Air layer healded over

[Hailun]

I did an air layer on a bougainvillea over a year ago, it has breached the layer. Wondering if I can do it again in the same place, any tips please

Yep, you can do it again in the same place.
I don't have specific layering experience with Bougies, but in generic terms make sure the area you cut away is wide enough to avoid any bridging (1 - 1.5 times the diameter of the trunk/branch you are layering) and it is really important to completely scrape away the cambium (the layer directly under the outer bark), again to avoid bridging. You can also do things like apply a wire tightly just under the top edge of the layering cut-out which seems to help with succesful layering, particularly if the species being done is prone to callousing which can impede root growth while the layer is developing. Not sure if this applies with Bougies.
If you're lucky RayM (or some other more experienced person) may chime in with some extra bits of info!

Hi Hailun,
Yes, you would be able to do the layer again. You will need to make a new cut around the top cut, maybe 2-3mm higher, to make sure there is new tissue showing. The bottom cut needs to be about 1.5 times the diameter of the trunk. It is most critical to make sure that you scrap off all the Cambium. Scrap down to the hard wood, you won't hurt the the hard wood. Bind a wire around the hard wood and push this hard up against the top cut. Paint the top cut with hormone. Use a 50/50 mix of Clonex Purple and Yates Cutting Powder. You need to soak the Sphagnum Moss in Seasol for at least a half hour before use. When adding the Sphagnum Moss make sure the water is squeezed out very well. Be very generous with the amount of Moss surrounding the layer.

Thank you so much will have another go at it
