Did you know that nearly all the supermarket “organic” tomatoes are not grown in soil drawing the nutrients they need from the complex array in the soil, but in an inert material (rockwool, coir or plastic pipes with holes in), receiving as nutrients only what the growers provide in a solution that passes by the roots?

Did you know that your understanding of “organic” might be different from USDA’s? Driscoll’s Berries has over a thousand acres of “organic” hydroponic production in hoophouses in California and Mexico. They are the biggest hydroponic “organic” producer in the world.

Did you know that hydroponics is large-scale? Melody Meyers of UNFI testified at the National Organic Standards Board (NOSB) that her company’s hydroponic “organic” sales exceeded $50,000,000. (Wholesale value – double it to get the retail value.)

Dave Chapman said

One of the challenges of the USDA takeover of organic certification has been the loss of involvement on the part of the organic farmers. As we have all struggled to make a living in a tough arena, it has been easy to give into a sense of helplessness around maintaining strong standards. At the same time that organic farmers have retreated from the process, the USDA has been profoundly influenced by large corporate farming interests.

Three quarters of US hydroponics sales go to only three or four farms – this is a huge concentration of money, power, and influence in a very few hands. And the industry is engaging in heavy lobbying, not just at NOSB, but throughout the United States Department of Agriculture (USDA).

How did this happen? How did “organic farming” change so drastically in six years? My report is based on Dave Chapman’s in his blog Keep the Soil in Organic.

In 2010, the NOSB recommended saying no to hydroponics receiving Organic Certification by a 14:1 vote, in keeping with international standards, the federal law (the Organic Foods Production Act, OFPA) that created the National Organic Program (NOP), and the traditional practices of organic farmers.

At the NOSB meeting in fall 2016, despite hydroponics industry lobbying, there was not enough support to vote to overturn the 2010 recommendation and allow hydroponics, aquaponics and bioponics. (This would have needed a 2/3 majority). Also, the proposal (from the Crops Subcommittee) that would have eliminated hydroponics in organic was sent back for reconsideration. The stalemate means that the NOP will continue to certify “organic” hydroponic operations.

Dave Chapman reported that

Food Democracy Now! presented a petition with over 12,000 signatures to reject hydroponics. Cornucopia Institute presented 1400 proxy letters from farmers and eaters demanding that soil stewardship be a requirement for organic certification. Clearly, the people numbers were on the side of the soil.

National Organic Program (NOP)  director Miles McEvoy stated at the meeting that even if the recommendation allowing hydroponics was defeated, it would not affect NOP policy. The NOP continues to support certifying hydroponics as USDA Organic even though the OFPA law requires Organic farming be based on maintaining and improving soil fertility. The NOP support of hydroponics is also in direct opposition to the 2010 NOSB recommendation, as well as standards in most other countries. Across the world, hydroponic operations are being USDA Organic certified.

A resolution  passed 12 to 0 reading, “It is the consensus of the NOSB to prohibit hydroponic systems that have an entirely water-based substrate.” (This refers to “plastic pipe” hydroponics as opposed to rockwool and coir which are imagined to provide something more than physical support.) This resolution does show consensus in rejecting the idea that hydroponic growing can become organic simply by “adding biology” to plain water, and provides a small glimmer of sanity and common sense. NOSB refused to acknowledge that actual hydroponic farming is not limited to plants that grow in water, but includes those propped up by rockwool and coir. The current hydroponics industry move is to avoid the “H word” and talk about “containerized ” plants – ones held in a small amount of material, but still being fertilized by solutions flowing by.

What makes a system hydroponic is how the fertility is delivered to the plant, not the material that the roots sit in. In a hydroponic system, the fertility is supplied to the plant in the irrigation water. There are so-called “organic” fertilizers that are extremely processed organic materials. For example, the 16-0-0 hydrolyzed soy protein being used in hydroponics acts like a synthetic nitrogen fertilizer. It has little similarity to unprocessed soy meal. In a genuinely organic system, the fertility results from the  complex soil food web interacting with organic materials we growers supply.

The companies speaking in support of hydroponics to the NOSB include Miracle Gro (chemical fertilizer company), Nature Gro (major supplier of substrates for conventional growers), the Organic Trade Association (lobbyists for the big hydroponic “organic” growers), Nature Sweet tomatoes (1400 acres of conventional greenhouses), Houweling’s Tomatoes (250 acres of conventional greenhouse tomatoes), and Driscoll’s (already mentioned).

These companies all want  to get in on the “Organic” market without doing the honest hard work. The food industry spends more money lobbying Capitol Hill each year than the defense industry does!

Know your farmer! Buy local, from trusted growers. Do what you can to speak up for real food, grown in the soil.

I wrote about our winter lettuce (a summary of blog posts here) for Mother Earth News Organic Gardening blog. You can read it here.

peerj-04-1582-g005Margaret Roach at A Way to Garden has had some interesting blog posts recently. One is about a recent study called “Arthropods of the Great Indoors: Characterizing Diversity Inside Urban and Suburban Homes,” and its lead author is Dr. Matthew Bertone. We are hosting an average of over 90 different arthropod types per home! I’ve noticed that we’ve accidentally brought camel crickets from our root cellar into our bathroom! I’ve been reducing their numbers. . .  They don’t appear to be in top 12 found in most people’s homes according to this article.

