Q1: What does pot-bound mean?

[Answer]

Plants cannot move about, so wherever a seed falls to the ground, that is where it will grow.

If many seeds fall close together, or you plant your seeds too close together, the plants will grow tall, spindly stems.

Under the surface, roots also compete for nourishment, and none of them will grow well.
