As an update, here is the layout of my current garden - the vining and pole plants will be grown up 8' tall trellises - however I'm moreso concerned with my attempt at companion planting and avoiding placing plants that don't like each other near each other.

Especially in terms of fertilization and watering requirements as my available space is _INCREDIBLY_ limited.
