    Default Brassica collars

    Just watched Monti Don on Gardeners World plant brassicas.
    No mention of brassica collars.
    I note that none of my gardening books mention them.
    When I was young and had an allotment I grew rows of nice cabbages and caulis, only to see some wilt in the sun. The plants were infected with cabbage root fly maggots which nibbled off the roots.
    An old timer at the time suggested brassica collars, I have used these since and never had a problem (touch wood).
    My collars are scooge ones. I cut a compost bag into 6 inch squares. Each is a collar. Fold in half and half again. Snip off the centre point, not very much. Open out and you will have a hole in the middle. Cut a slit from the side to the hole. Fit round your brassica black side up. Weigh down with 6 or so small stones. Job done.
    Anyone eles use them?
    Thanks Jimmy.

    I never bother because I just net all my brassicas, anyway. Keeps everything away.

    Heard of them. Never used them. Didn't realise you could make them from compost bags . I think I might give it a go. Because from what you've described of the cabbage root fly, I'm having issues with them this year. Never experienced them before.
    Thank you.

    That's why I've never used them tight as a ducks butt

    I only used them the once, I was a bit to rough and decapitated some of my Kale.

    I use 4"(approx) squares of carpet underlay with a cut in the centre of one side into the middle of the square and then slid around the stem of the plant. The idea is that the fly lays its eggs on the underlay where they soon dessicate instead of on the soil where they would be kept moist, hatch into maggots and burrow into the plant stem . It works for me .

    I have tried using the commercially produced felt disks but I find they are too hard and cause damage to the plant stem with the same effect as damage by maggots

    I have bought some in the past, but made one today out of a bit of old linoleum.
    Our England is a garden, and such gardens are not made
    By singing-'Oh how beautiful!" and sitting in the shade,
    While better men than we go out and start their working lives
    At grubbing weeds from gravel paths with broken dinner-knives. ~ Rudyard Kipling
