Planning a small family herb garden is an exciting project. The number of urban planter boxes you need depends on a few key factors: your family's consumption, the available space, and the growth habits of the herbs you love.
First, list the herbs your family regularly uses. Common staples like basil, parsley, cilantro, mint, and thyme are great starters. A good rule is to dedicate one standard planter box (approximately 24 inches long) to one or two herb types. For example, one box for basil, one for parsley and cilantro together, and another for perennial herbs like rosemary and thyme.
Next, consider your space. Measure your balcony, patio, or windowsill. Ensure your planter boxes fit comfortably with walking space. For a small family of 2-4 people, a garden with 3-5 planter boxes is often sufficient to provide a continuous, fresh supply without overwhelming you.
Finally, think about plant needs. Some herbs, like mint, are vigorous spreaders and deserve their own container to prevent them from overtaking others. Taller plants like dill need deeper boxes. By matching the box to the plant's size and spread, you ensure a healthier garden.
Start with a modest setup of 3-4 boxes. You can always add more later as your confidence and love for gardening grow. Happy planting
