There I was explaining to my brother, he who is a little older and wiser than I, that I’d devised this ‘foolproof’ method to keep the dreaded carrot fly off my crop on my plot.

I’d built a carrot wall. Not made of carrots but of little planks of wood, so that the carrots cannot get at my crop. A mini raised bed where the carrots can thrive in peace and would, therefore,  crop beautifully and without a blemish.

There was a brief silence from him then ” they might get over the wall by flying, they are after all called carrot flies”.

Here’s my answer:

This is the first time that I have been able to grow carrots without the little beasts getting at my crop. They might fly but they can’t get over my wall!

My sweet peas, on the other hand, needed no walls.
