How can I get bigger garlic bulbs?
I've been harvesting garlic this past week. The bulbs look firm and healthy, but once again I'm kind of disappointed. The bulbs are all fairly small, nothing like the size of the ones I see in the grocery store. Some were just fat, single rounds. I have plenty of garlic. Running out certainly won't be a problem. But how can I grow bigger bulbs?
I planted garlic last fall (October-November) in four different beds. Two of the beds are in-ground. One gets morning sun till about noon, then dappled sun all afternoon. The other gets a little less sun.
The other two were raised beds, filled with bagged soil, and get full sun all day. The plants in those beds were definitely bigger and taller. That might have made some difference in the size of the bulbs, but not that much.
I fertilized about every 4-6 weeks with an organic fish emulsion/kelp fertilizer and watered regularly until about a week ago.
Last year, I harvested during the July 4th weekend. This year, the plants started flopping over and turning yellow about 7-10 days ago, although quite a few are still plenty green, and I'm going to let them go until they get mostly brown.
Am I doing something wrong? Or does homegrown garlic just never get as large as store-bought garlic?
