The broad beans, planted at the same time as the garlic, have also pushed themselves up and out. I had a beaut crop of BBs last year and I learned a lesson. Once they grew tall, they fell over and it was cold and I didn't feel like going out there and fiddling around to do something about it.
Even though I can be slow learner I am able to learn from my mistakes. So this year I have already put strings up to support them as they grow.
