My harvested garlic is starting to rot in storage. I've done everything by the book. From planting to harvesting to drying to storing it. Slowly it seems to be rotting from the inside to the outside. Turning almost to a powder. Looks fine from the outside until you touch it, then you realize something is wrong. Got the seed garlic from my neighbour who has been successfully growing garlic for years. He has no problem with his. Worried about 'white rot' but it doesn't seem to present like it. There was no indication of a problem when it was in the ground. All looked perfect when first harvested. Worried about planting now for next years crop. Can anyone help me diagnose the problem?also, should I perhaps not plant this years garlic in the same location? Thank you!
