(Roots will sprout from these leaf nodes.) Let cuttings dry on a tray for a few days before you plant them. This curing process causes cut ends to callus (form a thin layer of cells).

Tips on reproducing herbs from cuttings
Turns out, harvesting basil is the key to creating that healthy, bountiful little basil bush. Don’t be afraid to cut! When your basil plant has 3 to 5 sets of leaves, cut the top off just above the second set of leaves from the ground. The single stalk will now end here, and two new branches will now bud and grow from the set of leaves you left behind. Every couple of weeks, repeat the process, cutting just above the first or second set of leaves on your newest branches.
