The October issue of Growing for Market is out, including my article about heirloom tomatoes. It’s an assessment of tomato varieties we have grown, mostly in our hoophouse, and how they’ve done in central Virginia. When we decide to try a new variety, we first grow just two plants, in our hoophouse with all the other weird and wonderful types we like, and a bed of early-maturing varieties like Stupice and Glacier. We also grow non-heirlooms, including hybrids like Sun Gold. We track whether we like the flavor, how productive they are and how disease-resistant they are.
Some of the winners for us are Amy’s Sugar Gem, Black Cherry, Five Star
Grape F1, Garden Peach, Jubilee, Mountain Magic F1, Reisentraube, and for simple delicious reds, Tropic. We love Cherokee Purple and Striped German, but they *appear* not to be very productive. I suspect browsers got them all!
This GfM also includes practical help with financial reports from farmer Chris Blanchard, a consideration of copper-based fungicides and their bad effect on soil health, from Meredith Melendez,an Agricultural and Resource Management Agent for Rutgers Cooperative Extension. Organic farmers need to take more mindful care when using copper compounds, even when facing Late Blight. Alexandra Amonette writes from Washington state about dealing with the extreme heat this summer, and Gretel Adams encourages flower farmers to hang in there producing hardy cuts for the last part of the year.
If you are considering a different support system for your long rows of tomatoes next year, give string weaving a go!
I heard my book Sustainable Market Farming got a great review in Acres USA although I haven’t seen a copy yet.
We’re in the transitional period in our hoophouse, planting the winter crops. Today is Yukina Savoy transplanting and tatsoi thinning day. As an aid for future winter hoophouse planning I’ve been working on a chart of soil temperatures for best germination of vegetables, and how many days it takes for germination of each vegetable at different temperatures. This chart is a work in progress, so if you have any gems of information to contribute, do leave a comment. For instance, if you firm up any of the uncertainties, or if your experience contradicts what’s written here, I’d love to know! Click to open the pdf.
And a blog I’ve just signed-up for is from the same Chris Blanchard who writes for Growing for Market. It’s the Purple Pitchfork or the Flying Rutabaga (the weekly newsletter). Packed with info on farming, based on real experience, from someone who is paying close attention.
