Onion Fly

Yesterday walking around a friends garden, I noticed a shallow box on stilts, I'm informed that the way to beat Carrot Fly is to grow them at least 30 ins above the ground, as they fly under that height.

I seem to remember being told a good trick is to surround the Carrots with a fine mesh screen of that height so that they fly over the top.

Anybody know which is true?

Both are. It is true the flies rarely fly more than a few inches off the ground (they are poor fliers).

The mesh isn't to make them fly higher. Just to keep them off the carrots. They won't fly high enough to get over the top.

Many thanks Catso, I will give it a try next year.
