Absolutely! Combining edible and ornamental plants in a single planter box is a fantastic way to maximize beauty and yield in small urban spaces. Here are five key tips for success.
First, practice "thriller, filler, spiller" design. Choose a striking central "thriller" like a dwarf fruit tree or colorful Swiss chard. Surround it with mid-height "filler" plants such as compact basil, nasturtiums, or lettuce. Finally, let "spiller" plants like trailing strawberries, sweet potato vine, or oregano cascade over the edges.
Second, match light and water needs. Group plants with similar requirements. For example, Mediterranean herbs like rosemary and thyme need full sun and well-drained soil, making them perfect partners for drought-tolerant ornamental succulents. For shadier spots, pair leafy greens like spinach with shade-loving ornamental coleus.
Third, prioritize soil and nutrients. Use a high-quality potting mix and a large enough container. Edible plants are heavy feeders, so incorporate a slow-release organic fertilizer at planting and use liquid feeds periodically to nourish both the edibles and ornamentals without sacrificing blooms or flavor.
Fourth, choose multi-functional plants. Many edible plants are gorgeous. Rainbow chard, purple basil, and flowering herbs add vibrant color. Nasturtiums and violas offer edible blooms. Ornamental kale is both stunning and tasty.
Finally, practice succession planting. As you harvest lettuce or herbs, have young ornamental seedlings or new edible starts ready to plug into the gaps. This keeps your planter looking lush and productive throughout the season.
By following these principles, you can create a living, edible masterpiece that delights the senses and provides fresh harvests right outside your door.
