This is my wekiwa tangelo tree.  I really like the fruit. It is about 2 1/2 inches where I cut it off, actually my biggest tree at about 12 feed until I cut it.  I'm leaving the limbs below the 3 foot high graft wekiwa.  Rootstock is swingle. The bark grafts are for panzarella giant orange, the one bigger than a grapefruit.

I'd picked the rest around December 1.  Holds very good on the tree.  I'm also going to graft a few limbs of another tree with the panzarella giant lemon.
I wrap the scion in parafilm and wrap the cut off stump with it as well.  I fasten the scion to the trunk with a small nail.  I wrap the trunk as well with vinyl budding tape.
 
Last of all I cover with aluminum foil to prevent sunburn
