Garlic going walkabout?

[longers]

In the relatively short time I've been growing garlic I've had to replant quite a few each year.

I've been told it's birds/squirrels/something else pulling them up but don't think it is and to me it looks like they're pushing themselves out using their own roots.

I think I heard a snippet of something along these lines a while back but searching online hasn't been successful.

Am I right to think they're on the move?

Sure it's garlic not triffid you've planted?

I only grow the 'elephant' garlic and plant it 4" deep. The soil on the allotments is heavy, soo it's not a problem I've had.

I've heard of birds pulling onion sets out if you leave the dead stalk on.

I've had onions, garlic and shallots pulled up, probably by birds.
