Do our gardening practices have a negative impact on the environment? Can we make a difference by changing the way we approach design, plant choice, planting techniques and maintenance regimes? How do we meet our aesthetic goals while providing the structure and resources necessary to maintain the insects and birds we love? Can we create healthy habitat with a mixture of native and exotic plants? These are a few of the questions to explore in terms of the hallmarks of sustainability when melding aesthetic expectations with ecosystem form and function.
