How to grow Rex Begonia

  • Fluorescent

    OR
  • Indoor

  • Medium

Can use African violet potting mix. Enjoys a humidity tray or can be kept in a terrarium to keep the humidity up.
While you plant is growing well, it is a good idea to make some new plants from one of the healthy leaves. Begonias can be made from leaf cuttings, cut the leaf in several places across the veins and place pretty side up in a tray of a mixture of compost and sand or vermiculite. Make sure there is contact between the leaf and the compost, by placing small stones on the leaf. Cover the tray with a plastic bag and keep warm at about 20C. Baby plants form at the cuts. It is also possible to cut the leaves in strips, across the leaf and veins and press end on into the compost.

Try to plant in a location that enjoys artificial lighting / indoor lighting and remember to water moderately. Keep in mind when planting that Rex Begonia is thought of as tender, so remember to wait until your soil is warm and the night time temperature is well above freezing before moving outside.
