We had about a half-dozen of these grain bags from the malt Homebrew Husband buys for his beer. The plan was to use them, but it quickly became apparent that we’d need more bags. We supplemented with used burlap sacks. We bought them (10 bags for $5 at Sky Nursery) but I think if you asked around at coffee shops you could score them for free.
We started by rolling the sides of the sacks down and filling the bags with about 6 inches of soil. We weren’t super precise about this. It was pretty late at night already and we were trying to get ‘er done.
We shook everything up really well. I looked like I was shake-and-baking the worlds heaviest chicken during this part. It was quite the workout. When the bone meal was thoroughly blended into the soil, we added between 3 and 6 potatoes to each bag depending on the size of the potato – the fingerlings were smaller.
And covered the potatoes with 2-3 inches of additional soil.
That was it. It was simple, but tiring to fill all those sacks. We used (when I say “we” here, I mean Nick) the wheelbarrow to move all the sacks to a nice sunny patch of lawn we are happy to kill off.
When the potatoes grow I’ll “hill up” the vines inside the sack with loose compost and straw to encourage as much tuber formation as possible. My goal is to get at least 12″ of “hill” material on top of the vines.
I’ll let you know how it works out.
What do you grow in containers, sacks, or grow-bags?
