The boy and I were due to sow some radishes, turnips & peas in the polytunnel tomorrow, so I went down tonight and built a heavy duty cloche on the bed were going to use tonight by torchlight. The night temps are now around 2c higher than outside, so I'm hoping the extra layer will give any sowings a good chance of survival. Really put the brakes on any other sowings though until we're clearer about the longer pattern of the weather.
