We’re in northwestern Missouri (zone 5), and we are preparing our barrels today (April 24) for planting in the next couple of days. Most info for our area says to plant them in early to mid May, so we’re a tad bit earlier than necessary… but the good seed potatoes around here are going fast! If you need info about when to plant for your area, it’s probably best to call and ask a local plant nursery, or a company that sells seed potatoes, when the best time to plant potatoes is for your zone. Many times, seed potatoes are only available shortly before and during the right time for planting.

For those asking about the sawdust, as far as I can tell it doesn’t have to be “rotted” (it will rot as you go). Most lumberyards will give you plenty for free–just be sure to call ahead; I’ve found that some places charge a small fee for it, while the place down the road might just be happy to have you take it off their hands! Just don’t use it for mulch; it does rot or “sour” and it’s NOT pretty. Works great for potatoes in a barrel, though!
