A quiet day this week at the urban farm. The trainees are on holiday and we were all winding down before the Christmas break. If you read the last blog you’ll know that the women folk were out in the cold while the men were keeping warm in a polytunnel. I might be a bit slow on the uptake but I’m not dim - this week I got myself a job planting out onion seedlings in one of the polytunnels while the chaps edged one of the paths to stop weed creep.
The seedlings we planted out are North Holland Blood Red - a mild and sweet variety. If you plant them close together you can thin them in the spring for spring onions and leave one which will fill out for harvesting as a full bulb later in the year. If you want to give them a go sow under cloches in February or direct in the ground from March to April in 1.2cm (½ inch) deep drills, leaving about 25 to 30 cm (10 to 12 inches) between rows. Water very gently if the soil is dry, and cover with soil. The smell of onions confuses carrot fly and Sarah Raven ( http://www.sarahraven.com ) recommends planting them as companion plants to protect your carrots. Or you can wait for spring when they will be appearing in the urban farm veggie boxes.
