What does aquascaping refer to?

Aquascaping specifically refers to the design and maintenance of aquatic gardens. This practice involves creating visually appealing underwater landscapes using elements such as water plants, rocks, and driftwood arranged in a way that mimics natural ecosystems. Aquascaping often incorporates various techniques like planting aquatic plants and arranging hardscape materials to establish a harmonious balance in the aquatic environment. The key aspect of aquascaping is to create an aesthetically pleasing environment that can support aquatic life, enhancing both the beauty and functionality of the space.

In contrast, the other options do not capture the essence of aquascaping. The maintenance of terrestrial gardens involves plants and landscaping above water, while cultivating bonsai trees focuses on a specific style of growing and shaping trees, distinct from water features. The art of landscape painting, on the other hand, pertains to visual art and does not involve gardening practices at all.
