Only 10 of 64 garlic cloves sprouted
This was my second year planting garlic. The first year I planted 16 cloves from bulbs of an unknown hardneck variety obtained at the local farmers market. I planted the bulbs in a raised bed filled with garden soil. All were sprouted by the end of October, survived the winter just fine, and started growing like crazy the following spring. I saved a few of those bulbs for replanting and also ordered three other varieties: spanish roja and I forget the other two. I'll check when I get home. Last October I planted 64 cloves total of these four varieties in a recently-prepared raised lasagna bed. None had sprouted by the start of winter. This April, about 10 of the unknown hardneck cloves sprouted. None of the three new varieties sprouted.
Could the problem be that this was a new lasagna bed? Have others had problems growing garlic or other allium in new lasagna beds? I am pretty sure that I did everything else right, as far as planting time and depth.
