I finally got to plant out my celery today. I don't know if its too late, but I planted the seed in February as recommended, so not much I could do about that. The seedlings grew Reeeaalllly slowly...not sure if this is normal or if I did something wrong. According to Kay Baxter, growing celery is easy. If its not growing well, it means its either too wet, too dry, or not getting enough nutrients.
The seedlings are 10-15cm tall, so we'll see if they grow in time to count as a winter vegetable.
I also noticed that the parsley is growing back. Apparently picking all the caterpillars off worked and I guess its too cold for them now.
The swedes are growing a lot of leaves but no signs of bulbs yet.
Wheat is growing well...looks like grass :) I'm growing this as a carbon crop.
