Damage to Leeks

[JohnParticipant]

Hi Charles

Many but not all of my leeks have been damaged but I can’t see and sign of caterpillars. I have not had any problems before so have not netted. Are they likely to recover? Is it better to dig them out or cut them at ground level and then cover with enviromesh hoping for new growth? First photo shows undamaged leeks.

Ah shucks John, you have entered the world of leek moths, horrible pests whose caterpillars start tiny, in the heart leaves, and you rarely see them.
It’s why I mesh most of my leeks from planting until about 10th September when the moths stop laying/caterpillars stop eating and they pupate for winter.
I would try cutting some and leaving others, see which works best.

Thank you Charles. The good news is that there is no onion white rot on this plot – small mercies!
