lauriel; first off, here's the grafting aftercare info sheet I hand my 'customers' at the HOS Fruit & Berry Cutting (Scion) Exchange
For the time being, I'd let your scions continue to leaf out; from both scion and rootstock. Mine, about a dozen different grafts this year, are doing the same. Isn't it exciting! I've nearly come on the forum to suggest everyone watch for 'nibbling' of any kind on the new scion bud / leaves. If I notice this, I'll smear some Tanglefoot
around the base of the limb / rootstock to stop (after carefully eliminating the nibbler if I see it). Tanglefoot's great stuff for stopping ants, earwigs, and everything else that's small and crawls â€“ here you go: http://www.tanglefoot.com/products/barrier.htm
As the leaves develop from the rootstock
I'd (and this is simply my opinion - other's might say â€˜rub them off nowâ€™) let a nice pair form where ever they'd like, then pinch out
the tip/s, leaving those leaves to help feed / shade the rootstock. But don't let them get past 2 sets
of leaves and compete directly with the scion above.
It's late enough in the season that the green you see is most likely viable leaf from your scion/s. If it dies, it will happen fast; that means (to me) the connection never took and the bud/s were only 'feeding' off the energy stored in the scion.
I hope you check in with progress reports and / or questions.
