I just thought I update you on how my ‘potatoes grown in straw‘ experiment is going.

Right now, my Red Norland potatoes that I planted on May 19th are just beginning to bloom. That would be eight weeks from planting. (This, by the way, is a crucial time to keep your potatoes regularly watered to get large, scab-free potatoes – read more about that in this article.)

One cool thing about this style of growing potatoes is that you can easily check on the progress of the tubers forming underground (or rather, understraw). I was curious to know just how big my little potatoes were at this point, so I carefully pulled away the straw at the base of the plant. And lo, and behold…

There it was. A tiny little potato not much bigger than a large pea.

So I learned/confirmed a few things today.

#1. Flowers on plants = formation of little spuds

#2. Potatoes grown in straw are going to be wonderfully clean

#3. I won’t be eating baby potatoes for at least a couple of weeks.

This year I tried something new. I had heard rumors of other people doing it, but I didn’t know of anyone around here trying it.
So this spring, when I planted my potatoes, I didn’t plant them. Instead, I just dropped ’em on the ground in a somewhat straight row. No digging. No shovel involvement whatsoever. Kinda like this…

Then, after I had them all layed out, I covered them all with about eight inches of straw, like this…

Then I waited. And waited. And now, about a month later, they look like this…

So what do I hope to gain by growing potatoes in straw like this? Well, two things actually.

#1. Less weeding

Thus far in the month that the potatoes and the weeds have had to grow, I’ve only had to pull out about five thistles that have popped through. These have been extra easy to remove because the root goes through the straw and is easily pulled out. Plus, no prickles under the straw either.

#2. Bigger Yield

Last year when I regularly watered my potatoes from the time they flowered until the end, I got the biggest potatoes I had ever grown. So the theory goes, if the potatoes are mulched, the soil won’t dry out nearly as fast. Thus even if I don’t water regularly, my yield will be increased because I won’t lose my water to evaporation. But that part’s still just a theory – I’ll have the proof one way or the other this fall. So stay tuned!

And lest I forget…

#3. Easier Harvest

Rake back the straw, and there are all your plump, CLEAN potatoes – what could be easier?
