Any advice on growing rutebagas, artichokes, parsnips, sweet potatos or peanuts in Zone 4.

Because most of those are either roots, tubers or legumes you shouldn’t have much of a problem after your last frost. Check the Old Farmer’s Almanac, they give a very good planting timeline for your area.

But quite honestly, unless you like those vegetables, I wouldn’t take up the space that you could be using to grow things you do like.

Yeah, I am think maybe just parsnips. They are probably pretty good fresh and I know they keep well and are loaded with vitamins.

Get a big green house. The Parsnips might make it outside but the rest I really don’t think they will reach full maturity. They should all have slightly sandy soil. Parsnips are gross anyway, ew.

Sweet potatoes, peanuts and yams will not be happy in zone 4.

There is so many varieties now days. You are probably right. I got to move from this god forsaken glacial remnant of a state despite its great attributes.

@DREW R: do you have one or know someone who does that is cheap and functional?

@Garebo
That is one thing we are going to try and get for my wife thru VA disability. She needs one for a hobby. They are real spendy. We have been doing our own on tarp tent frames with clear plastic.
