Why decide between flavor and beauty when you can have both in your window box? Edible-floral combinations are the latest trend in urban gardening, offering a feast for the eyes and the kitchen. Here's how to pair them:

Mix textures and heights: Place trailing herbs like thyme or strawberries along the edges with taller flowers like geraniums or peppers.
Color coordination: Rainbow Swiss chard looks stunning paired with purple petunias or deep-leafed sweet potato vine.

How to Plant and Care for Window Boxes

To ensure your window box garden thrives, a few fundamentals must be observed. Here are the essential steps and tips for healthy, productive window box plants:

Choosing the Right Window Box

Depth matters: Edible plants like tomatoes or carrots require deeper boxes (8-12 inches), while herbs and annuals do fine in shallower (6 inches).
Good drainage: Ensure your container has drainage holes to avoid root rot.
Material: Lightweight plastic or fiberglass boxes are easier for balconies, while wood offers classic looks (but may need lining).

Quality Potting Mix

Use a lightweight, high-quality potting soil enriched with organic matter. Fertilize every few weeks with a balanced, slow-release organic fertilizer, especially for hungry edibles.

Strategic Placement

Sunlight: Most edible plants and many flowers thrive in at least 4-6 hours of direct sunlight per day.
Accessibility: Place the box where you can easily water, trim, and harvest your plants.

Watering and Maintenance

Consistent watering: Containers dry out faster than ground beds. Water when the top inch of soil feels dry.
Pest and disease checks: Keep an eye on leaves for signs of problems and treat accordingly--prefer organic and safe pest control, especially for edibles.
Deadhead and harvest regularly: Pinch off fading flowers and trim herbs to keep plants producing and looking neat.

Creative Window Box Design Ideas

Get inspired to design a window box that stands out! Here are some popular themes to consider for a customized look and function:

Herb Kitchen Box: All-in-one culinary box with mixed herbs like basil, thyme, and parsley, plus nasturtiums for edible flowers.
Salad Bar Garden: Rows of baby lettuce, arugula, spinach, and a scattering of calendula for color.
Pollinator Paradise: Combine lavender, alyssum, marigolds, and strawberries for bees and butterflies.
Sensory Garden: Mix fragrant petunias and lavender, edible mint, and tactile foliage like dusty miller.
Shady Sanctuary: Use hosta, ferns, violas, and trailing ivy for north-facing or less sunny windows.
