly withered (a sign of maturity) and apply them (with a gentle, subtle back-and-forth movement) to the pistil* of freshly opened female flowers. If pollination has worked, a few days later the petals will drop and the pistils will turn brown. The fruit will gradually turn green and swell, then slowly dry out.<\/p>\n

Harvest<\/h4>\n

The ripe fruit of a begonia is usually a dry, dehiscent* capsule* (loculicidal* capsule). However, some species (notably African epiphytes* and Asian shrub-like begonias) produce a fleshy fruit, or even a berry. Fruits are harvested on the plant when ripe. After harvesting, you will need to collect the seeds inside the fruits. For example, use a small tea strainer held over a sheet of white paper: the seeds fall onto the paper, while the fruit debris stays in the strainer.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>\t\t\t\t\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>\n\t\t

Packaging and storage<\/h4>\n

The seeds should now be put in an airtight container (small plastic tube, small stamp bag\u2026). They should then be stored somewhere cool and dark \u2013 a small fridge is perfect. Kept this way, they will last for several years.<\/p>\n

Sowing<\/h4>\n

Sow in a seed tray, on a mix for young plants (light and low in nutrients \u2013 for example, light peat mixed with a little river sand). The seeds are placed gently on the surface of the pre-moistened substrate. Beforehand, mix a small quantity of seeds with a larger quantity of river sand, so you can better see how the seeds are spread over the tray.<\/p>\n

Then place the tray in the dark, somewhere fairly warm (20 to 25\u00b0C) with high humidity*. Depending on the species, the seeds will germinate more or less quickly (from a few days to several weeks). If the seedlings are too dense, thin them out, i.e. remove the surplus seedlings to give the rest more space.<\/p>\n

Pricking out<\/h4>\n

When the seedlings are well enough developed (cotyledons + 2 leaves), they need to be pricked out individually. This is the most delicate step, as some seedlings are barely a centimetre tall.<\/p>\n\n\t\t<\/div>\n\t<\/div>\n<\/div><\/div><\/div>\t\t\t\t\t\t\t<\/div>\n\t\t\t\n\t\t<\/div>","protected":false},"excerpt":{"rendered":"F\u00e9condation contr\u00f4l\u00e9e Pour maximiser vos chances de r\u00e9ussite, vous devrez polliniser manuellement votre b\u00e9gonia.
