We got our sweet potatoes all dug and safely indoors before Saturday night’s 27F and Sunday night’s 26F. Whew! Another Garden Year Milestone passed. We got about 223 boxes this year. The boxes contain about 23lbs each, so that’s 5129 lbs, plenty to feed 100 hungry people for six or seven months. Last year we had a huge harvest, and sold some for a Farm-to-School program and gave some to our local Food Bank. Our average harvest for this size patch (about 700 plants) is 4035lbs. This year we got a yield of a little over 7lbs of sweet potatoes per plant. Last year’s record crop was 11lbs per plant.
No sooner had we finished the sweet potato harvest than we put new outer roof plastic on our hoophouse (yesterday). We decided to just replace the outer layer as we thought it must have big holes, as the inflation blower wasn’t keeping the air bubble between the two layers inflated.

We’ve always replaced both layers at once previously, but October is getting late in the year for this job and it’s so much easier to replace just the outer layer! We think we got some holes from a surprise hailstorm (rare here), and we knew we’d made some when we replaced the plastic a couple of years ago. We’d pulled the outer layer too tight, trimmed it, then tried to let out a bit more slack from the margins. The result was lots of holes from the wigglewire’s old positions.
But we didn’t find any huge holes in the old plastic when we got it down, and this morning the house is still not inflated, so our problem is not solved. The next suspect is the inflation blower, which has a theoretically a large enough output, but maybe it’s not working well any more. It sounds OK. Maybe some warmer days will help. . . Not sure of the science there – maybe wishful thinking. We need a well-inflated hoophouse (high tunnel) to provide winter insulation as well as keep the house sturdy in the face of winter weather.
In a couple of days I’m off to Topeka, Kansas, for the October 24-25 Mother Earth News Fair. Here are the details repeated from last week’s post:
I will be giving Fall and Winter Hoophouses as a keynote presentation on Saturday 10-11 am on the Mother Earth news stage and Spring and Summer Hoophouses
on Saturday at 1-2pm on the Organic Gardening Stage. I’ll be signing books at 11 am Saturday in the MEN Bookstore. I’ll be demonstrating How to String Weave Tomatoes using my sparkly-pink-tinsel and pencil model at the New Society booth 2055 on Saturday at 4pm, and Sunday at 10 am and 2 pm.

I’ve been enjoying the Connection bimonthly newsletter from the USA National Phenology Network. They monitor the influence of climate on the phenology of plants, animals, and landscapes. “Phenology is nature’s calendar—when cherry trees bloom, when a robin builds its nest and when leaves turn color in the fall. ” They have a lively newsletter and a participatory project called Nature’s Notebook, where everyday people are encouraged to collect data in back yards, nearby parks or as part of a field study. They have a few other newsletters too, for different audiences.
Margaret Roach, author of the blog A Way to Garden, has a great post about the connections between high numbers of acorns, white-footed mice, and ticks. And acorns, chipmunks, mice and Gypsy moths. And acorns, mice and song birds.
