>>1033036>Is there any generalizable rule as to which plants can be propagated by cuttings?Some such plants can form the beginnings of roots near their base if they're stressed, or in moist conditions.
If you look at the base of the plant and see a lot of bumps, those are the beginnings of roots. It means the plant is definitely capable of sending roots out of cuttings. Pic related is of a tomato plant with such bumps, as an example.
