I have a couple onions and some garlic that went bad before I could use them but they have started to sprout. Is it ok to plant them and if it is, how should I plant them? Do I plant them with the part that is sprouting down or up? Is there another plant they are good to plant next to or bad to plant next to? Currently in my garden I have broccoli, radishes, cauliflower, spinach, romaine, iceberg, beets, carrots, 2 types of potatoes, pole beans, and lima beans. Thank you!!
