I hot callused with a reptile heat lamp!
I bench grafted peaches/nects to American Plum (1 year old bare root) with simple splice grafts. I bundled all 6 of them together and bagged the roots with moist sawdust/paper. I put them in cold storage with the infrared lamp almost directly on the graft. I used an old dimmer switch to adjust the graft temp to 80ºF. I periodically checked the roots over the 3 week period to make sure they were still wet. The buds near the graft (and lamp) did sprout, but it didn’t do any harm.
Unfortunately, I lost picture of the setup. There wasn’t anything remarkable about it anyway. I think I will wire up some simple carbon film resistors for heat source next time. The heat lamp was overkill. I only used it because it was quick.
Here is current pic of Fantasia on Prunus Americana.
