I have spring cuttings that are now 2 feet tall and just producing figs. One tree has 6 figs, will probably be the size of a pencil eraser in a few days.

As they are young, and i've seen it is best to cut them off to direct more energy to tree/root development - i thought maybe i'd take all but one or two off (just to see what happens to them)

When i remove them, should i cut them now when they are tiny? Should i use a sharp knife? Should i get as low to the branch as possible, or leave a nub? I'm concernced about injuring the tree by cutting it. Thanks!
