although I've never used cabbage collars I was looking through a seed catalogue the other day and I though I mite give them a try as its said to protect against cabbage fly keeps the soil moist and weed free

so before buying I though I would ask if anyone uses them and how you rate them

Well, I know they're supposed to horrible if you get them, and that'll probably happen once I say this - but I've never had them on my plants and never used collars

Its impossible to grow Brassicas in my garden without using collars. I have never bought any though, they are easily made out of cardboard or leftover weed fabric.
If you have never had trouble with root fly in the past then I wouldn't bother with them. I have to say that the bit in the catalogue about them keeping the soil moist and weed free is stretching things a bit. They don't tell you that slugs love to hide under them.

thanks all I'm crossing cabbage collards of my shopping list
