American Persimmon Dormancy Requirements
I started a boat load of 90 chromosome American persimmons from seed this summer in rootmaker cells. These are for wildlife and most will be planted directly from the cells into the field this fall. Eventually they will be used as rootstook for bark grafting specific varieties.
However, I want to try my hand at bench grafting so I transplanted about 45 of them into 1 gallon Rootbuilder II pots. I plan to overwinter these and attempt to bench graft them next spring.
My concern is size. Some may not be large enough for bench grafting by the appropriate time next spring if I let nature take its course.
I'm considering letting them go dormant naturally outside, but bringing them inside and giving them a head-start growing under lights. I'm hoping this will let them bulk up a bit before grafting time.
Does anyone know how much dormancy (Chill hours or something) they require before I wake them up?
