That's an excellent question! The number of plants you can comfortably fit in one of our medium-sized urban planter boxes depends on the mature size of the plants you choose. A good rule of thumb is to avoid overcrowding to ensure each plant has enough space for its roots to access water and nutrients, which promotes healthier growth and a better harvest.
For a typical medium planter box, which is roughly 24 inches long, 12 inches wide, and 12 inches deep, here are some general guidelines:
* For Herbs like basil, cilantro, or parsley: You can plant 3 to 4 plants. This gives them ample room to bush out without competing too heavily.
* For Leafy Greens such as lettuce or spinach: You can fit about 2 to 3 heads. They can be spaced a bit closer for a "cut-and-come-again" harvest.
* For Larger Vegetables like a single tomato or pepper plant: It's best to plant just one per box to allow it to thrive and support its full growth.
* For Flowers like petunias or marigolds: You can plant 2 to 4 for a lush, full display.
Always check the plant's specific spacing requirements on its tag or seed packet. When in doubt, less is often more. A less crowded planter is easier to maintain and results in happier, more productive plants.
