The picture should just illustrate that the last salad of the year will soon be sown. To be exact right now on Monday the 10th. - neither more nor less. The date is not chosen at random, but has been the same for several years when it comes to sowing lettuce for use in October-December. According to Elliot Colemann, who grows vegetables all year round in the polytunnel in Maine, the art is that the crop must be almost fully developed when the day length in the autumn is down to 10 hours. Then the green growth stops, and the salad can last for several months as long as there is not too much frost.
At our latitudes, you have to "hit" the date on October 22, and for my favorite autumn varieties Little Gem and Winter Gem, it has fit quite well with sowing on August 10. It was sown in a plug box, planted in a manure bench sometime in September, and lettuce heads can be harvested almost right up until Christmas.
