They're still coming up clean as a whistle, with no fly damage at all, and the best news is that there are more to come! They seem to be really liking the soil conditions in that bed, which is filled mainly with home-made compost to which I added lots of sand. I obviously got the soil texture right, because none of the carrots have forked, and their skins are practically blemish-free.
You can appreciate them better when they are washed:
They are quite "stocky" - short and fat - which makes this variety very suitable for growing in raised beds, since these often don't have a huge depth of soil.
The thing which has made the most difference for me this time is the Enviromesh with which these carrots have been covered. It has kept the Carrot Root Fly out completely. There is no damage at all. My only reservation about the mesh is that it does cut down the amount of air and light that the plants beneath it get, which might be a problem sometimes.
Not this time though. I'm really happy with these!
