If you have a west-facing balcony, you're in luck! This orientation receives several hours of intense afternoon and evening sun, which is ideal for a wide range of plants that love warmth and light. The key to success in urban planter boxes is selecting varieties that not only tolerate these conditions but truly thrive in them.
For vibrant color, consider sun-worshipping annuals and perennials. Zinnias, marigolds, petunias, and geraniums will bloom profusely. Succulents like sedum and sempervivum are perfect low-maintenance choices, as they store water and handle heat with ease. Herbs are another excellent option; rosemary, thyme, oregano, and sage originate from Mediterranean climates and will flourish with ample sun and well-draining soil.
Don't overlook vegetables! Many fruiting plants need full sun. Cherry tomatoes, peppers, eggplants, and bush beans can be very productive in deep planter boxes. For greenery, ornamental grasses or a small, sun-tolerant shrub like dwarf lavender add structure and fragrance.
Your two main challenges will be heat and moisture. Afternoon sun can be intense, so choose deep boxes to hold more soil and prevent roots from baking. Watering is crucial; check soil daily in summer, watering deeply in the early morning. Using a moisture-retentive potting mix and applying a layer of mulch can help conserve water. With the right plant choices and a little care, your west-facing balcony can become a lush, productive urban oasis.
