Garlic and other vegetables are heavy feeders that require high soil fertility to perform at their best. When nutrients are at optimum levels, vegetative growth is healthy, and plant size is maximized. Poor soil fertility is one of the most overlooked factors resulting in disappointing garden harvests.
To have the largest plants and bulbs at harvest, always use organic and natural fertilizer sources when possible!
