Sweet potato harvest

From planting back in mid-June, it’s been 3-1/2 months to the sweet potato harvest. The variety, Beauregard, is listed as 80-100 days to maturity, although, like potatoes, you can dig them up anytime, as soon as the tubers have formed. The vines are frost-sensitive, and the tubers shouldn’t be left in the ground if the tops are frost-killed, so I’ve been gambling with the first frost timing in order to let them grow for as long as possible. Today seemed like a good time to start. This has indeed been a really easy, pest- and disease-free crop, requiring only a little weeding until the vines filled in. Harvesting turned out to be equally easy. After digging up a few plants to see how the tubers grow, Lynn, Toshiko and I set up a quick hand-harvesting system: remove the vine, loosen the soil with a digging fork, scrabble around for the taters.

The soil had quite a lot of moisture from recent rains, so we had to spend a little extra time brushing off clumps of clayey earth. We left them for a couple of hours to dry in the breeze, then collected them in bins and brought them into the Milkhouse. By the book, sweet potatoes could use 10-14 days of curing at 80-85°F (25-28°C) . In part, this allows some of the starch to convert to sugar, making them…sweeter. That sort of HEAT isn’t available around here right now, but for this first time around, and too small a quantity for really long-term storage, I’m not too concerned. I baked some a couple of days ago, and they already taste good. Let’s see what a week or two indoors does for ’em!

Sweet potatoes!

Sweet potatoes are in! They were a last minute addition this year, I was expecting them by the end of May, and then started to write ’em off when I couldn’t get in touch with the grower who was supplying them. But he came through, and they arrived by UPS yesterday, one box with around 1000 slips. Bob P., the sweet potato farmer who sent them, is also here in Ontario, but further south in a microclimate zone near Lake Ontario that’s a lot warmer. Still, they should grow here as well. The variety is Beauregard and they’re started from slips, which are vine cuttings. This is the first crop I’ve started strictly from direct grower-to-grower info, it was great to chat about them on the phone, rather than do the usual new crop…research. And they sound unbelievably trouble-free. Bob’s instructions: stick ’em in the ground with the growing point 2-3″ (5-7.5cm) above the surface, 12″ (30cm) in-row spacing, and as little as 12″ between row, all the way up to 3′ or whatever you like for tractor transplanting and cultivation. That’s it! No watering in, no watering except in extreme drought conditions. Just…weed. Hmmm… I’ll look into them more, but for now, that’s what I did, and there they are. The leaves will probably die off, it’s new rooting that should happen. One mild concern: sweet potato grows best in loose, sandy soil, where here the heavier clay loam is being well-compressed by lots and lots of at times pounding rain. Also, the slips are apparently supposed to be planted within 7 days of cutting, and it’s about a day after that. We’ll see. In 100 days, sweet potatoes? ;)
