Garlic... or lack of it!

I've lost my garlic!
Well, OK, not lost, I know exactly where it is, its in the ground still, doing a big fat nothing! I planted it (with Ed's help) in October, giving it plenty of time to put down roots and send up little green pointy leaves... only it hasn't!
I know I've abandoned the allotment a little in the last few months, and last time I was down there before Christmas I do remember thinking that the garlic should surely be up by now, but I'll just give it a little longer... well I have and its still not there! Nothing, not a shoot, not a leaf, nothing! 5 rows of the stuff! NOTHING!

*grump*

I did have a furtle in the ground and found a few cloves, just where I left them, looking about the same as when I planted them. So I know they've  not been eaten, or gone rotten, just done nothing.

Anyway, I've admitted they have failed, I've bought some more, some that's suitable to plant in spring (hopefully we'll have some cold weather to split the bulbs) and I'll try again. I'm not sure if I should be putting it in the same place though, or just give up on that bit and start again somewhere else? Ah I'll have to think about it I guess...
