I once read of a guy taking a razor to his tomato plant where he wanted to take a clone from(just scratches). Then take a lump of seeding soil in burlap(potato bag) and tie this around the wound and keep it wet. Roots would develop there.Then he can cut and plant. Does this work. There were no mention of rooting hormones.
Yes it does work, It's called air layering. Just gotta keep the burlap moist and cut and plant as soon as you see roots.
