Thanks for the advice all I tried my best to do the trapezoidal cut...it was very snug so I am pretty happy with what I ended up with for a first attempt.
I used gift wrapping ribbon to tie the donor branch in, if anyone is going to try approach grafting don't use it. It breaks under the pressure. I then used a cable tie over the top to get it really tight.
I also added a bit of sphagnum to the soil surface to increase the humidity around the graft, I guess it won't hurt?
Sorry for the poor phone pics, but if anyone has any advice on better technique or if I did something that could be improved on let me know for next time.
Also, would anyone have picked a different 'front', I thought the roots were best on this side but would like to hear other opinions?
