Thank you. Garlic needs very little space. All it needs is space for garlic bulb in the ground to grow. Garlic is probably the easiest thing I grow. You should totally try growing two garlic gloves in your smaller pots. Depending on variety, some bulbs get larger than others. Search the best time to plant garlic cloves in your area. You will be surprised with how easy and carefree it is to grow garlic.
