companion planting

I have a drum I’ve started growing potatoes in. I will gradually fill the drum over time so the potato stems short more roots and make more potatoes as the drum fills. I have one end of an arch coming out of the drum. I want to plant something with the potatoes to grow along the arch. I guess it...

G'day, I have had some of my potatoes (kipflers) have these yellow insects on them... they don't look like aphids .. .kinda like little yellow trilobites ... They don't appear to be interested in the Radishes in the same bed that I am growing in. Are there any good companion plants/...
