Help, i apparently have onion fly in my leeks. Leaves all straggly, and burrowing in the leek . I have been told to dig them up and burn them, dig the ground and spray with jeyes fluid. Is this right???

[savbo]

everything except the jeyes sounds right

Leek moth - Mine have them as well
If you cut the green mothy tops off there is usually still a fair length of usuable leek.
I've been having cheesey leeks this week and making leek and potato soup for freezing.

It seems a shame just to burn them

Agree with both up top, you should be able to salvage something and freeze it. I would never use Jeyes on the soil.
The ones your throwing take away from the plot or burn.

Using Jeyes Fluid is not a choice. It used to be sold as a soil steriliser but it is no longer approved for that. Something to do with phenols it contains.

Cheers for that, ive now found the threads about leek moth, and will follow the advice!!! Looks like fleece over the whole allotment next year!!

Mine have too for the first time, but I am sticking it out as they are still quite small.

Hope that once the chillier weather arrives the leeks might grow a bit more.

If not, I'll be adopting your plan MumofStig
