Last year I planted some garlic cloves. They weren't bought to grow, they were just ones from the kitchen which had started to sprout. They are supposed to be ready to harvest once the stalks have started to dry. I noticed that they had dried and withered this morning so I decided to harvest them.
The bulbs seem a little small and only seem to consist of a couple of small cloves each.
Apparently the best time to plant garlic is the autumn, so I'll be giving it another go later in the year.
