Fibrous - root and tuberous Begonias are propagated by stem or leafage clipping ; however , the summons is easier and more straightforward with unchewable - rootle Begonias .
Within the fibrous - rooted course of instruction it is easier to propagate cane - stemmed varieties by prow cuttings , and semperflorens or wax varieties through foliage cuttings .
Whichever method you prefer , use a sharp pair of secateurs which has been sterilised with chafe alcohol .
When To Propagate Begonia
When to take and propagate begonia cuttings depends on the type you ’re develop :
No matter which method you use , tote up rooting hormone is usually a good idea .
Check out the steps for diffuse each type below .
Propagating Tuberous (Outdoors) Begonia
Tuberous Begonias spring up out of doors in the flat coat or in container can be propagated by stem cuttings taken in April .
Take 10 cm long cuttings of stem with a blackguard ( section of the tuber ) attach .
Place these in a mix of peat - barren compost and guts , and provide bottom heat of 18 - 21 ° C .
Propagating Fibrous Rooted (Outdoors) Begonia
doubly - flowered types ofB. semperflorensare also commonly propagated from stem cutting .
After overwinter the plants in a coolheaded location , in April , take 7.5 - 10 cm long cuttings .
Place in a desirable culture medium , as above , and , again , provide bottom heat of 18 - 21 ° C .
Propagating Fibrous-Rooted & Cane-Stemmed Begonia
Also in April , take 7 - 10 atomic number 96 long fore cuttings of fibrous - stock-still or cane - stemmed Begonias .
These should be put in in a suitable medium as above , and provided with bottom warmth of 18 - 21 ° cytosine .
Propagating Rhizomatous Begonia
If you are develop rhizomatous Begonias indoors , you may need to take longer bow cuttings because you should be sure to let in a leafage node at the base .
sure rhizomatous types , likeB. rexhybrids and cultivars , are also frequently propagate from leaf cuttings , taken in May or June .
Take a fresh matured leaf , cut off the stalk , cut cautiously through major vein , spacing cut around 2.5 atomic number 96 aside .
Place and peg down the leaf onto a come tray of sandy cuttings compost .
Water well and keep at 18 - 24 ° C , with good humidity , to wait for plantlet to form from deletion points .
In addition to the leaf - cutting method , Rex Begonia kind are often broadcast by a specialize method acting .
Select a leaf that has just mature .
From its bottom or lower surface , make a few pocket-sized incisions along the veins , using a disinfected sharp blade .
Place the leaf , low side down , on compost and nail it or put light weights on the leaf so that it stays in blind drunk contact with the territory .
Keep it in hopeful sunlight ( but not under a hot sunshine ) and water it well .
rootlet will emerge from the cuts in the nervure .
While almost all Begonias can be propagated by stem or leaf cut , rhizomatous varieties are also propagated by variance .
Propagating Semi-Tuberous (Indoors) Begonia
Propagating semi - tuberous Begonia from radical thinning is a little more intriguing , though this is the most vulgar method acting employ to obtain these plants for the next year .
After they have flowered , allow the plant to stay by reducing the temperature to 7 ° atomic number 6 and reducing water but not inducing complete drought .
Maintain this rest body politic for around 6 weeks .
After the end of this stop , cut back back to within 15 atomic number 96 of the cornerstone , and raise the temperature to 10 - 13 ° C , to stimulate new growth .
When the new growth is around 5 cm long , take basal cutting of these new shoots and take root them at 18 - 22 ° hundred .
Keep them light shaded until they have rooted well , then gage on .