This post on Do Home Remedies for Weeds or Garden Pests Work? is a careful look at the options often recommended by others, with cautions about pouring lots of Epsom salts, vinegar, clove oil on your plants and soil.

Her Special Weed Issue has links to a lot of useful weed topics, as well as info on a  Baby Birds book with delightful-looking watercolors.

Lettuce in September, Bean borers,

September is a month of change, when it comes to lettuce. We sow and transplant a lot of lettuce. The September 1 sowing is number 34 in our annual series, which runs to number 46 on September 27.

When to sow to eat lettuce in September

In September we are normally eating lettuce which we sowed from late June to mid-July. That’s a tough time for growing lettuce here, and this year was tougher than usual. We got fine seedlings up, but then they were mowed down by cutworms lurking under the shadecloth. We started new sowings in flats, up off the ground on a frame. We tried sowing baby lettuce mix to feed us during the gap. Although we sowed it in a cooler spell, it didn’t come up. We just resowed on 9/16. Now we are having a deluge – of rain, not of lettuce!

Sowing lettuce in September

From September 1-21 we sow head lettuce every 2 days. This is because the rate of growth will slow down when the weather cools, and the harvest dates of those sowings will spread out. They will all feed us through to the spring, if we protect them from cold temperatures. Before we got our hoophouse, we grew lettuce outdoors through the winter under double rowcover. It did stay alive, but we couldn’t harvest very often. Rowcover will provide a temperature gain of 4–6 degrees F (2.2–3.3 degrees C), depending on the thickness. It also reduces light transmission and airflow, but the trade-off can be very worthwhile. Lettuce can survive an occasional dip to 10°F (–12°C) with good rowcover outdoors — but not 8°F (–13°C), as I’ve seen! Adolescent lettuce are more cold-hardy than full-sized plants.

Sowings in the first week of September are for planting in cold frames in central Virginia. These days we have switched to growing spinach all winter in our cold frames, rather than continue these lettuce plantings. We get better value from spinach. It grows faster than the outdoor (rowcovered) spinach, but slower than our hoophouse spinach.This means that after the last sowing for transplanting outdoors, on August 29, we get a short break on lettuce sowing.

We resume with number 38 on September 9. The sowings from 9/9 to 9/17 will be transplanted in our greenhouse. We also sow on 9/15 and 9/24 to transplant into our hoophouse. The sowings from 9/19-9/27 are “insurance plantings” in case something goes wrong with an earlier [planting, or we don’t get the greenhouse beds refilled with compost soon enough, and want smaller plants.

Lettuce varieties to plant in September.

From September 1-7, (the coldframe ones we used to grow), we use cold-hardy varieties Green Forest, Hyper Red Wave, Merlot, Midnight Ruffles, New Red Fire, Oscarde, Panisse, Pablo, Red Salad Bowl, Salad Bowl, Winter Marvel (a Bibb) and Winter Wonderland (Romaine). Pablo is a hold-over from the summer Batavian lettuces. (Heat-tolerant varieties also tolerate cold.) There are also specialized cold-hardy varieties that do not tolerate heat (because they have a relatively low water content). Sow these in fall and winter only.

The salad bowls do fine in the greenhouse and the hoophouse, although I remember they are not cold-hardy enough for growing outdoors here. During the winter we will be harvesting lettuce by the leaf, rather than cutting heads. Green Forest, Kalura and Winter Wonderland are romaines that do well in the winter for us. Note that we don’t grow butterhead lettuce (bibbs) after the end of August.

Once we reach September 8, we are sowing lettuce for planting in the (unheated) greenhouse. We use Green Forest, Hyper Red Wave, Kalura, Merlot, Midnight Ruffles, New Red Fire, Oscarde, Panisse, Red Salad Bowl, Red Tinged Winter, Revolution, Salad Bowl, Tango and Winter Wonderland.

For the hoophouse winter lettuce, we sow Osborne multileaf lettuce types (Multigreen 57, Multired 4, Multired 54), Green Forest, Hyper Red Wave, Merlot, Oscarde, Panisse, Red Tinged Winter, Revolution, Tango, Red Salad Bowl, Outredgeous, Salad Bowl, Winter Wonderland Romaine. For the second sowing on 9/24, we use Include all the same ones except Oscarde, which has given us trouble in the past when started that late.

Small and medium-sized plants of Marvel of Four Seasons, Rouge d’Hiver, Winter Density, and Tango can take 15F (-9.5C). I’ve seen some small unprotected lettuces survive down to 5F (-15C) – Winter Marvel, Tango, North Pole, Green Forest. Other particularly cold-hardy lettuce varieties include Brune d’Hiver, Cocarde, Esmeralda (a bibb),  Lollo Rossa, North Pole (bibb), Outredgeous, Rossimo, Sunfire and Vulcan.

I’ll address winter lettuce in some future post.

Bean Borers

I enjoy Charley Eiseman’s blog Bug Tracks, even though I’m nowhere near in his league of paying attention to insects. It’s inspiring to read his posts! This week he wrote about Gray Hairstreak caterpillars as bean borers.
