Yesterday I gave my three hour presentation “Providing for the Full Eating Season” to the Local Food Hub in Charlottesville,VA. I’d guess there were 50 people there, and 11 of them bought copies of my book!

A question came up that I don’t know the answer to, and now it has me curious. Do leave a comment if you have an answer. Some professional growers need to know how to allow for the slowing rate of crop maturity going into winter, when deciding how much of a crop to grow. Because we at Twin Oaks don’t sell our food, we can simply provide a transition from warm (or cool) weather crops to cold weather crops, without worrying exactly on the quantity of each. Those selling at farmers’ markets or CSAs could possibly do similarly. But those selling wholesale need a certain amount of a crop – either a box or no box – but not half a box. Naturally, all growers need to look at what is worthwhile.

I think in our gardens we have simply made our decisions based on experience, without a numerical base. I can say that 7 x 4 x 90ft of kale will provide 10 gallons of leaves at least three times a week in November, December, February, March. Not January maybe. I’ve never actually counted. And five outdoor beds of spinach (each 4 rows X 90ft) under thick rowcover, combined with about 700 row feet in the hoophouse will be plenty for 100 people for the winter. And we can eat more than 700 leeks per month from October to February. But’s that’s about all I know. Per person, that’s about 25 feet of kale, 20 feet of spinach and maybe 20 feet of leeks for winter in Virginia.

In my last post I said we’d had an overnight low of 10F, but in reality it only dropped to 14F. We were lucky with the last winter storm. We didn’t get snow, only got a thinnish build up of ice from freezing rain, and din’t lose power except for 15 minutes on Monday, presumably due to our supplier switching off while reconnecting those who had lost power. Now it looks like we’re in for more cold winter-storm weather.

I have in the past uploaded my slideshow presentations to SlideShare.net, but they closed down my account saying I was guilty of “violating SlideShare’s Terms of Service and/or Community Guidelines.” I can’t imagine what I can have done wrong, so I’ve appealed. The wheels of progress grind slowly. Meanwhile you can find my June 2013 presentation on Planning Fall Crops at Virginia State University; my Growing Great Garlic presentation at CFSA, uploaded by Fred Broadbent. VABF has my Crop Rotations for Vegetables and Cover Crops presentation.

If anyone knows other ways I can upload slideshows, please speak up.

What a week! With the forecast for low temperatures on Sunday and Monday nights this past week, we back-pedaled on our transplanting plans. The tomato plants in our coldframe were very tall. In order to cover them we extended the cold-frame height by balancing plastic crates on top of the blockwork walls. Setting the lids on top of this construction was a bit precarious, but it worked well. Only a few of the taller tomatoes got nipped at the very top on Monday night when the temperature plummeted to 30F. 5/14 is very late for a last frost for us. Our average for the past ten years is 4/30, but in 2009 it was 5/19. In 2011 it was 4/14. Farming is full of surprises!

On Tuesday we started transplanting tomatoes. Hot dry windy weather. On Wednesday 5/15 it reached 90F. On Thursday afternoon we planned to continue the big transplanting of our Roma paste tomatoes. Three rows are in mowed no-till rye, vetch and winter peas cover crop and one row is on black biodegradable plastic mulch. (Here’s an interesting link to a comparison of the two biggest brands of biodegradable plastic mulch. http://extension.udel.edu/ag/files/2012/03/2012DegradableMulchWM.pdf) But Thursday’s shift was inauspicious. We started with only 5 of us (we plan for 7). One person had to leave at 4pm. One person was called away to bale hay. Another person agreed to provide childcare for the person baling hay, from 4-6pm. Then another person started to feel ill, and left the scene. The 3 of us still working at 3pm started to sow our second zucchini and summer squash. We each used two dowels to make holes every 6″ in the biodegradable plastic mulch. We got the holes popped through, but then another community member cycled by and warned us of a strong thunderstorm heading right for us. Discretion being the better part of valor, we retired for a tea-break and to consult the local radar on Wunderground. An intense “red and yellow” storm, not very wide (ie not very long-lasting), was due any minute. Once it started to rain we decided to quit trying to garden for the day. good thing too. We got an inch of rain in an hour. Too bad the soil hadn’t dried out enough for us to do a second hilling of the potatoes before this new rain. or make ridges for sweet potatoes. Now we’ll have to wait another week, during which there is 20-80% chance of some rain every day except Monday, when it is forecast to be foggy. So I’m getting closer to finishing reading my library book. . .

April 2013 Growing for Market

April 2013 Growing for Market

Meanwhile, in the Mental Gardening Department, I found I had made mistakes in my Growing for Market articles on parsnips and fennel, about which plants can cross-pollinate each other. So I wrote an apology and correction. One of these mistakes is in my book. In case you are reading my former, deluded, beliefs, here is the correction: On parsnips, the facts are that parsnips can cross with wild parsnip, but not with carrots or Queen Anne’s Lace, as I wrongly claimed.

On fennel, the facts are that fennel does not cross with anything except other fennel. It is widely said (even by some seed companies!) that dill and fennel cross, and some even describe the terrible flavor of the resulting crosses. Clearly this is a superstitious belief that continues because acting on the belief produces good fennel (or dill) seed. Similar to how someone might snap their fingers to keep away tigers – no tigers – complete success! I’ve long believed dill and fennel crossed. It’s good to know I don’t need to worry about that any more.

This is the first error I’ve found in my book. Soon New Society wants a list of corrections from me, for when they do a reprint. I’ve only found this and one formatting glitch so far. Embarrassing, but I repeat my Mantra for Consolation: “The only people who never make mistakes are those who don’t do anything.” On Monday I did an interview for Lightly on the Ground Radio on wrir.org (Richmond Independent Radio) with Sunny Gardener. I’m learning how to find and download the podcast (so many technical skills to learn!) I’m working on a powerpoint presentation on Planning Fall Vegetable Production, for Virginia State University’s Summer Vegetable and Berry Field Day on June 27 at Randolph Farm. This will lead nicely to my Last Chance Sowings article for the August Growing for Market and a Cold-Hardy Winter Vegetables presentation for the Mother Earth News Fair in September
