Pathetic Carrots

[Marb67]

Aaaaaaaand again years and years on I can't get a single carrot harvest after healthy sowing in a seed tray transplanted to the soil. Thin, wispy nothingness. So far I gave tried growing in 3 different gardens with the same results. And no, there was no carrot fly.

I give up

Probably too close to other plants or not enough light. I notice what looks like raspberries in the background there. Those things' roots get everywhere.
I used to try and grow carrots in little patches of soil in semi-shade like you are doing, and never had any luck. Since I started growing them in rows in open ground in full sun, they do far better.
