The November/December issue of Growing for Market is out, and
with it my article on No-Till Cover Crops. We use an organic no-till winter cover crop mix of winter rye, Austrian winter peas and hairy vetch before our paste tomatoes (our home-grown Roma Virginia Select available from Southern Exposure Seed Exchange). We sow the cover crops in mid-September (zone 7 here, average first frost Oct 14). In early May the vetch is starting to flower and the rye shedding pollen, and we are itching to transplant our paste tomatoes. We mow down the cover crops with our hay cutting machine, which cuts closer than a bush-hog and leaves the straw in long strands. Then we set out stakes and ropes and transplant, pushing aside the cover crop as needed. The vetch provides all the extra nutrients the tomatoes need, and the resulting mulch keeps the weeds away for 8-10 weeks. By then we have installed T-posts and started string weaving.
We mow between the rows if there is much regrowth from the cover crop, or weeds getting big, then we roll out spoiled hay to deter weeds for the rest of the season, add some more organic matter and keep the cooler temperatures and the moisture in the soil over the high summer. We plan for this and make our rows 5.5ft apart, so we can unroll the big round bales to carpet the aisles.
In my article I talk about the pros and cons of no-till, and give examples of other suitable food crops and other suitable cover crops for no-till.
Also in this issue is an article about the honeybee crisis and what we can do, such as growing pollinator habitat and encouraging or importing other pollinators. A follow-up article discusses the big problem of neonicotinoid insecticides, which are very long-lasting and may even cause more insect deaths the year following spraying. This is a major problem for organic farmers and for everyone who eats vegetables and fruits. Yes, all of us.
There is also a timely article on preparing hoophouses to deal with snow-loading,and one on growing lisianthus for splendid cut flower sales.
Chris Blanchard tackles flaws in the proposed produce safety rules, which seem in places to be based on a nonsensical idea of growing food in a sterile environment. The comment period for the Proposed Produce Rule and the Preventive Controls Rule closes on November 15. If you read this before that date, click here for information and instructions on how to comment on the rules. Chris (who has written a series of very practical recent GfM articles on food safety) also writes in this issue about water (for irrigation and for washing produce) from a food safety point of view. Those who use any surface water (ponds, creeks) have a particular responsibility to check their water supplies frequently and work to keep them sanitary.
I have been writing an article for the January issue of Growing for Market, so that I can take a break at the end of the year. I am writing about Planning Your Harvest Schedule, and I’m including links here to our Twin Oaks Harvest Calendar, which lists which vegetables we expect to have when (if all goes well!). We have the list sorted alphabetically by crop, and also by starting date.
You can see what you could be eating if you lived at Twin Oaks and helped us grow it all. Actually, of course, you wouldn’t have to work in the garden yourself, to get this good food. We share all our work, and you could instead be doing some tasks I’d hate to do, like repairing cars, making tofu or tackling accounting.
