Planting & SoilQuestion 42 of 100

Which plant selection strategy BEST supports water-efficient landscaping in California?

a.Choose climate-appropriate, drought-tolerant plants grouped by water needs (hydrozoning)
b.Plant only high-water tropical species
c.Mix high- and low-water plants on one valve
d.Select plants at random from the nursery

Explanation

Selecting drought-tolerant, climate-appropriate plants and grouping them by similar water needs, called hydrozoning, lets each irrigation zone be scheduled efficiently. Mixing high- and low-water plants on one valve forces overwatering of the low-water plants. Hydrozoning is a core MWELO efficiency practice.
