It maybe the case that there are two locomotions driving bulbs
deeper-- one of
contractile roots but a second one of action-reaction of leaves
shooting upwards.
And the factor of the soil involved because if a clay soil is
involved contractile roots
may have a tough time of getting deeper.

It is easier to pull a rope than push it.

Never studied physics, eh, Sean. Newton would not be calm when
someone calls one of his laws as pushing a rope rather than pulling.

And funny, because, maybe that is what a biologist thinks of when
reading Newton's law of every action has an equal and opposite
reaction, in that you, Sean thinks of a rope being pushed or pulled.

So definitely, biophysics was not one of your talents, Sean.

It is easier to pull a bulb down into the soil with a contractile root,
than it is to push it down by the weight of leaves. Pulling it will move
it in the direction the force is applied in. Pushing will result in a
reaction in the direction of least resistance, at most, a simple
rotation of the bulb.

There are many physical reactions that take the path of least
resistance, the effect of pushing a rope, if you were to take the
opportunity to attempt the task, will show you all about it.

Besides, Newton's law about equal and opposite reaction is about when
you push on something, that something pushes back on you.
