Combining flowers and vegetables in urban planter boxes is a fantastic way to maximize space, boost beauty, and enhance productivity. This practice, often called edible landscaping or companion planting, can lead to healthier plants and a more vibrant container garden. Here are five essential tips to ensure your mixed planter thrives.
First, prioritize compatibility. Choose plants with similar needs for sunlight, water, and soil. For example, pair sun-loving tomatoes, basil, and marigolds. The marigolds help deter pests, showcasing a key benefit of companion planting.
Second, master the art of vertical layering. Use the "thriller, filler, spiller" technique. Place a tall vegetable (like peppers) as the "thriller" in the center. Use mid-height plants (like lettuce or kale) as "fillers." Let trailing flowers (like nasturtiums or sweet alyssum) spill over the edges. Nasturtiums are also edible!
Third, ensure your container is large enough with excellent drainage. A depth of at least 12-18 inches is crucial for most vegetable roots. Always use high-quality potting mix, not garden soil.
Fourth, be strategic with feeding. Vegetables are heavy feeders. Use a balanced, organic fertilizer regularly to nourish both your edible and flowering plants without promoting excessive leafy growth at the expense of blooms or fruit.
Finally, practice attentive maintenance. Monitor for pests daily, water consistently (containers dry out fast), and harvest vegetables promptly to encourage more production. This keeps your mini-ecosystem balanced and productive.
By following these tips, you can create a stunning and bountiful urban oasis that delights the senses and the palate.
