You're right - some of these grafts will put on some very vigorous growth,
and while a bark graft gives a lot of cambium contact on multiple surfaces,
it's not very strong for the first year or two, so is subject to 'blowing
out' when a stiff catches the leaves or when a bird lights(perches) on it.
Probably the simplest thing is to take a nice little bamboo stake and shove
it down into the soil next to the rootstock stem - on the 'backside' of the
stem, away from your graft, take a couple of wraps around stake & rootstock
with masking tape just to secure the two together, then, as the scion
pushes out growth, train it in an upright fashion by taping it to the
bamboo stake - this will help promote upright growth - some of mine, that I
didn't stake , have a pretty noticeable 'dog-leg' in them, as a result - as
well as protecting against 'blow-out'.
Ideally, your stake should extend at least a couple of feet above the level
of the graft - with a well-established rootstock plant, your graft may
grow that much or more in the first year - but sometimes less.
I don't always get around to staking in a timely manner, and I've been
pretty dismayed to walk out and find a nice vigorously-growing graft lying
shriveled or crispy & blackened on the ground.
