What variety of crab is it.
Some scions seem allergic to some crabs.
I have had spotty luck grafting on crabs.
I think it is a poor choice for experimentation of varieties.
If yours goes like mine you can not tell how they will do on their own
tree such as M111, M9, M26 or BUD.

Every variety has a different starting time in spring and it varies by
the mother tree, too.

It does not hurt to let them blossom, but letting the fruit grow is
iffy. The weight could break off the scion. You should provide a sling
or some other support if you insist on growing the fruit.

Very common for the weaker ones to die off the first winter.

I use Parafilm M for all my graft wraps. It is the profession wrap.
Available from supply houses and some local societies buy it in
quantities for their members. Most amateurs think it is too expensive
though. A $14 roll will last the average Nafexer a lifetime so in the
big picture it is not too expensive.
You can use the plastic electricians tape but you should slit it
lengthwise after the first season to let it grow in diameter. The
Parafilm deteriorates naturally so I don't have to worry about that.
Some use masking tape, but I prefer the electricians tape as an
I use the half inch wide and do not overstretch it. Overlap about a
quarter inch and just go up one layer.
How are the Huckleberries doing?
They are blooming here and the native bees are polinating them.
Plums and cherries are all through.
Most pears through too.
Half the apples are in full bloom and the later ones are not even budded
