I first grew my own garlic a few years ago, and had mixed success (mainly due to the position of the garlic I think). For the last two winters I’ve not really had the motivation to do much in the garden, but this year I’ve decided to try growing some garlic in a wooden trough I have that my Dad made earlier in the year for me to grow french beans in. It’s nothing massive, about 8-10 inches deep (16-20 cm) a foot long and half a foot wide (30cm by 15cm, roughly). I’ve planted about 6 cloves so hopefully that’ll give me 6 bulbs of garlic next June/July.
If you want to try growing your own then whilst it is a little bit later than the ideal time, you can still get them planted, but do it as soon as possible! Ideally you should buy specific garlic for growing from your local garden centre, but you can use normal garlic cloves, however the results may not produce large sized bulbs, but it’s still a good way to try it.
You need to plant them about half a foot to a foot apart (although I cheated, but we’ll see how they fare) and about an inch under the surface. You don’t need to ‘unwrap’ the clove, just make sure the pointed end is pointing upwards. Then you can just leave them until about the end of June or early July.
I’ll keep you updated on how mine go 
One little fact, the colder the winter, the stronger the growing garlic will be!
