My first garlic is rubbish. I suspected this might happen as I put it in very late, er, like March, and the best crops are planted in October-November.
If the cloves don’t get a decent blast of cold then they don’t split/multiply into a fat bulb. The ones I planted have hardly fattened up at all. Or split into bulbs.
Still, they are edible, and I’ve got another row which look much healthier.
Note to self: plant garlic in autumn not spring.
