Pruning will not make the trunk "nice and sturdy".

You will need to stake the stems to compensate for the poor growth.

Giving the plants plenty of light, less fertilizer and sparse watering, that
is called growing the plant "hard", will encourage more compact growth and
stouter sturdier stems.

Too late for that this year if you need to bring them in for the winter.

nice and sturdy??? bringing all of mine in for the winter, and they
did well, but would like fatter trunks.
appreciate any suggestions.
