This is probably being a bit over protective, but with icy cold weather and snow predicted, I made some D-I-Y cloches out of old milk bottles the other night to protect my radish seedlings. I also put some newspaper down on the newly sown seed. Now my veg patch looks more like a rubbish tip, but it's better to be safe than sorry and I can probably reuse the cloches for starting other seeds.
