Grafting alders
It's me again! Asking hard qeustions.
For a rather way-out (but wholly legal!) project I need to graft this year's growth of Alder (Alnus glutinosa) onto last year's growth of the same. This is a difficult tree to graft, but last year I made significant progress by fixing to the graft a 2 K Ohm resistor, fed with 24 volts AC from a transformer (heat output = 0.2 Watts) and wrapping with 3 turns of bubble-wrap which raised the temperature 10°C above ambient and the grafts showed promise. On 1 May in Newcastle, with 1-2 leaves showing at the terminal I tried again. My grafting advisor said that the scions were too small and they dried out and ran out of food before they could take, so I thought I would do something about them drying out and lacking food and 1) Some of them I wetted with Miracle-Gro + Interflora flower food, just to stop them from drying out during handling. 2) Others I wrapped the graft with small, well-washed cotton strips soaked with the above mixture before wrapping with Parafilm and binding with rubber strips. I thought I was doing right, but maybe I was doing wrong! This year I did even worse! Has the use of Flower Food and /or the Miracle-Gro got anything to do with it? I think my grafting technique is probably OK. Any good ideas for next year? My own good idea, try when the catkins appear. End of February. hould I look to other factors?
