Hey I can not seem to find anything much about doing Coleus Leaf Vein propagation so I have decided to go ahead and test the theory myself and post results as I go for future reference to those whom think they might want some info.
Ok so I am doing this in such a method anyone at home can also do.
There are 2 leaves pinned to a mix of Sphagnum moss and peat moss, sprayed with tap water to keep moist.
The pot is covered with plastic kitchen wrap and a half job plastic wrap tie to keep some sort of environmental control.
Notes:
1. I have used cable ties to pin leaves but you could use Plant ties, a stone or anything that works for your situation.
2. The Sphagnum and peat moss could be substituted for any of your favorite propagation media. I just had it there.
3. The kitchen wrap could be subbed with a prop dome, tray and cloche or anything that allows light through and easy access to respray if needed.
Cheers for now Staffy
Hi Staffy
We look forward to hear how the propagation goes.
I have successfully propagated Begonia using leaf cuttings. With begonia leaves it is important to trim the petiole close to the leaf base and then make 1cm long cuts across the main veins of the leaf at right angles. The leaves are then placed on the soil as you describe. The new plants will grow at the points where the veins have been severed. I would be worth trying a couple of Coleus leaves with severed veins and see if either works best.
Coleus is easily propagated by cuttings, the roots grow quickly and you don't need to use rooting hormone.
