Asian Greens Slide Show, Crops in our Hoophouse

I’ve started my year of monthly posts about Asian greens with one about senposai and at the Mother Earth News Fair in Vermont this past weekend, I presented my slide show on Asian Greens, which is here for those who missed it. Click the diagonal arrow symbol to get the full screen version.

Today, back on the farm, I spent the morning in the hoophouse. I harvested 4 buckets of cucumbers from one 90′ bed of Spacemaster bush cucumbers. We harvested 2 buckets two days ago, and today they have really taken off!

I also harvested 3 gallons of green beans – we planted Strike, a very upright variety. We find that bush beans tend to sprawl in the hoophouse, and the varieties that do well for us outside (Provider and Bush Blue Lake, from Fedco Seeds), grow straggly inside and the beans curve. It’s probably because the shadecloth on the hoophouse is too dark for beans.

The Gentry yellow squash are doing very well. I’ll harvest those tomorrow (we’re alternating cucumber and squash harvest days currently)

The other crops in our hoophouse now are peppers (we’ve had a handful of green bells). two beds of tomatoes that have been struggling with aphids and sooty mold, and some Iron and Clay cowpeas as cover crops. See this sad picture of the aphids and sooty mold:

Aphids excrete a sweet liquid called honeydew. In warm moist conditions this sugary substance grows a black mold on every deposit. This is called sooty mold. We have been dealing with it by jet-washing some of the tomatoes every sunny day, and we are winning. The photo above was specially chosen to demonstrate the problem – it’s not a crop to be proud of at this point! We use a brass jet-spray nozzle on a hose and wash them in the middle of the day, so the leaves can dry quickly – we don’t want any more fungal tomato diseases moving in!

Starting with what’s being harvested now – squash and zucchini are coming in nicely. The hoophouse Gentry yellow squash (chosen for being fast-maturing) is coming in by the bucketload, and the outdoor yellow squash and zucchini have started producing.


I’m off to Burlington, Vermont this weekend, for the Mother Earth News Fair. I’m giving two workshops:

Cold-hardy Winter Vegetables,on Saturday 6/10 at 11 am on the Yanmar Sustainability Stage, immediately followed by book-signing at the Mother Earth News Bookstore noon- 12.30.

Producing Asian Greens on Sunday  6/11 at 3.30 pm on the Heirloom Gardener Stage.

I’m also doing demonstrations of tomato string-weaving at the New Society Publishers booth 2611, near the Mother Earth News Stage (not the Bookstore this time), at 10 – 10.30 am and 3-3.30 pm on Saturday and 10 -10.30 am, 11- 11.30 am and 2- 2.30 pm on Sunday. Check out my Events page to see the pink sparkly tinsel tomato plant models I use!


At the Heritage Harvest Festival near Charlottesville, Virginia, on Friday September 8 (the Premium Workshops before the main Festival), I’m presenting on Growing Sweet Potatoes at 3.30-4.30 in classroom 7, followed by book-signing at the Monticello Bookshop.


The June/July summer issue of Growing for Market magazine is out, and includes my article on Hoophouse soil salt buildup. This is an issue we have been dealing with – we see white deposits on the soil. I did a lot of research and found ways to water the salts back down deep in the soil profile. I also gathered information on how to measure and monitor salinity, and how to understand the test results and their different testing methods and different units of measure. I learned about salt tolerance of different crops, the plant symptoms of excess salinity, and how to prevent the problem in future. This topic is rising in importance as more people use hoophouses with drip irrigation systems. We were blithely ignorant for our first several years of hoophopuse use, as salinity takes a few years to really develop, and there wasn’t much information available.

I’m also looking forward to reading the other articles, especially Summer lettuce lessons from Southern growers by Jesse Frost. There are some great photos of beds covered with hoops and shade-cloth, which show a good system. I always appreciate articles written for southern growers, which can be in short supply.

Daisy Fair in Utah’s zone 5 has written about moveable tunnels with in-ground hydronic heat. So there’s information for cold climates too. Sam Hitchcock Tilton has an article with tips learned from Dutch and Swiss farmers. Robert Hadad advises on careful monitoring of costs of production in order to actually make a living from farming. The flower growing article in this issue is from Debra Prinzing and is about American Flowers Week, a chance to highlight American-grown flowers with some light-hearted fun photos.


The May/June Organic Broadcaster just arrived in its paper format – I’ve had the digital one for a while. Good thing I’ve got that long car ride to Vermont this weekend to catch up on my farming reading!

The front page story this time is about Kansas farmers, Tim and Michael Raile, transitioning thousands of dryland (non-irrigated) acres to Organic steadily over the next 5 or 6 years. Dryland farming focuses on moisture retention. The Railes grow a wheat/corn/
sunflower/milo (grain sorghum)/fallow rotation. They are also trialing some ancient grains.

Organic production in the US is not meeting demand, and organic imports are increasing, including organic soy and feed corn, not just bananas and coffee. More farmers want to produce Organic poultry, eggs, milk and meat. And so they are looking for Organic feed at an affordable price. This is often imported, which raises issues about how Organic Standards vary from one country to another, and the bigger issue of sustainability – not always the same as Organic! Does it really make sense to ship in grains to feed livestock?

Harriet Behar writes about the true meaning of Organic and overall methods of production. It’s not just about following rules on allowed inputs and materials – it’s a whole approach to how we treat the soil, our plants and livestock.

Hannah Philips and Brad Heins share research on how cover crop choices can influence the fatty acids and meat of dairy steers. Jody Padgham writes about CSAs responding to competition and decreasing membership by offering more options on shares and delivery. Gone are the days of “One box, one day, one price” CSAs. Numerous modifications of the basic CSA model have sprung up to better fit the diverse needs of customers (members). Kristen McPhee writes about the Vermont Herb Growers  Cooperative, which buys from various small-scale growers and aggregates orders to larger buyers. Other topics covered include lessons learned from Hawaii’s GMO controversy, paying for end-of-life care without losing your farm, and many short items and classified ads. As always, a newspaper packed with information.


And by the way, we’re also picking blueberries – ah! heaven!
