So I've been growing potatoes in my garden for quite a few years. After reading Michael Pollen's book, Botany of Desire
, I almost feel obligated to do it, in spite of the fact that there's not a lot of ROI in the endeavor. And because they're so cheap, I don't know a lot of other people who do it, and thus find something of a void of information about the practice. This year, I came across something new. Not all, but quite a few of my potatoes had dark patches that seeped a dark red fluid. Here's a pic
So I did some poking around and I don't find any obvious diseases. There's nothing I could find below the surface of the skin so if it's an infestation, they are microscopic organisms. I suspect some form of fusarium, but that's just what I'm getting from the Google. Anyone else ever come across this?
Worth noting, these are clones from commercial potatoes. In spring, about when it's time to put potatoes in the ground, any you have in the house exposed to natural light cycles will start to bud in the eyes are perfect for cutting up and throwing in the ground. So that's what I do typically and did this year. The varieties were your run of the mill russet and white potato. This infection seemed to affect the russets more than the whites, but both seemed afflicted, but only about 30% of the harvest for the russets, maybe 10% of the whites. Do you know what caused this?
Other possibly relevant factors—the myth of global warming seems to have expedited this years harvest of almost everything. Things seem more mature this year at this point than they have in the past. We had a pretty early last frost, about three weeks before typical. Also, the potatoes grew next to garlic and some of the plants were likely volunteers from last years crop.
