Allium Leaf Miner

After having had a few good leeks in a lamb casserole a couple of weeks ago I was disappointed that the main crop were looking a bit weedy. They weren't getting fat and started to show bumps and breaks in the stem. So I checked them over - yes the dreaded Allium Leaf Miner again.

For pictures and advice see the RHS site >>

We haven't grown onions or leeks for 3 years to try to clear the soil of pupae but they seem to be endemic now. I planted a second batch of leeks in a different part of the garden and covered them with a fleece tunnel during August & early September when the adult moth is supposed to fly. So far they look OK (need a bit of weeding though).

Leeks - plus chickweed & leaves!
