I think I read somewhere, that if you do not want to attract carrot fly when thinning out,then you should snip the seedlings , rather than pulling them. Is this true, as I have not yet purchased a fleece to cover them. Do people get a successful crop without fleece?
I sow thinly in 6 inch wide rows, then don't have to thin the seedlings. I also grow them between rows of onions, the smell of which may confuse/deter carrot fly. No fleece is used. There is usually a small amount of carrot fly damage, but nothing significant. No-one nearby seems to grow veg, so that may be the largest factor as folk who grow in allotments seem to suffer the most. If I were in that position, I would use fleece.
It's said that thinning - or, for that matter, harvesting - very late in the day or even after dark can avoid attracting carrot fly.
