To date I have sown around 6 maybe 7 sowing of carrot seed. BUT I have yet to grow any carrots!!! I have sown early and late variety (Tendersnax and Autumn king) as I have done for the past 9 years on the allotment. No problems in the past but this year as soon as the seeds have germinated to around 1/2 inc tall they suddenly disappear? All sowings have been covered in enviromesh from the start and no soil disturbance present. Different brands of seeds used in different locations as I have two plots on two different sites (about 4 mile from each other). Other plot holders also having similar issues in germinating the carrot seed. Even now the weather and soil are very warm the problem still exists.
