Planting distance for garlic.
This season I planted my garlic on ridges, centered on 83cm (33 inches). On top of each ridge I planted a double row. In the row I held a distance of 15 cm (6 inches). Yet, I wonder if, next season, I could plant three rows on a ridge. At the base the ridges are 50 cm (20 inches) wide. Do you think that, as a consequence, the dimensions of the bulbs coul suffer at harvest? The soil in my vegetable garden is a quite fertile loam which has been regularly amended whith horse manure and catch-crops such as rye. I also rotate the garlic bed in an eight year cycle.
