I have not found a barrier works much. Used to grow them surrounded by
a wooden box structure 2 scaffold boards high and that didn't stop
them. Then we grew in an old large water tank with sides nearly 3 ft
above ground and they still got the carrots. This year only one carrot
has shown any sign of root fly so I think it must have been something
else that has done the job, possibly last winter or the dry spring.
Welcome though.


Looks like I have been celebrating success a bit premeturely if carrot fly
have had a bad year and nobody seems to have any damage.
Been battling the fly for a few years now and this year is my first
worthwhile harvest.
