Which concept involves selecting and grouping plants with similar water needs?

• A. Aesthetic balance
• B. Moisture requirements
• C. Pest resistance
• D. Growth rate

Answer: (B)

Moisture requirements describe why you group plants by how much water they need. In landscape design, arranging beds into zones with similar irrigation needs—often called hydrozoning—lets you tailor watering to each zone, reducing waste and preventing stress from over- or under-watering. When plants with high water needs are mixed with drought-tolerant species, irrigation becomes inefficient and both groups can suffer. By aligning plants with comparable moisture needs, you can schedule watering more precisely and maintain healthier, more water-efficient landscapes. The other options relate to different traits or design goals: aesthetic balance is about appearance, pest resistance is about defense against pests, and growth rate is about how fast plants grow, not their water requirements.
