Hi strenghtandhonor,
Welcome !
Do you have space ?
Why graft ? Why not root ?
The main advantage with fig trees is that they sucker easy and root "easy" from cuttings... So really no point to look into grafting IMO . Except for the fun of grafting that is .
I would consider grafting for propagating plums, cherries, apples ... As those do not root from cuttings.
But figs ! Just root them ... Now, you just need to find the cuttings :P
As for your trees :
1. If you want to propagate them, then just separate the suckers . Take them with roots.
2. If you want them more tree shaped, tell them ! with your pruning sheers ! I know , I know... It is heart breaking ...
