Here is how: be lazy. Be lazy enough to let some potatoes get wrinkly, moldy and send up half a dozen shoots. Aw shucks, so much for mashed potatoes for dinner. Toss it in the compost instead. Waste a few bucks, why not? Now ignore your compost. Don't remember to cover it when its raining for months. Don't remember to water it when its hot and dry, and definitely don't bother turning it. By spring you may just find that your favorite disgusting spud is thriving and well. Out of guilt for letting it rot in your cupboard in the first place, you stick it in an unused corner of the veggie garden to give it a pitiful chance at life.
I know we weren't even planning on growing potatoes. Just look what happens when we buy them! It got watered by the sprinkler on a timer along with the rest of the garden; our exalted lettuces, high-demand herbs and medicinal calendulas. It got ignored. We have made it to August now and enough is enough. No more goodwill; the tomatoes need light and air and that potato is using up space, out with it! Wait a minute....1....2....3..4.5.6789...10...no. more?! 27 potatoes were in there. From one plant. A major portion of four to six meals for our family. I have got to be lazy more often!
Well I hope you weren't expecting a how-to list or a motivator with altruistic reasoning to 'be part of the solution.' Don't get me wrong, I am a big supporter of all that. Life just gets busy and full and composting properly isn't one of my highest priorities. Let's just say I have my own reasons for composting, even if I am a bit cheeky for 27 of them being potatoes.
