I noticed some of my hard neck garlic leaves dying/turning yellow too early so I dug up one bulb. I found that it was infested with what I believe to be root nematodes. They had eaten through the outer layers causing brown decay and it looked like a nest of them in the stem. I checked a neighboring bulb and found some beginning to eat the outer layers of that one too.
My garlic still needs about a month before harvest. I'm afraid that if I leave them in the ground all my bulbs will be destroyed. However, if I harvest this early, I won't be able to cure the garlic for storage. Should I go ahead and dig it all up now, or wait until the skin and cloves have properly formed and simply hope that not all the garlic will have been affected?
