Today I planted some savoy cabbage plants that I got from the garden center. Their selection isn't great, as they are at the end of their season. I have been looking for Brussels sprouts, but can't find any. They told me they may have some in next week. Am not very hopeful that they will. Also planted out some salad greens - mainly lettuce, which I'm hoping sill grow for the next month and give me some salad!
Beetroot can still be sown, if you can get the plants, to give a crop by Christmas. Also, pak choy and Swiss chard - again if you can get the plants.
