practice graft in the polytunnel using a grafting block
Once I'd got the hang of the intricacies of the cuts, the practice grafts were relatively easy as they're done at bench height using offcuts from apple trees pushed into a grafting block to simulate the rootstock. It is quite a delicate operation though because the most natural way of holding each 'twig' while you're cutting it always seem to be with your non-cutting hand in direct firing line of the blade should it slip...
And later it was time for the assessment, where we had to complete 3 grafts onto planted rootstock in 20 minutes. Being at ground level is a bit more difficult than bench level - you can either bend right over to work close to the ground (not great once you're over 35, to be honest) or kneel on a grafting block (a bit tough on the knees but bearable for 5 mins at a time). We each had a line of 3 rootstocks and a choice of scion - I decided on Blenheim Orange. I finished my grafts well within the 20 minutes, fully labelled and trimmed to an appropriate height. Suburban Orchard here we come!
