Why is spacing important in plant arrangements?

Spacing in plant arrangements is crucial primarily because it increases air flow around the plants. Proper spacing allows for adequate circulation of air, which is vital in reducing humidity levels around the foliage. This, in turn, helps prevent the development of fungal diseases and promotes healthier plant growth. Air flow is also important for pollination processes and for enabling sunlight to reach each plant effectively, optimizing photosynthesis.

While other factors such as fertilizer costs, soil quality, and aesthetic appeal can be impacted by plant spacing, the direct enhancement of air flow is a fundamental aspect that significantly contributes to the overall health and vigor of the plants. Healthy air circulation aids in mitigating diseases and pests, thus fostering a thriving garden or landscape.
