Planting & SoilQuestion 27 of 100
Most landscape and turf plants grow best in soil with a pH in which range?
a.About 6.0 to 7.0 (slightly acidic to neutral)
b.About 3.0 to 4.0
c.About 9.0 to 10.0
d.Exactly 8.5
Explanation
A slightly acidic to neutral pH of roughly 6.0 to 7.0 keeps most nutrients available for uptake by common landscape plants and turf. Extremely acidic or alkaline soils lock up nutrients even when they are present. Acid-loving plants like azaleas prefer the lower end of this range.
