Yes, you can absolutely mix different plants in the same urban planter boxes, and doing so can create beautiful, thriving container gardens. This practice, often called companion planting, allows you to maximize limited space while creating visually appealing arrangements. However, successful plant mixing requires careful consideration of several factors to ensure all plants thrive together.
The key to successful plant combinations lies in understanding each plant's needs. Group plants with similar sunlight requirements - don't mix shade-loving plants with those needing full sun. Consider water needs equally important; drought-tolerant plants like lavender won't thrive alongside moisture-loving plants such as ferns. Soil preferences matter too - some plants prefer rich, moist soil while others need well-draining, drier conditions.
When planning your mixed planter, think about growth habits and mature sizes. Include a "thriller" (tall, eye-catching plant), "filler" (medium-height plants that bulk out the arrangement), and "spiller" (trailing plants that cascade over the edges). This classic container gardening formula creates balanced, professional-looking displays.
Some excellent plant combinations for urban settings include mixing herbs like basil, thyme, and oregano with edible flowers like nasturtiums. For shady spots, combine ferns, hostas, and impatiens. In sunny locations, try pairing dwarf conifers with seasonal annuals and trailing ivy.
Remember to provide adequate soil depth and volume for root development, and ensure your planter has proper drainage holes. Regular feeding is crucial since multiple plants share nutrients from the same soil. With thoughtful planning and proper care, mixed planters can become stunning focal points in any urban space, providing both beauty and functionality throughout the growing season.
