I keep mine under a tree (good light but no direct sun) for about 8 weeks -- until I see the grafted bud starting to grow. Once the grafted bud is beginning to pop out I know the graft has taken and I begin to move it to more sun, gradually. I also let the rootstock (fortuniana in my case) continue to grow until I have a first leaf set on the graft, and then I cut the fortuniana top growth off just above the chip bud.

Thanks Kathy, mine is fortuniana too.
