Squeezing more plants into overcrowded garden beds or borders won't necessarily allow those plants to thrive. While relatively dense planting is often an excellent idea, introducing too much competition and too crowded an environment can do more harm than good.
But even when beds and borders seem full, you may still have space for plants that you might not have considered.
Thinking outside the box, you might be able to grow more food and other resources and obtain a higher yield. You might be able to boost biodiversity and do even more for wildlife. And you might be able to make your garden even more effective in a range of different ways.
